The hydrogeological model of Latvia will be elaborated in the time period from 2010 to 2012. It will be used for management of groundwater resources of Latvia. The 3D-body to be modeled is represented by 95160125 finite difference grid which plane approximation step is 500 metres. The model will be created in the framework of the commercial program Groundwater Vistas, which includes the worldwide used MODFLOW system for running the model. As initial information for creating the model serves a set of digital maps (elevations of geological layer surfaces, permeability of layers, boundary conditions, etc.). Creating maps regarding geometry of the regional model (the digital ground surface map included) is the most difficult task, because geological layers to be modeled are of highly irregular nature. Methods and tools applied for creating initial data maps are described.
