The National Topographic Data Base (NTDB) comprises digital vector data sets that cover the entire Canadian landmass. Geomatics Canada has digitized and structured thousands of topographic maps, creating a complete and uniform product that can be highly useful in a broad range of industries. The NTDB includes features such as watercourses, urban areas, railways, roads, vegetation, and relief. The organizational unit for the NTDB is the National Topographic System (NTS), based on the North American Datum of 1983 (NAD83). Each file (data set) consists of one NTS unit at either the 1:50,000 or 1:250,000 scale. Furthermore, the data is now available by themes within a file. The ground data is depicted through points, lines, and areas.

Lakes 2M - 1:300k-1:3M scale (9)

The Atlas of Canada Base Maps provide coverage of the entire Canadian landmass. Data elements are feature coded and structurally clean. Base map components are available in five scales and a number of data exchange formats. The 1:2 million and 1:7.5 million scales are the primary bases for all Atlas products. The 1:30 million scale data have been generalized from the two larger scales. The data set covers: drainage (coastlines, rivers, lakes), boundaries (federal, provincial, district, dividing lines), transportation (primary and secondary highways, selected ferry routes, rail networks), populated places, national parks. Atlas information is two-dimensional layered vector data. Access to information regarding these datasets and the capability to download images and data files, free of charge, is available through http://geogratis.cgdi.gc.ca.

Lakes - 1:3M-1:10M scale (11)

This set of base maps was originally prepared in an analogue form for the production of the National Atlas 5th edition. They were used to overlay the thematic information used in the preparation of Atlas maps. The digital versions were derived from the original paper base maps in order to complete the 5th edition of the National Atlas.

The Atlas Frameworks are a set of integrated base map layers which form part of a larger National-Scale Frameworks data collection. These data have been compiled at a scale of 1:1 000 000 with the primary goal being to indicate correct relative positioning with other framework layers rather than absolute positional accuracy.

Hydrography Polygons (22)

This data is used to represent the outline of hydrography polygon features within each community of the Northwest Territories. It provides a base to be used for land management purposes in representing the waterbodies within the communities. This data set is not to be used for defining the exact location of hydrographical features; administrative decisions should be based on legal documents and legal survey plans. Hydrography Polygons: This data represents polygon features such as water bodies, intermittent lakes, foreshore flats, lagoons, reservoirs, dugouts, rivers, streams, sand bars, ditches, rapids, waterfalls, dams and marshes within each community of the Northwest Territories. The dataset is periodically updated on a community-wide scale. To see a current list of the last updates to all of the datasets see http://atlas.lands.gov.nt.ca/website/Atlas_Data_Updates.pdf.

Hydrography Point (24)

This data is used to represent the hydrography point features within each community of the Northwest Territories. It provides a base to be used for land management purposes in representing the waterbodies within the communities. This data set is not to be used for defining the exact location of hydrographical features; administrative decisions should be based on legal documents and legal survey plans. Hydrography Points: This data represents such point features as rocks protruding from the water within each community of the Northwest Territories. The dataset is periodically updated on a community-wide scale. To see a current list of the last updates to all of the datasets see http://atlas.lands.gov.nt.ca/website/Atlas_Data_Updates.pdf.
