Description :
The provincial wetland (status quo) maps of the Prairie Pothole Region, Central Canada, do not adequately depict wetland resources and properties. This study integrates LANDSAT Enhanced Thematic Mapper Plus ETM+, RADARSAT-1 Synthetic Aperture Radar (SAR), and LIght Detection And Ranging (LIDAR) data, taking advantage of the synergy in their integration. This integrated approach increases in the size of wet areas and pond densities. The improved mapping capability is attributed to a combinatory power of the integrated approach in detecting small, transient and saturated wet areas.
