National Topographic System 1:250,000 Base Map
The B.C. Government has produced a 1:250,000 scale base map of the province, based on the Canadian National Topographic System (NTS) topographical maps. This vector map product was developed by scanning and restructuring various lithographic layers of the federal paper map series.
