Turf: New Open Source WebGIS

We begin year 2015 with pretty interesting and major news. WebGIS is one giant step closer to be seriously useful, thanks to the new open source WebGIS project named Turf.

From the MapBox announcement: “Turf is GIS for web maps. It’s a fast, compact, and open-source JavaScript library that implements the most common geospatial operations: buffering, contouring, triangular irregular networks (TINs), and more. Turf speaks GeoJSON natively, easily connects to Leaflet […]  Unlike the ArcGIS API for JavaScript, Turf can run completely client-side for all operations, so web apps can work offline and sensitive information can be kept local. We’re constantly refining Turf’s performance. Recent research algorithms can make operations like clipping and buffering faster than ever, and as JavaScript engines like V8 continue to optimize, Turf will compete with native code. […] With the building blocks for GIS analysis on the web, you can create your next spatial application in a whole new way: as small pieces joined together intelligently using Turf.”

You can try the examples yourself from MapBox’s entry or look at the list and try examples directly on Discussing Turf and why it may succeed, Howard points to Plasio, point cloud rendering capability in a browser for Lidar data. Geospatial directly on the web might indeed see great progress this year.

10th International gvSIG Conference: reports, posters and articles

We would like to inform you of the availability of presentations, posters and articles presented during the 10th International gvSIG Conference [1], which were held from December 3rd to 5th in Valencia (Spain).

The videos of the report sessions and workshops are also available to be visualized online. All the videos are available with English and Spanish audio, excepting the three workshops given on Wednesday and Thursday, that are only in Spanish.

With this publishing, we pretend to bring the Conference closer to the interested people that couldn’t attend the event, having the possibility to access to the recording of the different sessions.


What’s next for FOSS4G-Asia: Seoul 2015!

After the success of the first FOSS4G-Asia in Bangkok last week, we could see a trend in this part of the world in the next years to come. The market seems to be dominated by users and small-medium enterprise for now. As for the use case, disaster management is likely to be on the top of the list, a prove of that is the most popular workshop was the InaSafe one (as a plugin in QGIS). This project uses OpenStreetMap data as input and other open data to analyse scenario of disaster on risk reduction. This project has been applied mostly in Indonesia which has built with the Australian government its capability of risk analysis with now over 1.3 millions of building mapped and involvement of HOT (OSM) Team over the years. With over 110 persons attending this FOSS4G-Asia event from 18 countries (Nigeria, Canada, Germany, Laos, South Korea, Vietnam, Indonesia, Japan, etc.), this event was more open to other parts of the world than what we could think at first.

The best user of FOSS4G-Asia was given to eHealth Africa in Nigeria for their work towards polio eradication and Ebola outbreak and their use of FOSS4G such as: OSRM, MapServer, QGIS and CKAN.
The best software development was given to MapMint and their team of developers.
Finally, this Asian community will be involved again next year at the international FOSS4G 2015 in Seoul (which will include a technical session only for Asia).

foss4g2015_cSanghee Shin from South Korea gives seven reasons why people should go to Seoul next year, such as people (the Asian market is the biggest in the world), South Korea government investment in open source (9 million over the next years), the culture (Asian culture is vibrant) and most of all, because it is with distance that comes new connection!

Day 3: FOSS4G-Asia

On Day 3 at FOSS4G-Asia, different open source projects were presented to the crowd, such as: Geopaparazzi, Tadpole SDM and Policrowd 2.0.


First, Geopaparazzi is an Italian Android project to do field survey, but also tools that can be of great use also to OpenStreetMappers as well as tourists that want to plan their trip.  Some can see Geopaparazzi  as an apps similar to OSMAnd, even if the clients at first were not the same.

Secondly, Tadpole SDM has been shown for the first time at FOSS4G-Asia. It is a web-based UI in Java to manage spatial database based on Tadpole DB. It is at early stage, so it only supports PostGIS for now, but they plan in three years to support Oracle, MySQL, SQL Server and Spatial Lite. It can manage spatial data, work as Saas, draw query geometry quickly, show select row table, display which database objects has spatial data.

Thirdly, Policrowd 2.0 has been recently released and extending its uses. It is a social platform over Nasa WorldWind and Open Data Kit as a GIS participatory web application, allowing users to populate a virtual 3D globe with their personal geospatial information and with OGC compliant service (ex. WMS).

Finally, governments were also part of the development and user process at FOSS4G-Asia, especially in South Korea and Quebec in Canada. South Korea just release its Open Source Geospatial Policy by sharing resource in GIS and find better ways to collaborate. South Korea launch also a government funded R&D program of over 9 million with goals of developing and enhance their GeoEcosystem with github platform, KAOS-G forum, new project architecture based on GeoTools-GeoServer-OpenLayers, process Spatial-Statistics and collaboration with Kazakhstan Government. In Canada, the government of Quebec with its new project called: Open GIS Infrastructure (IGO in French) has also been presented. IGO includes: (like South-Korea) a collaborative platform (Gitlab, Redmine), project governance based on UMN MapServer committee rules and target at sharing expertise, documentation and resource within the government. This IGO project involved 6 organisations in Quebec. It develops WPS spatial analysis tools (based on Zoo Project), security management on layers, an API over OpenLayers, Geoext, MapServer using Phalcon as Integrator model. This project will enable anyone to configure by a simple XML its own web map application including Base Map and WMS/GeoJSON overlays in a layer tree and adding different built-in functionalities (ex. adding WMS server on-demand, share permalink, location tool) to the apps without any lines of javascript. The source code of IGO should be released in 2015 as a LGPL licence and the government of Quebec is looking at other public administration (local, regional and national) in Canada or elsewhere to get involve or contribute to the project.

For the last day of FOSS4G-Asia a sprint code was held on Zoo Project to continue enhancing this open WPS platform.
