Process_Step:

Process_Description:

The number and distribution of sampling points was determined according to the USGS/NPS Vegetation Mapping protocols. A stratified random sampling approach was used, distributing the sampling effort across the seven vegetation associations. Due to the small size of Johnstown Flood National Memorial and the limited number of polygons, a census of the vegetation map was attempted. Thirty-four of the 36 polygons attributed with vegetation association names were sampled; two polygons that were excluded from sampling to due their small size. 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 600 sets of random x,y coordinates that fell within the boundaries of Johnstown Flood National Memorial. These coordinates were imported into ArcView 3.2 and overlain 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 August and September 2004.
