The practical part is focused on, firstly, relabelling of the current data which is necessary for the unequivocal identification of data. Secondly, the data model in the Oracle database for Digital Terrain Model of the Czech Republic of the 5th generation savings is created. Finally, the possibilities of evaluation of new data, creation of a script and a tool for ArcGIS (for generation of the most recent Digital Terrain Model of the Czech Republic of the 5th generation model) are dealt with.
