- Process_Description:
-
The USGS/NPS Vegetation Mapping Program protocols were followed to assess the thematic accuracy of the Friendship Hill National Historic Site vegetation map. A stratified random sampling approach was used, distributing the sampling effort across seven vegetation associations. Polygons labeled with modified Anderson level II categories and the polygons representing managed grasslands were not included in the thematic accuracy assessment sampling. The number of samples per association varied according to the rarity of the vegetation type, both in terms of number of polygons and polygon size. The distribution of sampling points among vegetation types was adjusted slightly from that recommended by the protocol to fit park-specific conditions. In general, the adjustments tended to weight the area covered by an association more heavily than the number of polygons contained in that association.
In order to randomly determine the location of these sampling points in the polygons, the random number generator function in Microsoft Excel was used to create 900 sets of random x,y coordinates that fell within the boundaries of Friendship Hill National Historic Site. These coordinates were imported into ArcView 3.2 and overlaid onto the vegetation map. The first pair of coordinates listed in the table of coordinates to fall within a polygon at least 50 m from the polygon boundary was selected. All other points that fell within that polygon were deleted. This procedure was carried out until all points were assigned.
Each accuracy assessment point was then located in the field using a Trimble Geo XM GPS unit during May and June 2005.
