This map demonstrates the use of the ZOO-Project's vector-based spatial analysis through WPS services (specifically OGR base-vect-ops), as served through MS4W, to leverage the power of MapServer on Windows. The data is stored in a Spatialite database, and accessed through MS4W's WMS service (sending GeoJSON output).

Click a country and then select a single geometry tool (that will appear in the top panel). Then click another country and select a multiple geometries tool.

Please refer to spatialtools-py-app.js to see how this is done.
