The Canada Centre for Remote Sensing (CCRS), and the Canadian Space Agency (CSA) have collaborated with contributions from RADARSAT International (RSI) (now MDA Geospatial Services Inc. (MDA GSI)), to create an ortho-rectified RADARSAT-1 mosaic of Canada. Using CSA's RADARSAT data archive, ScanSAR Narrow B descending mode data were selected. The majority of the data, south of 60 degrees was acquired during the growing seasons of 1998 and 1999. The remaining data were collected during the winters of 1998 and 1999. A digital provincial mosaic has been produced at a 100m pixel spacing, in a NRCan Lambert Conformal Conic (NRLCC) projection. Projection : Lambert Conformal Conic Datum - Ellipsoid : NAD 83 True origin : 95°00'00.0000W 49d00'00.0000N 1st std parallel : 49°00'00.0000N 2nd std parallel : 77°00'00.0000N Pixel Size (m) : 100.0 E 100.0 N.
