Information about GeoTec GmbH Geodetical Technologies in D-30880 Laatzen, Germany. We are specialised in developing software for use in applied geodetics. Our product, the Program System PANDA, permits the adjustment and analysis of height (1D), positional (2D) and spacial(3D) geodetical networks, a deformation analysis of observations taken in two epochs - i.e. for the surveillance of structural objects - and the transformation of coordinates between two different coordinate systems i.e. from WGS84 into a national system. Levelling, tacheometer and GPS data can be processed and it is also possible to process a combination of tacheometer and GPS observations. We also offer Customer Services, which include the evaluation of observations and the development of individual, customised surveying-software solutions.
