Aggregate Polygons (Coverage)

This tool only works with an ArcInfo license and will only be available in ArcToolbox if you have installed ArcInfo Workstation.

Combines disjoint and adjacent polygons into new area features based on a distance.

Parameter Explanation Datatype
Input Coverage (Required)

The coverage containing polygons to be aggregated.

Output Coverage (Required)

The output coverage containing aggregated features as preliminary regions with a subclass AREAAGG. The output coverage name must be different from the input coverage name.

Cell Size (Required)

Sets cell size in coverage units for grid conversion. Cell size must be greater than 0.

Aggregation Distance (Required)

Sets the aggregation distance in coverage units. A distance must be equal to or greater than the cell size.

Preserve orthogonal shape (Optional)

Specifies the characteristic of the input features that will be preserved when constructing the aggregated boundaries.

  • NON_ORTHOGONAL—Specifies natural features, such as vegetation or soil polygons, which unlikely contain orthogonal shapes. This is the default.
  • ORTHOGONAL—Specifies building-like features for which orthogonal shapes will be preserved and constructed.

gp = arcgisscripting.create()

gp.workspace = "h:\\workspace"
gp.toolbox = "arc"
gp.aggregatepolygons("trees", "vegetation", 10, 150)
