Toolset Requirements

In order to run the tool successfully the data must be stored in a file geodatabase in the correct data schema and include a project area boundary. This area should be a polygon that exactly defines the geographic areas that have been mapped. There is no limitation to what this boundary can be. Common examples include; watershed, county, quadrangle, township, parcel, refuge, or state wetland area. An example file geodatabase in the wetlands database schema is included in the toolset download.
