SimActive Completes RADARSAT-2 Study for DSM Generation

May 30, 2012

SimActive Inc., is pleased to announce the completion of a study for the Centre for Topographic Information of Natural Resources Canada on digital surface model (DSM) generation from RADARSAT-2 imagery using Correlator3D™. The purpose of the project was to determine the maximum achievable accuracy over mixed terrain such as small vegetation, rocks, snow and ice.

The project involved processing an area of more than 5,500 km2 of RADARSAT-2 imagery at 1.6m ground sampling distance and generating a DSM with a 15m grid post spacing. The elevation data were compared against more than 6,000 ground control points from IceSAT and the RMS error was found to be less than 2.5m.

Despite the unique geometric and imaging properties of the RADARSAT-2 sensor, Correlator3D™ allowed for excellent autocorrelation.

“We were impressed by the high quality results generated from this satellite”, said Louis Simard, Chief Technology Officer of SimActive. “Despite the unique geometric and imaging properties of the RADARSAT-2 sensor, Correlator3D™ allowed for excellent autocorrelation”.
