Geodetic Programs by KilletSoft

GeoSoftware Within the division "Geodetic Software" KilletSoft is focusing on the development of user friendly geodetic applications. By our online presence in the Internet these applications benefit very strongly from the user feedback. We develop applications, in which again and again incorporate the ideas and desires of the users and thus lead to meaningful updates of the software. Particularly proud we are on the program TRANSDATpro, which can accomplish worldwide geodetic coordinate-transformations and datum-shifts between the unbelievably lots of different state-specific systems, and which has reached a high name recognition in the meantime.
