9. Orfeo Toolbox Processing http://orfeo-toolbox.org
10. Orfeo Toolbox Remote sensing image library Open Source Developped by the French Space Agency
11. Orfeo Toolbox More than 70 high level processing chains orthorectification segmentation classification etc.
12. Orfeo Toolbox More than 70 high level processing chains orthorectification segmentation classification etc. Supervised learning (land cover is computed from a set of "well known areas" given by user) Based on SVM (http://en.wikipedia.org/wiki/Support_vector_machine)
13. Web application mapshup http://mapshup.info
14. mapshup Improves access to geospatial data HTML + javascript Based on OpenLayers and jQuery
15. mapshup Supported data sources WMS WFS CSW WPS OpenSearch etc. Flickr Youtube GeoRSS KML Wikipedia Google maps Bing maps OpenStreetMap MapBox WMTS
