Raster Topographic Maps
A raster map is a digital image or bitmap that is made up of a grid of pixels. The B.C. Government provides raster base maps in three different scales. The topographic map data used to create the digital raster maps is derived from varying data sources.
Product Details
Raster topographic maps are available in three scales: 1:20,000, 1:250,000 and 1:2,000,000.
Specifications
1:20,000 Raster Topographic Map
The 1:20,000 scale digital raster topographic maps are derived from Terrain Resource Information Management (TRIM) 1:20,000 topographic data. As TRIM files are updated, so are the corresponding raster topographic maps.
The Province of B.C. is covered by 7027 of these map sheets. The base maps depict roads, streams, lakes, wetlands, glaciers, coastlines and other features in colour against the greyscale background, which may appear pixelated when zoomed in.

The 1:250,000 scale digital raster topographic maps are derived from the 1:250,000 Canadian National Topographic System (NTS) base maps. They were produced by scanning layers of the federal paper map series.
The Province of B.C. is covered by 89 of these map sheets. With an appearance similar to the 1:20,000 series of maps, the 1:250,000 raster topographic maps are appropriate where a higher level, less detailed view is required.
