SE-AGETIM-LIGHT is simple standalone software that enables easy 3D environment generation that can be used for simulation and modelling. SE-AGETIM-LIGHT enables integration of various geographical data sources with Global MapperTM GIS. Physical database extensions mechanisms are provided for a highly automated multi sensor generation process. There are dedicated algorithms for data cleaning and automatic mapping. Too complex data are simplified, or ignored, so that the generation process runs smoothly. Generation parameters are gathered on a single window which can be adapted to specific customer needs.
