Data sets
ALL MODELS DATASETS CONSIST OF THE FOLLOWING ININTEGRATED LAYERS: UP-TO-DATE AND HIGHLY ACCURATE TERRAIN (DTM/DEM), CLUTTER, VECTORS, TEXT LABELS, BUILDING HEIGHT MODEL, ORTHOIMAGERY 1. DTM/DEM DTM (Digital Terrain Model) - represents the elevations of ground surface, location and shape of obstacles to wave propagation. DEM (Digital Elevation Model) - describes terrain elevation that is merged with building and vegetation heights. Parameters of DTM/DEM depending on model, source materials and relief complexity: • Resolution: 5/10/20/50/100 m • Vertical accuracy (heights): 2-50 m • Planimetric accuracy: 2-80 m 2. CLUTTER/LAND USE MODELS Clutters describe the surface and built-up features which influence on radio wave propagation. They are classified into different classes: classes of built-up areas, water classes, classes of landscape and vegetation. We usually offer: • for regional model – 11 classes • for city model – 13-16 classes • for microplanning – 16-20 classes Parameters of clutter models: • Resolution 5/10/20/50/100 m • Planimetric accuracy: 2-50 m 3. VECTOR/LINEAR OBJECTS Vector data consists of the transportation network and other linear features of the map such as coastlines, rivers etc. We offer 9 vector classes: HIGHWAYS, STREETS, MAJOR ROADS, SECONDARY ROADS, COASTLINE, BOUNDARIES, AIRPORTS, RAILWAYS, WATER FEATURES Parameters of vector models: • Planimetric accuracy: 2-50 m 4. TEXT LABELS Text labels on the map can be prepared according to your requirements We usually offer the next set of text labels: CITIES, TOWNS, VILLAGES, RAILWAY STATIONS, WATER FEATURES 5. BACKGROUND RASTER Mosaic of scanned topographic maps or satellite images can be prepared by your order. Parameters: • Resolution 5/10/20/50/100 m • Planimetric accuracy: 2-50 m Satellite images Landsat7, SPOT, IRS, Aster, QuickBird, EROS, IKONOS, OrbView can be used 6. BUILDING HEIGHT MODEL Vector database represents the outline of built-up structures (buildings, bridges, towers and other obstacles) with attributive information of relative or absolute height of every object. Parameters: • Resolution: 2 m or 5 m • Planimetric accuracy: 2-5 m • Vertical accuracy (heights): 1-5 m • Buildings model accuracy (heights): 2/3/5/10 m • Format raster and/or vector Data can be converted into any RF-planning system format Vectors and clutter classes can be organized according to your requirements
