I am working with a polygon layer of forest age data (one shapefile with many features representing forest stands of different ages) trying to identify places where forest stands in 5 different age classes meet to make grouse habitat management decisions. It would be helpful to automatically generate points where these specified stand boundaries meet. Any suggestions? Thanks!
The following model performs the following workflow to accomplish your goals:
Optional secondary model
To recap visually:
Buffer the forest stands polygons. In this case, I buffered 10m.
Convert buffered polygons to raster and caclulate "unique values" statistics
Reclassify so that 0 - 4 = 0 and >= 5 = 1
From the optional secondary model, convert raster "hotspots" to polygons and calculate the mean center of each polygon. These are the areas where 5 or more unique forest stands meet.
Rather than use Select by Location, how about using the Intersect geoprocessing tool and setting the Output Type parameter to POINT?
From the ArcGIS help.
A very simple way to do this is:
Looking at the count field from the joined summary table you will be able to identify those instances where 5 polygon vertices touch.
