The Landsat-7 National Imagery Coverage project has two objectives: to produce a national coverage of orthorectified Landsat-7 satellite images and database of ground control points, and to complete the geometric correction of non-precise digital files of the National Topographic Data Base (NTDB) in order to ensure the accurate overlaying of geospatial information. The availability of precise and geo-referenced Landsat coverage for all of Canada represents a critical source of digital data to support the strategic management of natural resources.

This project, co-funded by Natural Resources Canada's GeoConnections initiative, is being undertaken in partnership with more than 20 federal and provincial organizations. This is a unique initiative in the Canadian geomatics community because of the complete Canadian coverage and because of the extensive collaboration required at the federal and provincial levels.

Landsat-7 orthoimages are used in several applications, including the development of forestry regeneration inventories and monitoring systems, the classification of ecological districts, the calculation of land fragmentation and vegetation indexes, and the identification of landslide prone areas.

Some Landsat-7 products are already available to partner organizations and to the public through the GeoBase Portal, and more products will be made available as they are produced.

Project Priorities:

• Continue the production of Landsat-7 orthoimages
• Provide orthoimages to partners and make the geometric correction matrices and control point database available to clients
• Produce Radarsat-1 orthoimages to complete the coverage of Northern Canada where Landsat-7 data are not available
