The economics of bringing a new geo product to market by leveraging open standards, FOSS and FOSS4G

The cloud and open source software have fueled a wave of innovation that has enabled both large and small companies to bring products to market more easily and with less cost and friction than ever before. This talk will describe our journey to bringing such a new product to market. In 2014 Google began selling its high resolution imagery and purchasers received the data as large buckets of files deployed within Google’s Cloud Platform (GCP). This opened a requirement for high performance serving of that imagery via the Open Geospatial Consortium’s (OGC) WMS and WMTS standards. This talk will describe the process of a small company developing this image serving technology by both incorporating and contributing to open source and geo open source initiatives. The talk will describe the market opportunity for the new product as well as the business case that led us to choosing an open source approach even for something that is ultimately sold. The talk will also describe the Node.js technical approach that was chosen and the array of geo tools, such as Mapnik and PostGIS, and other open javascript frameworks (e.g. Bootstrap, Handlebars.js, etc.) that underpin the solution. The talk will also highlight our development team’s open source contributions back to projects and the community. The talk will conclude with a description of the lightweight server and its features that enable an “imagery as a service” business model that daily serves hundreds of users in Utah and Texas.

Create Vector Tiles from OpenStreetMap

The OSM2VectorTiles project offers free downloadable vector tiles ready to use by people interested in hosting custom base maps on their own infrastructure. The whole world fits on a USB stick and can be served from an ordinary web hosting and styled and enriched to make beautiful and fast maps for web and mobile applications. The advantages of vector tiles over traditional raster tiles are well known. There are already a handful of vector tile provider present, but they may not always serve your use case optimally. After this talk you will know how to create your own custom vector tiles based on OpenStreetMap and will know the tools and processes you need to use. The talk will cover how to import OpenStreetMap data into PostGIS and then shows how to generate vector tiles using Tilelive and Mapnik. We will present the open source workflow we use at OSM2VectorTiles to prerender global vector tiles and instruct you how to adapt the workflow to create custom vector tiles. Thanks to Docker and tools such as Mapnik, PostGIS, Tilelive and Mapbox Studio Classic the process is straightforward and repeatable.

Leveraging Big Geo Data through Metadata

The increase in the scale of traditional data sources, along with an explosion in the availability of sensor data, have originated massive volumes of data, a great deal of which is actually geolocated. This is partly due to the wide adoption of cheaper position technologies, and to the exponential growing of Volunteered Geographic Geographic Information (VGI) movements, which rely on crowdsourcing approaches. Big Data has generated a lot of interest amongst industry, the developer community and the public in general, and it has been at the core of many technology innovations which took place recently (e.g.: NoSQL, MapReduce); these new approaches already started to involve the geo community with projects such as the ESRI Spatial Framework for Hadoop or GeoTrellis, just to mention a few. However, the focus has been mostly on storing data (at the infrastructure level) and using data (at the analysis level), leaving aside challenges such as discoverability, integration or security. In this talk, we will address some of these outstanding challenges through the use of metadata and the semantic web, and show how the use of a decentralized and standardized catalog can help to unlock the five V's of Big Data: Volume, Velocity, Variety, Veracity, and most importantly, Value.

Sensor Web for Oceanology

In the marine community, observation data sets are a critical input for many scientific questions. Thus, significant investments are made in equipment and data acquisition technology. To ensure that the collected data is efficiently used by a larger number of researchers, the interoperable sharing of observation data is getting more attention in recent time. This presentation introduces open source Sensor Web components from several European projects such as NeXOS, FixO3, BRIDGES and ODIP II that cover different requirements for Sensor Web technology in marine applications. On the one hand there are server-side tools such as the 52°North Sensor Observation Service which facilitate the publication and download of marine observations. On the other hand this is complemented by tools such as the 52°North JavaScript SOS Client, which offers a lightweight approach to explore and visualise observation data sets generated by mobile (e.g. research vessels) as well as stationary sensors (e.g. buoys). In our presentation we will introduce the basic principles of an interoperable Sensor Web infrastructure for Oceanology as well as show how this infrastructure can be implemented using the open source software components of 52°North.

QWCII: A new QGIS Web Client

QGIS Web Client (QWC) is a Web-GIS client based on OpenLayers 2 and ExtJS and tailored to use special extensions of QGIS Server, such as extracting information from QGIS Project settings, extended GetFeatureInfo Requests, GetPrint and DXF export. It uses standard WMS/WFS commands, but extends them where needed. QWC is used by several cities and provinces in Europe. There are four main reasons why QWC needs to be overhauled: The code structure is not very modular and should be better structured. QWC only works well on Desktops. Despite a separate mobile web client based on OpenLayers 3 and jQuery Mobile, for maintenance reasons it would be much better to have a single web client that uses responsive design and works for all devices from a single viewer. The base libraries ExtJS 3.4 and Openlayers 2 have been phased out and there are newer versions available. However, the upgrade to the newer versions is not trivial. Having a more modern foundation based on newer web technologies This presentation discusses the requirements, the progress of this project, technical decisions taken and challenges solved during the project. While the first goal of the project is to establish a modern foundation for the coming years and reach feature parity with the old QWC project, it is already planned to implement a QWCII python plugin that offers a GUI and assists with the global configuration of the client. This tool should also facilitate the management of topics and projects.

GeoServer in Production: we do it, here is how!

The presentation will describe how to setup a production system based on GeoServer from the points of view of performance, availability and security. The suggestions will start covering how a single node GeoServer should be prepared for internet usage, tuning logging, connection pools, security, data and JVM preparation, keeping disk, memory and CPU usage in check within the limits of the available resources. We’ll then move to tools used to monitor the production instances, ranging from probes to request auditing and watch-dogs. Finally the presentation will cover setting up a cluster of server and the strategies for keeping them in synch, from the traditional multi-tier setup (testing vs production) to the systems that need to keep an ever evolving catalog of layers constantly on-line and in synch.

Validating services and data in an SDI

To achieve interoperability in a spatial data infrastructure (SDI), conformance to specifications is essential for services and data. Service and data providers need a capability to validate their components. For several OGC standards, the OGC CITE tests provide such a capability. This covers base standards, but in SDIs typically additional specifications are added, for example, service profiles or data specifications. In the European Location Framework (ELF) the test framework ETF is used to validate INSPIRE services and data provided by National Mapping Authorities against the INSPIRE Technical Guidelines as well as against ELF-specific requirements. ETF is a test framework for spatial data infrastructure components. It supports SoapUI (for testing web services) and BaseX (for testing XML documents, including very large ones) as test engines to develop and execute test suites. ETF has been implemented in several iterations over recent years as existing open source test environments could not be configured to provide uniform test reports that were readable by and useful for non-developers. Outside of the ELF project, ETF is currently mainly used in Germany and the Netherlands, partly extending the INSPIRE-specific tests based on national profiles. We present the approach for developing user-friendly test suites and discuss typical issues that have been encountered in the ELF testing.

Integration testing of Web Mapping applications (including web mapping server) using Python

When you are developing applications, you need to write tests. A unit test is a test written by the programmer to verify that small piece of code is doing what it is intended to do. The tests are intended for the use of the programmer. An integration test on the other hand is done to demonstrate that different pieces of the system work together. Integration tests cover whole applications, and they require much more effort to put together. The integration tests do a more convincing job of demonstrating the system works than a set of unit tests can. Unit tests can be great but they tightly couple your tests to your code, making it really fragile and anti Agile. We will show integration testing of web mapping applications using Python bindings to Selenium browser automation tool. We can test JavaScript application from Python environment, using standard unittest module. Since Python is very easy to be used and it's very universal language, it's easy to be learned by non-programming co-workers, who can automate application tests and help the developers with testing. Using integration tests in continuous integration development, enables us to be more agile, making sure that both parts - frontend and backend remain integrated even bigger refactoring occures. Part of testing is also background data services, with new project called WMSChecker. This is used in our Jenkins environment, so that system administrators can have overview about current status of running custom nad 3rd party services.

How the Land Administration community profits from Open Source

The Social Tenure Domain Model (STDM) is a concept, model and information tool to map people-to-land relationships. STDM is developed and maintained by the Global Land Tool Network (GLTN) under the lead of the UN Habitat. The data model was closely aligned with LADM, an ISO standard on Land Management followed by most implementers. When it came to implementing the software tool the GLTN group decided against reinventing the wheel but to check out existing Open Source components (as maintained by the OSGeo Foundation) and Open Standards (as maintained by the OGC). So basically everything from the data model, technology standards and up to all the tools required to do proper Land Administration is already there. But it is too complex for non-technical people to grapple with. Therefore the GLTN group started to implement a software package which shipped with the right data model for the Postgres and PostGIS database, the desktop software QGIS, reporting tools and comprehensive documentation. This presentation will give an overview of the software tool and underlying components to give participants with limited technological background a better understanding of how it works and how they can also profit from the abundance of great Open Source software that is out there.

Development of a new framework for Distributed Processing of Big Geospatial Data

The Geospatial world is still facing the lack of well-established distributed processing solutions tailored to the amount and heterogeneity of geodata, especially when fast data processing is a must. However, most current distributed computing frameworks have important limitations regarding both data distribution and data partitioning methods. Hence, this paper presents a prototype for tiling, stitching and processing of big geospatial data. The system is based on the IQLib concept developed in the frame of the IQmulus EU FP7 research and development project. The data distribution framework has no limitations on programming language environment and can execute scripts (and workflows) written in different development frameworks (e.g. Python, R or C#). It is capable of processing raster, vector and point cloud data. Our intention is to provide a solution to perform a wide range of geospatial processing capabilities in a distributed environment with no restrictions on data storage concepts. Our research covers methods controlling data partitioning, distributed processing and data assimilation as well. Partitioning (also referred to as “Tiling”) is a very delicate yet crucial step having impact on the whole processing. After algorithms have processed these “chunks” or “tiles” of data, partial results are collected to carry out data assimilation or “Stitching”. The paper presents the above-mentioned prototype through a case study dealing with country-wide processing of raster imagery. Assessment is carried out by comparing the results (computing time, accuracy, etc.) to concurrent solutions. Further investigations on algorithmic and implementation details are in focus for the near future.

Flood mapping and analysis platform based on open satellite data and free and open source geospatial

Flooding remains the most widely distributed natural hazard in Europe, causing significant economic and social impact. Nowadays, availability of earth observation data generates fundamental contributions towards mitigation of detrimental effects of extreme floods. The technological advance allows development of online services able to process high volumes of satellite data without the need of dedicated desktop software licenses. The talk presents the data, the algorithms and the technologies used to develop such an online system that can use multi-scale satellite data, together with reference and in-situ information, to map the areas affected by floods and giving the users the possibility to inspect, process, analyze and validate the information. The platform, created by National Meteorological Administration of Romania, offers services based on Open Geospatial Consortium standards for data retrieval (WMS, WCS, WFS) and server-side processing (WPS, WCPS). The services were built using open source solutions such as GeoServer, OpenLayers, PostGIS, GDAL, rasdaman.

Enterprise Single Sign-On in GeoServer: where do we stand?

Security is a major concern in the enterprise and treats all aspects of identity and access management. Moreover the proliferation of devices and digital assets connected to the Internet of Things is a massive source of growing geographic information. GeoServer has buit-in a lot of features to manage authentication and authorization but often this kind of problem can be better dealt with a dedicated tool (i.e. Forgerock IAM suite) which allows to provide identities and access policies likewise to several clients. What are the best practices to integrate GeoServer into an existent single sign-on and identity lifecycle? Althought tools like CAS and GeoFence allow to enable such features it's more likely that GeoServer needs a leaner and cleaner path towards the externalization of authentication and authorization for the OGC services and its REST API.

The Evolution of the GeoNode Community

The GeoNode project has grown from an idea and a handful of early partners 5 years ago to a large and thriving open source project and downstream ecosystem. This talk will discuss the cast of characters and organizations that currently contribute to GeoNode, how this community has grown and evolved over time and the growing pains encountered and lessons learned in the process. Particular focus will be paid to the technical and collaborative aspects of growing and managing a diverse community, looking at how new community members are brought into the fold and how the resources that organizations with different needs and requirements bring to the table are marshaled most effectively to achieve economies of scale when developing new features. The GeoNode community has begun a quantitative analysis of organizational return on investment from open source and initial results of this study will also be presented.

From global observations to local information: The Earth Observation Monitor

Earth Observation (EO) data are available around the globe and can be used for a range of applications. To support scientists and local stakeholders in the usage of information from space, barriers, especially in data processing, need to be reduced. To meet this need, the software framework "Earth Observation Monitor" provides access and analysis tools for global EO vegetation time-series data based on standard-compliant geoprocessing services. Data are automatically downloaded from several data providers, processed, and time-series analysis tools for vegetation analyses extract further information. A web portal and a mobile application have been developed to show the usage of interoperable geospatial web services and to simplify the access and analysis of global EO time-series data. All steps from data download to analysis are automated and provided as operational geoprocessing services. Open-source software has been used to develop the services and client applications.

Using SQLite to take maps offline on mobile devices

Nowadays, the internet allows us to access maps on mobile and tablet devices in real-time when we need them. Very often we might be without an internet connection. How to get access to maps in such situations? The answer is to take maps offline. What are technical challenges to get maps offline? Why is SQLite ideal database for offline map storage? How to store all vectors and rasters into a single SQLite database on a mobile device? How to render such maps using hardware with limited capabilities? What are storage and bandwidth requirements? How to solve offline map editing and synchronization? These are only some of the questions this talk will focus on.

OSGeo conference videos as a resource for scientific research: The TIB|AV Portal

This paper reports on new opportunities for research and education in Free and Open Source Geoinformatics as a translational part of Open Science, enabled the growing collection of OSGeo conference video recordings at the German National Library of Science and Technology (TIB). Since 2015, OSGeo conference recordings have been included to the collection sphere of TIB in information sciences. Currently, video content from selected national (FOSSGIS), regional (FOSS4G-NA) and global (FOSS4G) conferences is being actively collected. The annual growth exceeds 100 hours of new content relating to the OSGeo software projects and the OSGeo scientific-technical communities. This is seconded by retrospective acquisition of video material dating from past conferences, going back until 2002 to preserve this content, ensuring both long term availability and access. The audiovisual OSGeo-related content is provided through the TIB|AV Portal, a web-based platform for scientific audiovisual media providing state-of-the art multimedia analysis and retrieval. It implements the requirements by research libraries for reliable long term preservation. Metadata enhancement analysis provides extended search and retrieval options. Digital Object Identifiers (DOI) enable scientific citation of full videos, excerpts and still frames, use in education and also referral in social networks. This library-operated service infrastructure turns the audiovisual OSGeo-related content in a reliable source for science and education.

Urban SDG Measuring System using the Open Geospatial Data of the International Organizations

As a post Millennium Development Goals(MDG), 17 Sustainable Development Goals(SDG) and 169 indicators were adopted at 2015 in the UN general assembly. Especially as the developing countries are predicted to face rapid urbanization until the 2030, Cities attract more and more attentions for achieving SDGs because most activities occur in the cities. But the activities are closely related to spatial phenomena. It is essential to consistently construct the spatial database for developing and developed countries and uniformly measure and monitor the indicators of urban SDGs which is operationally defined in this presentation as a SDG 9 and 11. In this regards, open geospatial data present both possibilities and limitations for urban SDG measurement. In this presentation, we analyze open database from UN agencies and Multilateral Development Banks(MDB) and measure and predict the urban SDG until the 2030 using that database. To that end, we analyze the related open data structure of those international organizations and develop a UN SDG monitoring system based on the FOSS4G solutions such as PostGIS and GeoServer.

PROBA-V mission exploitation platform

In januari, the European Space Agency launched the first version of the PROBA-V mission exploitation platform. proba-v-mep.esa.int. This platform, which is fully operated by VITO Remote Sensing, has the goal to simplify the use of open remote sensing data which should eventually result in operational applications that benefit society. Exploitation platforms are the way of the future to handle the ever increasing volumes of remote sensing data, and at VITO we believe that the use of Open Source software is the only way to collaborate on this shared vision. In this talk, first I want to give a general overview on what users can do with the PROBA-V MEP. This involves using an Openstack VM loaded with FOSS software and direct access to the dataset, to access an Hadoop cluster where a user can distribute his processing using Spark. Secondly, I want to show how we are using Geotrellis to support interactive queries on the full timeseries of remote sensing data that is available in the platform. Also showing how this can be done from within an interactive Scala notebook in the browser.

Towards open, interoperable, and transdisciplinary point clouds for high performance computing

Large point clouds have emerged across a wide range of disciplines, however users and managers face a bewildering range of storage formats, large datasets and convoluted workflows for analysing point clouds alongside other data. Services like OpenTopography and the PDAL toolkit enable point cloud discovery and use, but integration with other earth systems data is not transparently supported. The Australian National Computational Infrastructure (NCI) hosts 10+PB of research data, predominantly in the realm of Earth Systems. These include extensive point cloud data which need to be discoverable alongside, and interoperable with, substantial collections of geospatial observations and model data using common tools in a High Performance Computing (HPC) and High Performance Data (HPD) environment. NCI has created a National Environmental Research Data Interoperability Platform (NERDIP) to help manage and analyse the data, both locally and remotely using web services which makes use of advanced features in HDF/NetCDF. We have demonstrated that deploying other geospatial data using a HDF5 model has the potential to directly improve large-scale usage and increase data interoperability between diverse geospatial collections. Models such as the Sensor Independent Point Cloud (SIPC) and SPDLib are based on HDF5. NCI are currently evaluating the use of these formats to aid discovery, extraction and processing using readily available tools, as well as interrogation via web services. The end goal for NCI is making point data discoverable and accessible to end-users in ways which allow seamless interoperability with other datasets and processing techniques.

Mapping WiFi measurements on OpenStreetMap data for Wireless Street Coverage Analysis

The growing interest on smart cities and the deployment of an ever increasing number of smart objects in public locations, such as dumpsters, traffic lights, and manholes, requires ubiquitous connectivity for these devices to communicate data and to receive configurations. Opportunistic WiFi connectivity is a valid alternative both to ad hoc solutions, like LoRa, which require costly deployments, and to communicating through the mobile network, which is both pricey and battery power hungry. In this paper we present a tool to analyze the WiFi coverage of home Access Points (AP) on the city streets. It can be of interest to ISP or other providers which want to offer connectivity to Internet of Things smart objects deployed around the city. We describe a method for gathering WiFi measures around the city (by leveraging crowdsourcing) and an open source visualization and analysis web application to explore the accumulated data. More importantly, this framework can leverage the semantic information contained in OpenStreetMap data to extract further knowledge about the AP deployment in the city, for example we investigate the relationship between the AP density per square kilometer within the city and the WiFi street coverage ratio

Real-time large format maps for passenger information on railway disruptions

Focusing on a clearer and more visible passenger information, Swiss Federal Railways SBB modernized the general displays in the biggest Swiss railway stations. The former mechanical palette displays were replaced by LED screens of up to 5 meters width. In case of severe traffic disruptions these monitors are used for providing the passenger with general information. Additionally, a huge (perhaps the biggest) map based on OpenLayers 3 is shown on the monitor enabling the passenger to get a fast overview of the situation. The key component of the service-based architecture is the geographical content management system Cartaro. It is used by the employees in the SBB operation centers for composing and editing the information to display. Among issues like performance, reliability and availability a major challenge for the system was the development of tools for the fast and simple creation of a clear and appealing map. The software automatically generates a map based on real-time timetable information, identifies the affected stations and highlights the interrupted route using a routing-based approach. A set of integrated spatial editing tools enables the user to e.g. modify route geometries at different generalization levels and to align map labels.

OSGeo AGM

After 5 years in production the open source based Pavement Management System for Ireland has amassed over 15 years of road-related data. The back-end mapping engine is powered by MapServer and we are looking to improve performance when dealing with more and more data. The talk will focus on how to set up Locust, an open source Python load testing tool, to automatically get average load times for each WMS and WFS layer from MapServer, and how many users MapServer can handle concurrently. A small open source project is currently being written to help this process. Whilst MapServer is the focus of the talk, any OGC-compliant server can be tested in the same way. The talk will then briefly run through a series of experiments to see how changing various components affects performance. These are: Running MapServer on Linux as compared to Windows Using the MapServer native SQL Server driver, and using the OGR driver Map file size Venkatesh Raghavan (Osaka City University)

Identification of SAR Detected Targets on Sea in Near Real Time Applications for Maritime Surveillance

Remote sensing technologies are widely used in maritime surveillance applications. Nowadays, spaceborne Synthetic Aperture Radar (SAR) systems provide outstanding capabilities for target detection on sea for large areas independently from the weather conditions. Complementary information from the Automatic Identification System (AIS) makes it possible to generate a value-added target-detection product. Resulting layers on the maritime situation – once provided to decision makers - would be highly beneficial in order to understand what is going on at sea and how it would impact on Maritime Safety and Security. This paper describes the approach of SAR-AIS data fusion and its visualization means developed for Near Real Time (NRT) Applications for Maritime Situational Awareness.

Bringing benthic data to the surface - moving Marine Recorder into an open source spatial database.

The Joint Nature Conservation Committee (JNCC) is one of a number of organisations that run inshore and offshore surveys to collect data on seabed biodiversity (e.g. species records and habitat types). The main storage and collation system for these data is Marine Recorder, a Microsoft Access-based database application developed by JNCC in 2002. Despite several updates since then, the system is now significantly out of date, and the lack of internet connectivity or the ability to store spatial data is a major problem. As a result of these issues, organisations in the UK that collect benthic data are investigating more up-to-date systems and there is a significant risk of data fragmentation. JNCC are currently in the process of moving all of our spatial data from a file based system into PostGIS. This talk will describe JNCC’s open-source geospatial information strategy and how we are integrating Marine Recorder into this, discussing the efficiency savings that this provides, as well as our plans for developing a full open-source, online replacement for Marine Recorder in the future.

Kickstart your web map app!

Do you want to avoid writing boilerplate code for map applications? Would you rather take a ready-made template for your apps and start hacking away the cool stuff? Oskari and RPC may be just what you're looking for! Oskari is an extensible and versatile map application platform which provides an easy user-interface for creating embeddable maps to websites. Embedded maps can be controlled from the website with an API to create innovative and user-friendly applications. The API includes features that allow you to 'visualize data' on the map and/or 'react to user interaction' with the map, allow users to give feedback by 'drawing on the map' or create a custom trip planner with routing features. The API can be easily extended by adding features to Oskari platform. Oskari has been originally developed by the National Land Survey of Finland, but now being developed and used by multiple organizations, also internationally. There are numerous websites already making use of embedded maps, including Finnish national e-services.

Mastering Security with GeoServer and GeoFence

The presentation will provide an introduction to GeoServer own authentication and authorization subsystems. We’ll cover the supported authentication protocols, such as from basic/digest authentication and CAS support, check through the various identity providers, such as local config files, database tables and LDAP servers, and how it’s possible to combine the various bits in a single comprehensive authentication tool, as well as providing examples of custom authentication plugins for GeoServer, integrating it in a home grown security architecture. We’ll then move on to authorization, describing the GeoServer pluggable authorization mechanism and comparing it with proxy based solution, and check the built in service and data security system, reviewing its benefits and limitations. Finally we’ll explore the advanced authentication provider, GeoFence, explore the levels on integration with GeoServer, from the simple and seamless direct integration to the more sophisticated external setup, and see how it can provide GeoServer with complex authorization rules over data and OGC services, taking into account the current user, OGC request and requested layers to enforce spatial filters and alphanumeric filters, attribute selection as well as cropping raster data to areas of interest.

Unleashing the potential of your sensor data with istSOS

istSOS is a complete and easy to use sensor data management system for acquiring, storing and dispatching time-series observations. istSOS is compliant with the Sensor Observation Service standard (SOS) version 1.0 and 2.0 from the Open Geospatial Consortium (OGC) and offers unique extended capabilities to support scientific data analyses (integrated quality assurance, RESTful API, on the fly processing with virtual procedures, remote data aggregation, time-space re-projection etc.). istSOS core libraries are written in Python while it easy to use interface is Web based. This presentation will illustrates the projects and its latest enhancements, including: The OGC SOS 2.0 standard implementation Authentication and Authorization System Alert and Notification system Finally the presentation will discuss the challenges that istSOS need to face for entering in Big Data showing results of scalability tests and ongoing new IoT driven development features. The robustness of the implemented solution has been validated in a real-case application: the Verbano Lake Early Warning System. In this application, near real-time data have to be exchanged by inter-regional partners and used in a hydrological model for lake level forecasting and flooding hazard assessment. This system is linked with a dedicated geoportal used by the civil protection for the management, alert and protection of the population and the assets of the Locarno area.

MapStore 2, modern mashups with OL3, Leaflet and React

MapStore 2 is an overhaul of the existing MapStore with the goal of creating a webmapping framework which is more lightweight but still modular and easy to work with. It can leverage both OpenLayers 3 or Leaflet as the mapping engine and uses ReactJS and Redux as the core JavaScript libraries. Moreover a 3D viewer based on CesiumJS is available. MapStore 2 is both a framework and a standalone application. You can use it as a framework to develop your custom WebGis application composing MapStore ReactJS components and components from other libraries (like React Bootstrap), choosing the best mapping library for your purposes. You can also use the MapStore2 application directly, to create, save, and share in a simple and intuitive way maps and mashups created by selecting content from the server such as Google Maps, OpenStreetMap or WMS and WMTS. The MapStore 2 application consists of two main components MapManager and GeoStore, respectively front-end and back-end. MapManager allows through a unique interface to create, modify, delete and search on maps definition as well as generate a univoque link to embed a map in an external website, share your own maps with the others. GeoStore implements a flexible Java Enterprise infrastructure to manage and search maps with proper management of authentication and authorization. The presentation will give the audience an extensive overview of the MapStore 2 functionalities for the creation of mapping portals. Eventually, a range of GeoSolutions case studies of MapStore 2 will be presented.

Hosting vector tile maps on your own server

Custom styled map of the whole world served from your server? Easy! This talk shows examples of practical use of the vector tiles downloaded from the OSM2VectorTiles project or other tiles in MVT format. A new open-source project called TileServer GL is going to be presented. This project serves JSON map styles into web applications powered by MapBox GL JS library as well as into native mobile SDKs for iOS and Android. The same style can be rendered on server side (with the OpenGL acceleration) into good old raster tiles to ensure compatibility and portability. Maps can be opened in various viewers such as Leaflet, OpenLayers, QGIS or ArcGIS. Alternatively it is possible to use a tileserver powered by Mapnik to render the raster tiles out of vector tiles and existing CartoCSS styles made in MapBox Studio Classic. Other approaches for independent hosting and using of vector tiles are going to be presented as well.
