Sample site locations downloaded from GPS. Some manual editing of locations made to place point firmly inside the appropriate harvest unit as determined from overlaying points on a DOQ.
Fairly accurate; data derived from GPS. Point data represent 2D sample sites. All sites located within recent clearcut harvest units.
Sample site locations recorded with GPS unit. Table created in MS Excel with UTM x-y coordinates of sites. Point shapefile created from table of coordinates.
Metadata imported.
