New GeoBase data layers available
10 June 2009
Land Cover
The GeoBase Land Cover data layer is the result of collaborative work between Agriculture and Agri-Food Canada (AAFC), Natural Resources Canada (NRCan), the Canadian Space Agency and Canadian provinces and territories. Specific land classification processing was carried out by AAFC and NRCan’s Canadian Forest Service, Canada Centre for Remote Sensing, and Centre for Topographic Information – Sherbrooke.
This data is an integrated national layer built from various sources of classified land cover data. It is provided in vector format, derived from Landsat-5 and Landsat-7 satellite imagery collected between 1999 and 2003. It is downloadable in 1:250,000 scale tiles.
Aboriginal Lands
The addition of the Aboriginal Lands data layer to GeoBase has been achieved through collaborative effort between Natural Resources Canada’s Surveyor General Branch, the Centre for Topographic Information – Sherbrooke and GeoConnections. This data layer is one of several new administrative boundary data layers planned for inclusion in GeoBase.
Aboriginal Lands data depict the administrative boundaries of aboriginal reserves, settlement lands, and other lands as defined by a number of parliamentary acts. The data can be used to identify and locate Aboriginal lands within Canada, position them relative to one other, and determine their respective sizes. This data is a primary reference for many federal and provincial government departments and agencies.
The Aboriginal Lands data is updated monthly to reflect additions and other changes in aboriginal lands. It is important to note that the data is a representation only and cannot be used to define boundaries. Such definitions must be based on legal documents and official survey plans.
Aboriginal Lands data can be downloaded in 14 data sets – by province or territory or for all of Canada. It replaces the corresponding Canada Lands Administrative Boundary (CLAB) which has been available on the GeoGratis web site.
