Expression Explanation
Function Name PolygonAdjacency
<input dataset> A String representing the input layer. Must be of Polygon type.
<output dataset> A String - the full name of the output layer.
{Link Field} A Double representing the Generalization tolerance (in the units of the spatial reference of the input layer.

Running the function

ETGWPath used in the table below is the  full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETGeo Wizards\ETGWRun.exe")
