Description:
Abstract:
This data set is a 1991 era forest canopy map for Coastal Washington. This map is derived from the 1991 land cover map. Forest categories (Deciduous, Mixed, Evergreen, and Palustrine Forest) have been coded to value 1. All other land cover categories were coded to 0. Forest is defined as areas of woody vegetation greater than or equal 5 meters tall and having greater than or equal to 40 percent canopy cover.
Purpose:
To improve the understanding of water quality issues by assessing changes in forest canopy between 1991 and 2001
Supplemental_Information: Similar data sets occur for 1996 and 2001.

Process_Description:
The 1991 land cover map was developed by using the 1996 land cover map as a base. The 1996 land cover map was obtained from National Oceanographic and Atmospheric Administration (NOAA) Coastal Services Center (CSC)/Coastal Change Analysis Program (C-CAP). A change analsis was performed between the 1991 imagery and the 1996 imagery to identify areas that had changed. The portion of the imagery that had changed was classified into the 19 non-developed land cover classes. The 1991 classified change areas were combined with the unchanged areas from the 1996 map (which included the developed classes) to produce a wall to wall classification for 1991. The 1991 land cover map was coded into a binary map. Forest classes (Deciduous, Mixed, Evergreen, and Palustrine Forest) were coded to value 1 and all other classes were coded to value 0.
