One year of open governance for OTB: thoughts and context

One year ago, in the frame of the OSGeo incubation process, OTB team decides to initiate a Project Steering Committee to formalize the way that decisions are taken. It was largely inspired by existing governance in other OSGeo projects related to OTB like GDAL, Quantum GIS or GRASS. This initiative aims in encouraging people and organization to join the effort and participate more actively in the evolution and the decision process of the library. Most people well understand this approach and join the effort to provide high level guidance and coordination for the ORFEO ToolBox to guarantee that OTB remains open and company neutral. This presentation will come back on the set up of this open governance, how it improves the way that the project progress, how it could evolve in the future. It will be also the occasion to interact more largely about open governance and decision making processes in free and open source projects. Manuel Grizonnet (CNES)

ORFEO ToolBox status report

Orfeo ToolBox (OTB) is an open-source C++ library for remote sensing images processing. It has been initiated and funded by CNES (French space agency) in the frame of a program named ORFEO to prepare, accompany and promote the use and the exploitation of the images derived from Pléiades satellites (PHR). Orfeo ToolBox aims at enabling large images state-of-the-art processing even on limited resources laptops, and is shipped with a set of extensible ready-to-use tools for classical remote sensing tasks, as well as a fully integrated, end-users oriented software called Monteverdi and also access via Quantum GIS processing module. This presentation highlights new features included in the last version of OTB, mainly major improvements of the classification framework which facilitate large scale analysis for automatic image mapping, new methods for SAR image processing as well as a recap of the main features added in recent releases. It further shows the current and future directions of the project and opportunities for interested developers and users. The presentation will be also illustrate by example of how ORFEO ToolBox is used at CNES in the development of operational products, scale over France, like annual Land Cover Map or snow cover product to exploit ESA Sentinel missions provided with a free, full and open data policy adopted for the EU Copernicus program.

Digital field mapping with Geopaparazzi and gvSIG

Geopaparazzi is an application for fast field surveys. Its simplicity and the possibility to use it on as good as any android smartphone makes it a trusty field companion for engineers and geologists, but also for tourists who wish to keep a geodiary and any user that needs to be aware of his position even in offline mode. In Geopaparazzi it is possible to create text and picture notes and place them on the map. Notes can also be complex and form based in order to standardize surveys in which many people need to be coordinated. The data collected in the field can be directly exported from Geopaparazzi as KMZ or GPX. The plugin for Geopaparazzi in gvSIG supplies an userfriendly GUI with GIS functionalities to visualize all the data collected in the field, GPS tracks, text notes, pictures and form based notes and gives the possibility to save them as shapefiles. It works as a useful and fast tool to check the data collected in the field within a GIS directly from the file of the Geopaparazzi project without the need to export and save different shapefile. With this tool it is also possible to share projects with others, check the contents and periodically verify the results of the surveys.

Open Source strategies in a federal office - migrating from closed software to OS development

On of the task areas of the German Federal Office for radiation protection (BfS) in an case of a radiological emergency is to collect available and capture own relevant data, process and evaluate these and create documents including the necessary information to enable the crisis unit to make the right decisions for emergency preparedness and response. Some time ago, the BfS started to migrate from a proprietary monolithic system to an approach combining several OSGeo projects into a whole emergency system, including PostGIS, GeoExt, OpenLayers3, Geoserver, GeoNetwork and MapfishPrint and other software even from non-Geo but Open Source projects. To fill missing links between software components and to meet all demands of radiological disaster management, the BfS does not only use Open Source GIS software, but started several own software projects using free licenses as well. To seriously follow the Open Source strategy the BfS started to publish some of its projects using GitHub as a commonly used platform for Open Source projects, but not a common way for a federal office. The talk presents GitHub-driven Open Source projects of the BfS embedded in an OS driven software stack using several well known OSGeo projects.

OGC Soil Interoperability Experiment - Experiences in using a standard to exchange soil data

Soil data is crucial for environmental studies and analysis, but access to it and proper exchange formats and mechanisms are still poorly developed. The OGC Soil Data Interoperability Experiment (SoilIE), undertaken in the second half of 2015, had the objective of developing and testing a soil standard that harmonised existing standards defined in Europe and Oceania. During the SoilIE, participants from Europe, North America and Oceania mapped data in their soil databases to the SoilIE XML schema. Multiple OGC Web Feature Services (WFS) delivering soil observation data using the XML schema were established, along with OGC Web Processing Services to allow on-line derivation of new data. The SoilIE was successful with access to data in multiple clients from multiple soil data providers, each using different software configurations. The interoperability results will be presented along with next steps on progressing the SoilIE XML schema, RDF vocabularies, linked data and remaining major issues.

RESTful Geoprocessing API

We are seeing an increasing demand for a standardized REST binding for web-based geoprocessing. In this talk, we will present the ongoing discussions and developments that will lead to a RESTful binding for WPS 2.0. In the ongoing OGC Testbed-12, REST bindings for different OGC Web Services, among them WPS, will be developed and described in Public Engineering Reports. 52°North is leading the developments regarding WPS. However, this effort will need the support of the interested communities inside and outside the OGC. We want to use this talk to inform the audience about our concepts for a RESTful Geoprocessing API and we are eager to getting input for the way to go. Benjamin Pross (52°North GmbH)

A RESTful API for linking geodata

Publishing open data is a trend movement but still nowadays geographical information are often released as shapefiles despite this common format isn't recommended for such scope. We have used GeoNode, a spatial data infrastructure for publishing open geodata through standard OGC Web Services, with a RESTful API to model such resources to the semantic interoperability. GeoLinkeData is a django application based on a GeoNode template that allows to publish interlinked shapefiles as triple stores and search them with GeoSPARQL queries from a Virtuoso backend.

Develop without developing

As a gis manager in a city you often don’t have time or resources to do coding. But with powerful tools like Qgis and PostGIS you maybe not need to. In Kristianstad, Sweden, we had an outdated system for greenspace management. We were not satisfied with the commercial options. Thus we decided to build the new system in Qgis and PostGIS with just standard functionality such as spatial queries, forms, relations etc. I will present the work and some technical hints. Quite simple but yet powerful solution. No need to overdo things. Karl-Magnus Jönsson (Kristianstads kommun)

Crunching Data In GeoServer: Mastering Rendering Transformations, WPS Processes And SQL Views

This presentation will provide the attendee with an introduction to data processing in GeoServer by means of WPS, rendering transformations and SQL views, describing real applications and how these facilities were used in them. We'll start with the basic WPS capabilities, showing how to build processing request based on existing processes and how to build new processes leveraging scripting languages, and introducing unique GeoServer integration features, showing how processing can seamlessly integrate directly in the GeoServer data sources and complement existing services. We'll also discuss how to integrate on the fly processing in WMS requests, achieving high performance data displays without having to pre-process the data in advance, and allowing the caller to interactively choose processing parameters. While the above shows how to make GeoServer perform the work, the processing abilities of spatial databases should not be forgotten, so we’ll show how certain classes of processing can be achieved directly in the database. At the end the attendee will be able to easily issue WPS requests both for Vectors and Rasters to GeoServer through the WPS Demo Builder, enrich SLDs with on-the-fly rendering transformations and play with SQL views in order to create dynamic layers.

Creating Stunning Maps in GeoServer: mastering SLD and CSS styles

Various software can style maps and generate a proper SLD document for OGC compliant WMS like GeoServer to use. However, in most occasions, the styling allowed by the graphical tools is pretty limited and not good enough to achieve good looking, readable and efficient cartographic output. For those that like to write their own styles CSS also represents a nice alternatives thanks to its compactness and expressiveness. Several topics will be covered, providing examples in both SLD and CSS for each, including: mastering multi-scale styling, using GeoServer extensions to build common hatch patterns, line styling beyond the basics, such as cased lines, controlling symbols along a line and the way they repeat, leveraging TTF symbol fonts and SVGs to generate good looking point thematic maps, using the full power of GeoServer label lay-outing tools to build pleasant, informative maps on both point, polygon and line layers, including adding road plates around labels, leverage the labeling subsystem conflict resolution engine to avoid overlaps in stand alone point symbology, blending charts into a map, dynamically transform data during rendering to get more explicative maps without the need to pre-process a large amount of views. The presentation aims to provide the attendees with enough information to master SLD/CSS documents and most of GeoServer extensions to generate appealing, informative, readable maps that can be quickly rendered on screen.

Keynote V - Openness, the bridge to societal impact with data re-use

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.

Keynote III - Geospatial Analytics in Risk Management

At the Joint Research Centre (JRC), scientists involved in maritime situational awareness are confronted with a growing volume of data. Every day millions of ship positions from terrestrial and satellite receivers are gathered globally and in real-time, as well as optical and radar Earth Observation images, leading to a significant variety of data. To support the researchers, policy makers and operational authorities in their activities a analysis platform with WebGIS functionality has been developed with the aim of turning data into valuable information and demonstrating pre-operational tools for maritime awareness. The platform is mostly based on FOSS software and consists of a front-end visualization tool and a back-end analysis engine. Fusion algorithms provide the ability to integrate data from multiple sources on the fly. A series of tools provide predictive analysis, activity mapping, anomaly detection, and cross disciplinary information, to support maritime security and safety and to improve marine knowledge. The web application is developed using open source programming languages (e.g. Javascript, Python), frameworks (e.g. Django, Geoserver), and interchange data format (JSON) to enable researchers to seamlessly integrate ad hoc algorithms developed in scientific languages (e.g. R, Matlab). A case study will be presented, showing examples of how the WebGIS architecture can provide visualisation and analysis tools to support decision makers and scientific and operational actors in the fields of fisheries science, maritime spatial planning, and maritime surveillance.
