AVHRR Land Cover Data, Canada
Entry ID: Canada_GeoGratis_AVHRRLandCover


Summary
Abstract: This land cover data set was derived from the Advanced Very High Resolution
Radiometer (AVHRR) sensor operating on board the United States National Oceanic
and Atmospheric Administration (NOAA) satellites. Information on the NOAA
series of satellites can be found at
http://www.nrcan-rncan.gc.ca/com/index-eng.php .

The vegetation and land cover information set has been classified into twelve
categories. Information on the classification of the vegetation and land cover,
raster to vector conversion, generalization for cartographic presentations is
included in the paper "The Canada Vegetation and Land Cover: A Raster and
Vector Data Set for GIS Applications - Uses in Agriculture"
(http://geogratis.cgdi.gc.ca/download/landcover/scale/gis95ppr.pdf).

A soil quality evaluation was obtained by cross-referencing the AVHRR
information with Census of Agriculture records and biophysical (Soil Landscapes
of Canada) data and is also included in the above paper.

AVHRR Land Cover Data approximates a 1:2M scale and was done originally for
Agriculture Canada. The 1992 to 1993 coverages are broken down by provinces,
territories, and regions. Projection used is Lambert Conformal Conic (LCC)
49/77 with origin at 49N 95W.To promote geomatics use and education by
providing a web and file transfer protocol (ftp) site that distributes
geospatial data of Canada.
