I have been / am using C, C++ (Qt), Mapserver, Geoserver, Python, PHP, OpenLayers, OpenScales, Flex, R, GDAL/OGR library and Postresql/PostGIS extensively to develop webgis solutions as well as desktop solutions for access and analysis of geographic data. Currently working quite a lot on datasets from Airborne Laser Scanners' sensors applied to forestry and environmental analysis.
