The digital Surface Model, DSM, is a database representing the location, elevation and shape of built up features and vegetation from the ground surface. The DSM is produced by utilization of an automated process based on stereo information from satellites or airborne sensors. The DSM provides up-to-date information enabling the RF planners to:
• Position base stations and antennas in an optimal way
• Check for interference between beams
• Simulate line of sight connections
