Grassy Island Lake, Alberta - Boundary (GIS data, polygon features)

Author(s) Alberta Environment Date 2008-12-08

All available bathymetry and related information for Grassy Island Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.
