Regional Maps – type of digital maps with medium-sized resolution used for networks planning and optimization projects over large regions or countrywide.

Regional Models data set:
- Digital Terrain Model (DTM) - Clutter / Land Use Model (13-18 classes) - Vector Model (8 classes) - Text Labels (names of settlements, rivers, railways, etc.) - Resolution: 20-50 m - Sources: Satellite images with 5-15 m resolution, SRTM/ASTER DEM data, Topographic maps of 1:50,000-1:200,000 scales

Additional layers may be included as well:
- Orthoimagery - Population Distribution Data - Detailed Administrative Borders

Regional Models may be integrated with 2D Urban ones to improve their accuracy in urban and suburban areas.
