Increase Polygon Area (Production Mapping)
Increases the areas of polygons until they meet a minimum size or larger. You can optionally limit the features to be enlarged based on whether they intersect another feature class.
A warning is raised if the input features are not in a projected coordinate system. This tool relies on linear distance units, which will create unexpected results in an unprojected coordinate system. It is strongly suggested that you run this tool on data in a projected coordinate system to ensure valid results. An error is raised and the tool will not process if the coordinate system is missing or unknown.
This tool cannot be run on data that is registered as versioned.
Features are enlarged in all directions by applying a small buffer iteratively until the feature is larger than the minimum size. The resulting geometry will be larger than the minimum size and not equal to it.
If this tool is run in an edit session in ArcMap, you can stop the edit session without saving changes to restore features that have been deleted.
The polygon features to be enlarged.
The minimum area that features must meet.
The buffer value by which the area is increased for each feature. The buffer is applied until the feature reaches the minimum size.
The feature class that intersects the input polygons. Input polygons that intersect are enlarged.
The feature class whose features serve as a boundary for the polygon features when they are enlarged. This ensures that the features do not cross a barrier when they are enlarged; for instance, a pond does not cross a road.
This sample script increases the area of parks until they are a minimum of 1,000 square feet.
