Land Cover, Circa 2000 (landcover:csc2000)

Land Cover information is the result of vectorization of raster thematic data originating from classified Landsat 5 and Landsat 7 ortho-images, for agricultural and forest areas of Canada, and for Northern Territories. The forest cover was produced by the Earth Observation for Sustainable Development (EOSD) project, an initiative of the Canadian Forest Service (CFS) with the collaboration of the Canadian Space Agency (CSA) and in partnership with the provincial and territorial governments. The agricultural coverage is produced by the National Land and Water Information Service (NLWIS) of Agriculture and Agri-Food Canada (AAFC). Northern Territories land cover was realized by the Canadian Centre of Remote Sensing (CCRS). Land Cover data are classified according to a harmonized legend build from the partners legends.

CanImage, natural colours composite (bands 3-2-1) (imagery:landsat7)

CanImage is a raster image containing information from Landsat 7 orthoimages that have been resampled and based on the National Topographic System (NTS) at the 1:50 000 scale. The maximal resolution of this layer is about 15 metres. The original source of Landsat 7 ortho images contain 8 spectral bands. For the creation of the CanImage layer, the following bands were retained and combined: band 3 (red), 2 (green) and 1 (green-blue). These bands are displayed using the colors: red (band 3), green (band 2) and blue (band 1). A linear stretching was also performed on each of individual band in order to increase the contrast.

NHN Hydrography (nhn:hydrography)

The National Hydro Network (NHN) focuses on providing a quality geometric description and a set of basic attributes describing Canada's inland surface waters. It provides geospatial digital data compliant with the NHN Standard such as lakes, reservoirs, watercourses (rivers and streams), canals, islands, drainage linear network, toponyms or geographical names, constructions and obstacles related to surface waters, etc. The best available federal and provincial data are used for its production, which is done jointly by the federal and interested provincial and territorial partners.

Boundaries of Drainage Areas (nhn:drainageareas)

Canadian territory subdivision used to manage and distribute NHN data. NHN Work Units limits generally correspond to the Water Survey of Canada Sub-Sub-Drainage Areas, to the Fundamental Drainage Areas from the Atlas of Canada, or to specific delimitations originating from a federal, provincial or territorial partner.

Boundaries of NHN Work Unit (nhn:drainageareas:nhnda)

The original NHN Work Unit Limits were created based on the Water Survey of Canada Sub-Sub-Drainage Areas (WSCSSDA) and Fundamental Drainage Areas (FDA) from the Atlas of Canada. They are being modified and refined as better provincial source data is brought into the data production process following NHN partnerships between federal and provincial/territorial agencies.

Boundaries of Secondary Drainage Areas from Water Survey of Canada (nhn:drainageareas:wscsda)

In the drainage area classification of Version 5.0 of the WSC dataset from the National Scale Frameworks Hydrology - Drainage Areas, Canada has 164 sub-drainage areas.

Boundaries of Major Drainage Areas from Water Survey of Canada (nhn:drainageareas:wscmda)

In the drainage area classification of Version 5.0 of the WSC dataset from the National Scale Frameworks Hydrology - Drainage Areas, Canada has eleven major drainage areas.

Names of Major Drainage Areas from Water Survey of Canada (nhn:drainageareas:wscmda_names)

The first 2 characters of the name of the Work unit RHN correspond to the WSCSSDA codes. They represent the 11 drainage areas of Canada (ex: 08).

Names of Secondary Drainage Areas from Water Survey of Canada (nhn:drainageareas:wscsda_names)

The first 3 characters of the name of the Work unit RHN correspond to the WSCSSDA codes. They represent the 164 sub-drainage areas of Canada (ex: 08G).

Names of NHN Work Units (nhn:drainageareas:nhnda_names)

The NHN Work Unit nomenclature is composed of 7 characters. The first 4 correspond to the WSCSSDA codes. The next 3 are used when the NHN Work Unit limit differs considerably from the original WSCSSDA limit (these characters bear the value '0' when not used).
