Process_Step:
Process_Description:
Individual polygons were drawn around the extent of each of the 36 individual mosaics used to compile the 250 m COW GLORIA composite mosaic. Boundaries were checked against the georeference reports to verify the boundaries. When complete the polygons were completed, the attribute mosaic was added and the individual mosaics were numbered. The final vector data layer was exported from the PCI Remote Sensing file in shapefile format.
