RADARSAT-1 Orthorectified Imagery

Description

The 5 RADARSAT-1 images (processed and distributed by RADARSAT International (RSI), a subsidiary of MDA Geospatial Services Inc.) complete the landsat 7 orthoimagery coverage.

RADARSAT-1 orthoimages are stored as raster data produced from SAR Standard 7 (S7) beam mode with a pixel size of 15 m. They have been produced in accordance with NAD83 (North American Datum of 1983) using the Universal Transverse Mercator (UTM) projection. RADARSAT-1 orthoimagery were produced with the 1:250,000 Canadian Digital Elevation Data (CDED) and photogrammetric control points generated from the Aerial Survey Data Base (ASDB).

The objective of GeoBase is to produce a complete set of cloud-free (less than 10%) orthoimages covering the Canadian landmass using Enhanced Thematic Mapper (ETM+) data from the Landsat 7 satellite and to use Radarsat-1 data where Landsat7 data is unavailable.
