2001. Telecom
SPATIAL DATA BASES
for the planning of the mobile telephone units
for Telecom Serbia Ltd.
Project task:
• Digital terrain model (DTM)
• Digital orthophoto
• Raster data base on building heights
• Raster data base for “Clutters”
(“Land Use Map” – LUM, “Clutter maps”)
• Vector data base of waterways and
transportation network – (“Linear features” - LIN)
