This cartographic quality series of 1: 250 000 scale colour maps covers the provincial extent of Alberta and is comprised of 50 maps that are individually named using the National Topographic System (NTS) map sheet identifier. These maps display the Alberta Township System (ATS), contours (50m intervals), major hydrographic features, municipalities, major roads (Note: No updated roads in 83D Canoe River and 84O Whitesand River mapsheets), railways, select geo-administrative features (parks, reserves, etc.). At this scale 1.0 cm on the map represents 2.5 km on the ground. Each map covers an area of 2.0 degrees longitude by 1.0 degree latitude. This product can be viewed on a computer, printed or be plotted in part or in whole. The update of this map series is based on the provincial Base Features Access Update Program that has an approximate 5 year update cycle.
