We implemented it for biological hotspots in India for a client. The system has all the basic navigation tools and area/usage/application specific query tools which is the back bone of the SDMS. Developed completely using open source tools, its back end can be any spatial database including postgresql, mysql, oracle or ESRI’s Geodatabase.

Main properties are

  • OGC compliant solution
  • High end customisable queries
  • Opacity control of the layer
  • Multi GIS format support
  • Commercial API’s like Google, Yahoo as base layers
  • Search layer (vector) turn on/off
  • Layer manager with draggable layers
  • Navigation tools, overview map etc

The first website implemented over SDMS was launched by Nandini Nadkarni, member of faculty of Evergreen state college, Olympia, Washington on October 26th 2009 International Canopy congress, Bangalore, India.

Below given is a demo video showing main capabilities of the system.

There are occasions i wish i had more tools from openlayers. Of course it offers loads of classes , we need to know Javascripting in and out in order to customise the interface. Mapfish uses an external javascript library called extJS.

Here comes the advantage of mapfish , a comparitively new release in the world of open source tools for geospatial. Mapfish provides both client and server (java and python). Client is built up on openlayers and added more functionalities. I tried out their demos , quite impressive especially the examples on geostatistics. We can use mapfish client with almost all other servers, and offers everything which openlayers has and more customised tools.

It uses the Geojson format for the geostat examples. I really liked this one and it has other potential applications like dynamic symbology . The GeoJson format is light weight and simple to handle, so quite fast in the application.
An blog on this by Bjørn Sandvik in his thematic mapping blog
I will give an example in the next post.
I would say we can compare the functionalities with that of new ArcGIS server 9.3 Javascript API.

Geoserver can serve WFS service in GeoJson format , What more can you ask for, So get ready for more applications using Geoserver and Open layers/MApfish.
Enjoy the freedom.
