3.3.2.3 Earth Observation for Sustainable Development of Forests
Figure 3-2. EOSD Land Cover Classification
The Earth Observation for Sustainable Development of Forests (EOSD) is a land cover
classification consisting of 23 vegetation (Figure 3-2), and other cover type classes based on
year 2000, 30-meter Landsat satellite imagery. EOSD data were downloaded from the
Canadian Forest Service‟s CFSNet website 14 and reviewed to ensure complete watershed
coverage of the data. Upon review, a few areas were found to be missing data (“NoData” pixel
values). Personal correspondence with Chris West of the Natural Resources Canada,
Canadian Forest Service verified the issue and provided only a partial solution in some areas. In
the areas with unclassified pixels, no change detection was able to be reported.
All EOSD raster images were combined into a single mosaic and clipped to the watershed
boundaries. An additional buffer was applied to the previously buffered watershed boundaries
to make certain all data was captured for this process. Upon review of the data, it was found
that there were spatial shifts in the southeastern watershed study areas. To address this issue,
a mosaic raster dataset was created for all areas where spatial shifts did not exist to hold their
positions constant. A subset of the larger EOSD data was then created for the shifted areas,
and the ArcMap Georeferencing tool was utilized to register the EOSD data to the spatial
