Overview
Crown Registry and Geographic Base provides raster base maps in three different scales:
- Raster Base Map 1:20 000
The 1:20 000 digital Raster Base Maps are derived from TRIM 1:20 000 topographic data. There are 7027 maps that cover the province of BC and they are available in both Albers and UTM projections in geoTIFF format for a variety of uses in digital applications. A version in PDF format in the UTM projection is also available; it is appropriate for 1:20 000 scale paper map production.
The maps are intended to be attractive and easily understood with roads, streams, lakes, wetlands, glaciers, coastlines and other features depicted in colour against a shaded relief, greyscale background representing the shape of the surface. The pixel size of 2 metres provides high accuracy for the features shown. The greyscale background is based on a 25 metre grid and will appear somewhat pixelated when zoomed in. As TRIM files are updated, so are their corresponding Raster Base Maps. - Raster Base Map 1:250 000
The 1:250 000 digital Raster Base Maps are derived from the 1:250 000 Federal Base Maps, which were produced by scanning various lithographic layers of the published paper map series. These maps are also available in both Albers and UTM projections in the geoTIFF format and in UTM only in the PDF format. With an appearance much the same as the 1:20 000 series maps, they are appropriate where a higher level, less detailed view is required. The Province is covered by 89 of these sheets. These maps are based on a pixel size of 10 metres, with the shaded relief, greyscale background from the same 25 metre grid as the 1:20 000 series. - Raster Base Map 1:2 000 000
Derived from various provincial sources, a single 1:2 000 000 Raster Base Map is also available. The roads and place names are from 2006 and are updated annually. A 100 metre pixel size is used for the map detail, which is presented against a shaded relief, greyscale background derived from a 200 metre elevation grid.
Raster Base Maps are produced by the Base Mapping program area.
