CANADA LAND INVENTORY LEVEL I LAT/LON DIGITAL DATA SOIL CAPABILITY FOR AGRICULTURE 1. Coverage Specifications Original Map Scale: 1:50,000 Resolution : .000061035 of a degree Map Projection : None, i.e. latitude/longitude co-ordinates Datum : NAD27 Spheroid : Clarke 1866 Units of Measure : decimal degrees 2. CLI Level I Latitude/Longitude Digital Data CLI Level I latitude/longitude digital data are intended for GIS users who wish to integrate CLI thematic data with their own topological base maps, i.e. for GIS users who wish to "cookie-cut" the CLI thematic layers with their own topological shoreline layer. CLI Level I thematic data is intentionally extended past the shoreline and as such does not contain the proper definition of shoreline. The data are not projected and co-ordinates, areas and perimeters are in decimal degrees. DO NOT ATTEMPT TO DERIVE AREA STATISTICS FROM THESE DATA UNTIL THEY ARE INTEGRATED WITH A PROPER SHORELINE AND THE RESULTS PROJECTED TO A SUITABLE MAP PROJECTION. If the above restrictions do not meet your GIS objectives, obtain the equivalent Level II UTM data with integrated base map from the same distribution source.
