A priority of the Canadian Forest Service and Canadian Space
			Agency joint project, Earth Observation for Sustainable Development
			of Forests (EOSD) is the production of a land cover map of the
			forested area of Canada.  The land cover map will be based on
			Landsat 7 Enhanced Thematic Mapper (ETM+) data and represent circa
			year 2000 conditions.  Land cover will be produced through a
			partnership of federal, provincial, and territorial governments,
			universities and industry.  Products generated will follow the
			1:250,000 National Topographic Series Map Sheet tiles and naming
			convention.  The land cover products are expected to be completed
			by early 2006.
		Purpose: 
			A mosaic of Canada was generated to assist in EOSD planning 
			and carbon accounting studies.  This image mosaic of Canada
			consists of images from circa year 1990.  The image consists of Landsat
			Band 7 (Red), Band 4 (Green), and Band 2 (Blue). 
		Supplemental_Information:            
			A mosaicked image of Canada was created using MrSID 5 x 6 degree
			tiles initially generated by Earthsat using circa 1990 Landsat imagery.  The generation
			of the MRSID files was supported by a scientific data purchase program funded
			by NASA's Earth Science Enterprise Program (http://www.esad.ssc.nasa.gov/).  
			
			To generate this product, compressed MrSID image files were uncompressed, 
			converted to ERMapper ERS files, reprojected, mosaicked (including blending 
			or feathering) and then saved as an ER Mapper ECW compressed file using a
			25:1 compression ratio.  The original uncompressed mosaic file of Canada was 85 GB. 
			
			Tiled images were reprojected from a Transverse Mercator (UTM) to a Lambert 
			Conformal Conic projection and mosaicked by the Natural Resources Canada - 
			Canadian Forest Service.  Radiometrically balancing was applied to the 
			individual tiles. Scenes within the tiles may not be properly balanced 
			due to different scene dates.  Also note that this file is best used 
			as a visualization tool and is not intended to be used for 
			scientific analysis. 
			
			This product was generated by the Earth Observation for Sustainable Development 
			of Forests (EOSD) Initiative, a partnership between the Canadian Forest Service 
			(www.nrcan.gc.ca/cfs-scf/) and the Canadian Space Agency (www.space.gc.ca/asc/index.html).  
			More information on EOSD can be found at www.pfc.cfs.nrcan.gc.ca/eosd/
			
			You can view this product with a free viewer called ER Viewer (available 
			at www.ermapper.com). This site also has other free software to load this 
			product into various GIS products.  A lower resolution mosaic of Canada is available
			in geotiff format at http://www.pfc.cfs.nrcan.gc.ca/eosd/resources/images_e.html or

			Known issues include
			1.  ArcGIS - ArcView will lose spatial information.  
			a) Either load a vector file and set the projection to match that specified 
			above or preset the coordinate space for the layers to match the projection 
			information listed above. The mosaic should then be geo-referenced in the 
			correct location.  
			
			b) There are two methods to work around this issue.
			i. You can also insert the following projection information in the directory you
			installed the ECW plugin: 
			(eg. \Earth Resource Mapping\ArcGIS Plug-in with ECW Compressor\ER Mapper Runtime\GDT_DATA)
			
			This may or may not correct the problem but this information can be useful if 
			you are using ER Mapper (files are also located in the ERMAPPER\GDT_DATA 
			directory)
			 
			ii.  In file lamcon2.dat insert
			
			L2CAN83, 0.0, 0.0, 0.0, 0.0, 1.0, -1.658062789, 0.855211333, 1.343903524, 0.0, 1, 0.0, 0.0, 0.0, 6378137.0, 0.0818191908375549, 298.257221, 1
			
			iii.  In file project.dat insert
			
			L2CAN83, lamcon2, 1,6378137.0, 0.0818191908375549, 298.257221, 1
			
			iv.  In file projinst.dat insert
			
			L2CAN83,lamcon2,1,1,1,01_lamcon2,CANADA,,LCC proj for Canada,WORLD,PUBLIC
			
			Make sure there are no DOS Carriage returns otherwise it might not work.  Also
			be sure to restart ER Mapper if you are modifying the files is the GDT_DATA 
			directory.
			
			2.  The .ers file will not be recognized if used with a .ecw file in ARCGIS.
			
			3. If you load the file into ER Mapper, you should remove the .bak from the 
			.ers file.
