A Cross National Comparison on the Awareness of Adopting FOSS4G to NSDI in Developing Countries

Spatial data infrastructure (SDI) plays an important role in the sharing and exchange of spatial information of the country, in this way, it has also played a major role in the development of the country's economy and society. In recent years, FOSS4G (Free Open Source Software for Geospatial) provides functionalities that are not inferior to commercial software, which lead to the diffusion of that software to the public and private sectors. Developing countries which have poor information infrastructures, there are increasing discussions about the adoption of FOSS4G to their national spatial data infrastructure (NSDI) in order to utilize the benefits of the foundation. As the benefits of FOSS4G adoption, it has suggested the low introduction cost and interoperability of software that does not depend on the specific software. But there are differences on the pros and cons of FOSS4G adoption to their NSDI because each country has their own economic and technological development stages and cultural and institutional differences. In this research, we will develop the framework to compare and evaluate the relationships between indicators on the developing countries' economic, technological development and factors in the introduction of FOSS4Gs to their NSDI and conduct a survey on the developing countries’ FOSS4G adoption to their NSDI with the help of UN GGIM(United Nations Global Geospatial Information Management) and KOICA. Thus, by comparing and evaluating each country's FOSS4G adoption to NSDI according to their countries' economic and technological development stage, we will identify the awareness of the adoption and propose a deployment strategy for overcoming the disadvantages when developing countries consider the introduction of FOSS4G to their NSDI.

Saving Rapid Urbanizing Cities using the FOSS4G Based Spatial Analysis for Urban Development

Early stages of urban developments such as housing construction, new town development and urban regeneration are performed through the spatial analysis using the topographic map, cadastral map, zoning map and other various kind of thematic maps for the proposed site analysis, feasibility analysis and evaluation of urban development alternatives. For these analyses, urban developers traditionally have used commercial software like ArcGIS to analyze these kinds of projects. And giant Korean public urban developer like Korea land and Housing Corporation (LH) has support these projects based on the in-house enterprise GIS system. But developing countries facing rapid urbanization near the peripheral areas of metropolitan region cannot handle such problems only using the commercial software. They need knowledge and experience about the urban development rather than complicated software based analysis techniques or large investments on the enterprise GIS system. In this sense, FOSS4G (Free Open Source Software for Geospatial) are very useful tools in that they are easy to learn, use and also relatively cheap to maintain. LH has accumulated a lot of urban development cases and wants to store this knowledge to FOSS4G based spatial analysis as a rule base. By doing so, it can manage the fast growing cities sustainable. In this presentation, we will show some conceived urban development project faced by the rapid urbanizing cities and suggest FOSS4G based spatial analysis method using the FOSS4G like QGIS plug-in.

A glimpse of FOSS4G in the environmental consulting arena

In the highly competitive world of environmental consulting, being able to manage large volumes of data and deliver timely, accurate information based on that data is critical to our ongoing success. As a relatively small company, we recognized that we needed something unique to survive and prosper in an industry dominated by huge corporations. Over the past 7 years we have made a considerable effort to shift over to a FOSS4G environment, with a belief that, not only would this decision enhance what we already do well, but give us the competitive edge we would need to ensure future prosperity.A brief presentation of a snapshot of our current FOSS4G status, how we arrived here and a workflow tour beginning at the data acquisition stage looking at the feed through our patented EDMS QA/QC system into PostgreSQL followed by a demonstration of a just a few of our many custom web/mobile/desktop applications that rely on the PostgreSQL back end database and how these solutions are able to deliver accurate and timely information to employees and clients alike, and finally, where to next.We take advantage of multiple FOSS4G including the likes of OpenLayers, MapServer, PostgreSQL/PostGIS, PHP, D3 and jQuery. This combination places us in an ideal position to respond to client needs with the ability to rapidly deliver almost any request.

Geosocial Big Data Analysis Using Python and FOSS4G with the Case Study of Korean Data

Nowadays, there are many researches on the analysis of Geosocial big data, such as geotweeet and as foursquare venues and OSS(Open Source Software) has an important role on this. In the analyzing geosocial big data, there are several different steps such as data collection, data parsing, data conversion, statistical analysis, visualizing and database management. So, the integrated system architecture and the compatible analysis environment has a key role to acquire the relevant analysis results. The Python programming support the interoperable analysis environment for the various and different software functions and enable to process for geosocial big data in the integrated platforms. FOSS4G support software environment for geovisualization and data management for the collected data. In this study, the way and process of geosocial big data analysis is introduced with case study of geotweet and foursquare venues and the analysis results are presented with the case study of Korean data. For this study, Python API libraries for tweeter(tweepy) and foursquare(pyforsquare) used to collect the geosocial data, and Pandas and Simplejson are used to parse and extract the valid data, and GDAL and PySAL are used to convert and analyze for GIS data. PyTagCloud and WordCloud are used to visualize the qualitative text. MongoDB is used to store the collected dataset and QGIS are applied for the geovisualization.

Case study: A full-fledged cutting-edge FOSS4G map production system

The development and the usage of National Land Survey of Finland's dynamic and high performance map production system is described in this presentation. The system is currently in use and serves map images both to customers and to NLSFI production systems. The data in the map production system are open data and being updated on a weekly basis. When the data get updated, a RSS-feed is generated. Based on the feed, the map products are updated. Data is stored, updated and replicated in PostGIS. Map pictures are rendered in GeoServer. The visualization of the maps is based on SLD-stylesheets. SLD-stylesheets enable the same data to be visualized in several different ways. GeoServer in conjunction with SLD-stylesheets offers a Web Map Service (WMS). Map images are delivered via a high performance MapCache Web Map Tile Service (WMTS) and as image files via NLSFI download service. The system is designed to be expandable and is currently being further developed to enable the pro-duction of on-demand printed maps.

Sapporo Childcare Map: Making the city makting the city a little better with FOSS4G

The Sapporo Childcare Map developed by Code for Sapporo is an interactive map covering childcare facilities including daycare centers and kindergartens located in the city of Sapporo, Japan. The first version of the map was developed using OpenLayers 3 as the mapping library. The map allows users to search by operating hours, eligible ages, vacancies, and other parameters. The service helps parents to find childcare facilities based on various criteria. With the rising rate of double-income families, finding openings at public daycare centers in large cities is becoming more challenging. The childcare maps based on the Sapporo's system were also developed in other cities with support from Code for Japan.

Evaluating Flood Hazard Potential in Danang City, Vietnam Using FOSS4G

This study aims to build flood hazard map for a lowland area in Danang city, Vietnam based on topographical data, land-cover and flood inundation map. ALOS PALSAR imageries with respect to the time before and during flood event in 2007 were used to characterize flood inundation. In addition, topographical data was developed via 5m resolution DEM generated by a bi-cubic spline algorithm that implemented in BS-Horizon program (Nonogaki et al., 2012). This high resolution DEM was used to enhance the accuracy of flood map as well as determine the geomorphological features of the study area and the relations on flood hazards. Land-cover map in 2007 extracted from Landsat TM data was also applied for the landform classification process. The flood hazard map was generated based on the probability of submergence of each landform unit. The changes in land-cover as well as topography have significant effect on flood hazard. In this study, optical Rapid Eye remote sensed data in 2014 was used to extract land-cover by the time and the land-cover change from 2007 to 2014. The estimated landform and potential flood hazard map in 2014 was built based on the updated land-cover. The result was compared with field survey flood pillar data, flood map in the past, land-cover change and flood scenario given by Danang City government to assess the accuracy. This research has also proposed some flood prevention plans for this alluvial lowland area. Landforms units derived rule-based classification of land cover map, 5m resolution DEM data and flood inundation map not only facilitates the understanding of the nature of flood but also in flood risk zoning. The methodology developed in this study would be useful in low relief areas in Vietnam and other parts of the world.

Integrating FOSS4G into an enterprise system for Disaster Management

ROGUE (Rapid Open Geospatial User-Driven Enterprise) was a project funded under the Joint Capability Technology Demonstration (JCTD) Program from the U.S. Department of Defense. Boundless and LMN Solutions, LLC implemented the project, with the Pacific Disaster Center (PDC) serving in the role of project Transition Manager. The project's goal was to improve the abilities of the OpenGeo Suite to ingest, update, and distribute non-proprietary feature data in a distributed, collaborative, and occasionally disconnected environment. Under this project, PDC integrated the following technologies into its decision support system for emergency managers named DisasterAWARE:- GeoGit: Versioned replication of spatial data across multiple sites, supports disconnected editing and conflict resolution. - Arbiter: Android app for field data collection, syncs to GeoNode.- MapLoom: GeoNode GUI for spatial data editing and management. - KML Uploader: Functionality to upload KML for storage in PostGIS and served via GeoServer. - GeoServices REST (GSR): Extends GeoServer to publish data using the REST methodology of ArcGIS Server. This presentation will cover the integration of these components into DisasterAWARE, along with the security framework implemented for all components.

The role of geospatial open source (FOSS4G) as a component of hybrid systems

Currently, it is rare that an organization faces a choice between "just commercial" or "just open source" geospatial software. Increasingly, the answer isn't about "or", it is now about solutions that may involve both. Indeed, Commercial systems - both installed software and cloud-based platforms - may have both functional and cost effectiveness gaps. Free and open source software for geospatial (FOSS4G) can be a critical component that helps to bridge these gaps. And, given that organizations may have large existing investments and sunk costs in commercial software it can make sense to leverage those investments by building hybrid systems that incorporate open source components. This presentation will describe several specific examples of hybrid systems that incorporate geospatial open source (e.g., OpenGeo Suite) alongside both Esri and Google components. The presentation will focus on both the business reasoning for choosing hybrid as well as the technical approaches taken. Ultimately, hybrid projects or systems can be very important as they provide a key entry-point for geospatial open source into organizations that might not otherwise consider it.

Educating 21st Century Geospatial Technology Industry Workers with Open Source Software

Where are GIS educators to go when they need educational material to teach FOSS4G in their academic programs? While commercial vendors, like Esri through their Virtual Campus, have a wealth of training material available, there are very limited resources for educators seeking to teach FOSS4G. The new QGIS Academy program is the first national effort to provide this much need academic infrastructure. The Academy has produced a set of five full GIS courses, based on the latest version of QGIS, to offer educators and others for free under the Creative Commons CC BY license. These courses have been under development since 2010 and use the US Department of Labor Geospatial Technology Competency Model (GTCM) as the basis for their scope and sequence. This presentation will demonstrate the courses and discuss their development and future plans.

Community Health Mapping

This talk will cover a FOSS4G case study in which a workflow was implemented in several minority public health organizations in 2013. The three organizations were: 1) the Urban Indian Health Institute (Seattle, WA), 2) Papa Ola Lokahi (Honolulu, HI) and 3) The Nature Conservancy of Hawaii (Honolulu, HI). The end users were not GIS professionals but public health staff. Such community based public health organizations do not typically have dedicated GIS staff or budgets for GIS. However, they have each identified mapping needs. The overarching goals of the project were to demonstrate that FOSS4G tools could be effective in minority public health applications, and that they could be used by non-GIS public health staff. Therefore, a focus was placed on identifying the most intuitive and low cost solution meeting their needs.The workflow started with field data collection and included spatial analysis and online data presentation. Field data collection was performed using smart phones and tablets that the end users already owned. Analysis was done via QGIS and final data presentation was done via GIS Cloud. Training sessions were conducted and support was provided throughout the year. However, each organization was able to use the tools with very little follow up support. Each project produced good results, and each is planning on continuing with additional projects in 2014. The workflow will be introduced and results of the three case studies shared.This work was funded by the National Library of Medicine's Division of Specialized Information Services via their Outreach and Special Populations Branch.

Earning Your Support Instead of Buying it: A How-to Guide to Open Source Assistance

More organisations are moving to use FOSS4G software to cover shrinking budgets. It is very appealing to an organization’s leaders to ditch their current proprietary software solution with the attendant saving on per user licences and ongoing maintenance costs. Obviously, if you switched to FOSS4G to get better features and scalability you should consider buying a support contract from one of the many vendors that offer them, these companies support many of the core developers directly. This way you get all the advantages of open source, prompt support and often the chance to ask for new features. However, if you (or your boss) are looking to save money then you are moving from a cash economy to a gift economy. In a gift culture you need to build up your “capital” before attempting to take too much out. For example, you’ve downloaded the software and installed it, and all looks good. Then disaster hits, you have a demo for the CIO and nothing's working; Time to hit the user list, the developer list, stack exchange. Why can’t you get an answer? Remember just because your issue is urgent to you the developers might be in the middle of a new release or adding a new feature and have more important (or fun) things to do with their time. They will notice they have never seen your name before on the list, or on Stack Exchange that you have a reputation in the single digits – thus you are a newbie. There’s no harm in that but wouldn’t it be better to have got that out of the way before your emergency. You could have built up your reputation by asking some questions earlier especially questions like “what can I do to help?” or “I found an unclear paragraph in the install instructions, how do I fix it for you?” on a mailing list. On StackExchange you can build reputation by asking good questions and by answering other people’s questions. Once you’ve banked some capital there are still good and bad ways of asking a question. Developers are busy people (the GeoTools users list has 20-30 messages a day for example) no one has time to read all of them closely. If you use a poor subject (e.g. "Help!!!!") or don’t provide a clear description of the problem (e.g. “it crashes”) then the odds of being ignored are huge. It can be tempting once you have found a helpful developer to keep emailing them directly, but this is likely to lead a polite(ish) reminder to keep to the list so that everyone can benefit or silence. This talk will show how to be a better open source citizen and get a better answer than RTFM when your project is stuck and the demo is the next day. The author will share his experience with helping users and developers on the GeoTools and GeoServer mailing lists and as a moderator on gis.stackexchange.com.

A spatial view in the culture heritage domain

Culture heritage institutions are hosting digital historic map collection and the collections more and more allow spatial-temporal searching and georeferencing of its maps. At the Saxon State and University Library Dresden (SLUB) this lead to the development of the Virtual Map Forum 2.0, which is a spatial data infrastructure (SDI) for searching, visualization and georeferencing plane survey sheets. This SDI mainly relies on OpenLayers 3, Mapserver, GeoNetwork and GDAL. Beside that, tools for automatic georeferencing based on image recognition software have been developed and compared with the use of crowdsourcing tools for georeferencing. A further topic, on which culture heritage institutions are focusing is enrichment, transformation and merging of existing heterogeneous metadata sets. The goal is to allow better searching and utilization approaches for digital and analog objects. In the SLUB this lead to the development of the open source ETL-tool d:swarm, which supports the transformation and enrichment of metadata records. This opens possibilities for adding spatial identifier to large amounts of library objects, like pictures, newspaper articles or books and through this allows for a greater consideration of the spatial dimension in discovery systems. Another big topic is long term preservation, which becomes even more important with the growing number of digital native publications and datasets. Libraries and archives as experts of long term preservation and spatial data infrastructure provider, which are confronted with tasks and questions regarding the preservation of content. They therefor can benefit from an exchange of knowledge and work between each other. The presentation will give an insight into the world of culture heritage institutions. It will present topics, where FOSS4G and libraries can benefit from each other. Therefore it discusses different issues from within the SLUB where FOSS4G is used or could be used and spatial issues are affected. The main topics are spatial-temporal searching and visualization, georeferencing, metadata enrichment and long-term preservation.

GIS Policy Map for Local Government in Korea: Story of Dobong-gu, Seoul

Local governments in Korea are trying to solve urban problems using GIS policy map. Through FOSS4G Seoul, I want to introduce example of Dobong-gu, Seoul. Topic 1. Spatial Analysis of Practical Requirements of Parking Lot The residents who live in the old residential zone in Dobong-gu are suffering from shortage of parking spaces every morning and night. Most administrators are using an indicator named ‘a ratio of cars to parking spaces’ to judge seriousness of the problem with parking. But the indicator cannot reflect reality. We measured practical requirements of parking lot spatially, using micro block data and car registration data with addresses. We tried to look at things from the resident’s perspective, not from administrator or provider. Now, Dobong-gu push ahead with sharing parking lot program with houses which have spare parking spaces. Topic 2. Civic Participation Model for Solving Children’s School Walkway Safety Problems. Office of Policy Development of Dobong-gu did a survey with a thousand residents about safety issue, and many of them answered that they feel fear walking down the alley. Although the Office got the policy implication from survey, they couldn’t convince the definition of ‘alley’ and accurate location where the residents feel fear. Office and we redesigned survey paper cooperatively. The improvement point was ‘Map-based Survey’. Elementary school students and their parents participated and they lined school walkway and alleyways where they felt fear on paper map. We migrated all the lines on papers to shape files using QGIS, then we got a very satisfactory outcome. Office of Policy Development added LED lights to the dark street nearby elementary school, Elementary school teachers decided the walkway guidance spot by referring to students often jaywalk.

What's new in Cesium: the open-source alternative for 3D maps

When building 3D mapping apps, we no longer have to deal with closed feature-sets, limited programming models, temporal data challenges and bulky deployments. This talk introduces Cesium, a WebGL-based JavaScript library designed for easy development of lightweight web mapping apps. With live demos, we will show Cesium's major geospatial features including high-resolution global-scale terrain, map layers and vector data; support for open standards such as WMS, TMS and GeoJSON; smooth 3D camera control; and the use of time as a first-class citizen. We will show how Cesium easily deploys to a web browser without a plugin and on Android mobile devices.Since last year's talk at FOSS4G NA, Cesium has added 3D models using the open-standard glTF, a large geometry library and higher-resolution terrain.

pyModis: from satellite to GIS maps

One year after the first public presentation of pyModis at FOSS4G 2013 a lot of improvements have been implemented in the pyModis library. The most important news are that each command line tool now offers a graphical user interface to assist inexperienced users. Furthermore, the MODIS Reprojection Tool (MRT) is not longer mandatory in order to mosaic and reproject the original MODIS data as GDAL is now supported.Hence the most important improvement was the reimplementation of existing MRT component to use the Python binding of GDAL. This was basically driven by the fact that MRT does not properly perform geodetic datum transforms as discovered in the daily work with MODIS data within the PGIS-FEM group leading to shifted reprojection output. With the new GDAL support not only this problem has been solved but also the installation greatly simplified. pyModis is used all over the world in academic, governmental and private companies due to its powerful capabilities while keeping MODIS processing workflows as simple as possible.The presentation will start with a small introduction about pyModis and its components, the library and the tools. This part is followed by news about the latest pyModis release and indications about future developments.

Geodesign: An Introduction to Design with Geography

Geodesign, at its most basic, is design with geography. It is the combination of the tools and techniques geographers and other geoscientists use to understand our world with the methods and workflows designers use to propose solutions and interventions. For instance, the typical master planning process in which GIS-based knowledge is separated from the design process can be turned into a geodesign task by sketching buildings and other land uses directly within a GIS, and seeing indicators update on the fly as various data graphics. This can then allow the designer(s) to pinpoint specific design interventions based on live feedback from geospatial information.Over the last 10 years, technology has facilitated an explosive growth in geodesign as both a framework for solving problems and a toolkit of geospatial analyses that feed into that framework. The growth of the Geodesign Summit in Redlands, CA from 2010 to 2014 is an example of the demand for this sort of framework.Parallel to the rise of geodesign, the tools represented by FOSS4G have also been evolving into sophisticated tools capable of taking on the needs of geodesign. However, to date there's been too little discussion of how to take the framework and working methods of geodesign and accomplish them with open source tools. This session will connect those dots by taking the typical parts of a geodesign framework (suitability analysis, sketching/designing, evaluating/comparing, iterating) and outlining our own experience making use of open source tools for geodesign. In particular, we will focus on how the interoperability of open source tools and the growth of web-based geospatial tools can support (and evolve!) the ways that geodesign is done.This presentation will address:What is geodesign: the conceptual framework and typical use cases for geodesignWhere are we: workflows and tool stacks we've used and seen others use to dateWhere could we go: identifying current gaps and pain points in existing stacks and possible solutions from emerging technologies

GIS goes 3D : an OpenSource stack

3D in GIS is already here, with more and more data available, and new hardware and sensors for 3D data capture and interaction. The third dimension becomes useful for several use cases and applications, since the technology is now available to achieve full 3D spatial analysis, like 3D intersections, 3D buffers, triangulation and a lot of other data processing capabilities we already use with 2D data. 3D Point clouds from Lidar data, 3D Meshes or TIN, this can now be stored and processed.With 3D data, an absolute must-have is a nice, fast and smooth rendering of features. Visualization is a key element of a complete vertical software stack of 3D data management.This presentation will demonstrate the ability to setup and take advantage of a full FOSS4G 3D stack.Taking data from 3D sensors, or real use-case GIS Open Data, we present the components which can be used together to build the core infrastructure of 3D data management. From data storage to data visualization, through processing and webservices.* Learn how you can use PostgreSQL and PostGIS latest enhancement to store and process 3D data.* Discover how you can setup 3D Web Services for data dissemination* Visualize 3D data with QGIS thanks to the Horao Plugin* Find out the visualization tools available for your favorite browser (Three.js powered)Here we are, a full 3D stack, with OpenSource tools. Software components, data formats, protocols and standards, you will get a global picture of the infrastructure available to extract the value out of your 3D data.

Responsive Interactivity: Toward User-centered Adaptive Map Experiences

In recent years, the web design community has moved quickly to accommodate the various devices and methods for accessing web content. The FOSS4G and wider development community have responded to this paradigm of adapting the layout of content to scale to the device of the user by creating and leveraging tools such as Leaflet and D3. However, there remains a lack of knowledge, understanding, and conversation about what it truly means to create a map experience that meets the present needs and expectations of the user. Designing an adaptive map should go beyond simply fitting it into a responsive layout. User variables, such as the mode of interaction and location-based needs, raise map-specific UI design questions that this community is uniquely positioned to answer.This talk will explore what it could mean cartographically and experientially to adapt all aspects of the map experience to the needs of the user using principles already embraced in other communities. Our goal is to provoke a wider discussion of how we, as a community, can work toward these objectives. Regardless of expertise level, anyone who is involved with the creation of interactive web maps has inevitably come across the problems associated with, and will benefit from involvement in this conversation.

From Nottingham to PDX: QGIS 2014 roundup

Following the long awaited QGIS 2 release, announced at FOSS4G 2013 in Nottingham, the project decided to switch to a regular release cycle with three versions per year. QGIS 2.2 was the first release in this cycle and already packed with many new features like 1:n relations, gradient fills, native DXF export and NTv2 datum transformations to name a few. QGIS 2.4, released in June, has one major extension in its core: multithreaded rendering. Originally developed as a Google Summer of Code project, it makes a big difference in the responsiveness of QGIS desktop.This talk shows a selection of the latest features and gives an outlook what's in the works for QGIS 2.6. Some interesting plugins and other news from the community will keep you up to date with the high pace of this OSGeo project.

OSGeo Incubation

The Open Source Geospatial Foundation does much more than hold FOSS4G each year.This talk will look into what makes OSGeo a software foundation. What software foundations have to offer members, software projects and developers.This talk is structured around the "incubation" process by which new software projects join the OSGeo.If you are new to open source take this is a great chance to see how OSGeo evaluates software projects and how these checks protect you!For managers it is especially important to understand the risks associated with the use of open source. Understand what assurances OSGeo incubation offers, how to double check the results, and what factors are left for your own risk assessment.If you are a developer considering getting involved in OSGeo this is great talk to learn what is involved, how much work it will be, and how you can start!Come see what makes OSGeo more than a user group!

GRASS GIS 7: your reliable geospatial number cruncher

GRASS GIS (Geographic Resources Analysis Support System) looks back to the longest development history in the FOSS4G community. Having been available for 30 years, a lot of innovation has been put into the new GRASS GIS 7 release. After six years of development it offers a lot of new functionality, e.g. enhanced vector network analysis, voxel processing, a completely new engine for massive time series management, an animation tool for raster and vector map time series, a new graphic image classification tool, a "map swiper" for interactive maps comparison, and major improvements for massive data analysis (see also http://grass.osgeo.org/grass7/). The development was driven by the rapidly increasing demand for robust and modern free analysis tools, especially in terms of massive spatial data processing and processing on high-performance computing systems. With respect to GRASS GIS 6.4 more than 10,000 source code changes have since been made.GRASS GIS 7 provides a new powerful Python interface that allows users to easily create new applications that are powerful and efficient. The topological vector library has been improved in terms of accuracy, processing speed, and support for large files. Furthermore, projections of planets other than Earth are now supported as well. Many modules have been significantly optimized in terms of speed even by orders of magnitude. The presentation will showcase the new features along with real-world examples and the integration with QGIS, gvSIG CE, R statistics, and the ZOO WPS engine.
