Enhanced City Packages

Within cities where broadband frequencies for wireless applications require a precise understanding of interference, 3D visualization becomes a significant tool. Enhanced City Packages are built for extremely detailed planning within city centers or city extents. The databases are produced from aerial stereo photo pairs, high-resolution satellite image stereo pairs or LIDAR data.

A standard package includes such datasets as:

• Digital Surface Model (DSM or Canopy DEM)
• Digital Elevation Model (DEM or DTM)
• 3D Buildings
• Clutter
• Building footprints
• Linear vector data including street vector
• Orthorectified image
• Text data

DEM: 1-5m resolution, extracted from 1:10,000 scale maps, satellite imagery or LIDAR data

DSM: 1-5m resolution, extracted from satellite imagery or LIDAR data

3D Buildings: extracted from satellite imagery or LIDAR data

CLUTTER: 5-meter resolution, extracted from 1:10,000 scale maps or satellite imagery, ten to fifteen classes, such as:

• Sparse Forest
• Dense Forest
• Wet Areas
• Low plantation
• Inland Water
• Park
• Open in Urban
• Semi Open Area
• Low Residential
• Dense Urban
• Urban
• Mean Urban
• Industrial area
• Airport

LINEAR VECTOR: extracted from 1:10,000 scale maps and satellite imagery, ten to twelve classes, such as:

• Highways
• Buildings
• Building blocks
• Major roads
• Streets
• Secondary roads
• Major railways
• Minor railways
• Airports
• Boundaries
• Rivers and lakes
• Coastline
