Percent Edge Tool

The Percent Edge Tool is an ArcMap tool. The Percent Edge Tool performs the following calculations for each polygon in a polygonal GIS layer: area, compactness, perimeter, edge lengths with adjacent polygons, and percentage of edge with adjacent polygons. This information can then be summarized into a pivot table and queried.

A Tool for Prioritizing Management Units at Morris Wetland Management District

Where are most important places to direct conservation effort? Such a simple question is not answered simply. There are a myriad of priorities, constraints, and capacities, both scientific and socio-economic, which in combination guide the allocation of management effort. An honest accounting of these priorities, constraints, and capacities is essential for efficient, effective action.

Split By Attribute Tool

  • The Split By Attribute Tool is a customization of ArcMap.
  • The tool takes a single shapefile and splits it into many shapefiles based on the unique values of a chosen field.
  • If the user has made a selection on a shapefile, then only those features that have been selected will be split.
  • Each output layer will named with the following structure: user supplied base
