Objective of the research. The improvement of a methodology of a city’s 3-dimensional geoinformation system development, updating and registration of changes by applying geodetic and photogrammetric measurements.

Recently three-dimensional graphics is being applied in many fields. It is used in geodesy, topography and architecture as well. There are a lot of programs for the work with 2D and 3D graphics in the world. Most of them are related by CAD name. It could be mentioned such production of graphic software „giants“ like Autodesk (AutoCAD, Map 3D ) or Graphisoft (ArchiCAD). The aim of our work is the program which main function is the generation of three-dimensional city. Obviously this could be done using programs mentioned above, but the assimilation of such program needs much time and money. Therefore, if we need only to generate 3D city, our program is suitable for this. Our program quickly retrieves topographic data of the city and generates its 3D view. The program is not overloaded with unnecessary functions. It makes the program easy to understand and assimilate for the user who has minimal knowledge in design and modelling.
