Today we finally released the first version of Geopaparazzi on the android market. The project is released under GPLv3 an available on the homepage of the project.
Geopaparazzi is a tool developed to supprot very fast qualitative engineering/geologic surveys. It integrates completely with the BeeGIS digital tablet extentions, i.e. the data are imported straight into the GIS from the phone for further processing. See this link for an example.
Geopaparazzi is sold on the Android market and supports the development of Geopaprazzi itself as well as the projects developed by the same team: JGrass, JGrassTools and BeeGIS.
That said, I leave you to the documentation on the main website.
