How does ArcGIS geoprocessing tool polygon neighbors work?
How the ArcGIS geoprocessing tool Polygon Neighbors finds neighbors and populates the output table. The neighboring relationships are defined as follows: Overlapping neighbors—polygons that have all or part of their areas overlapping Edge neighbors—polygons that have common or touching boundaries
How to calculate the area of a polygon?
The detailed workflow is as follows: Select a polygon to use as the source feature. Find all the polygons that intersect the source polygon (find the neighbors). Add the AREA field to the output table. Calculate the area of the overlap. Record the calculated area for use in the output table AREA field.
How do you find the neighbors of a polygon?
Find all the polygons that intersect the source polygon (find the neighbors). Add the AREA field to the output table. Calculate the area of the overlap. Record the calculated area for use in the output table AREA field. Record 0 for use in the output table LENGTH field.
How are edges of polygons found in ArcGIS?
Edge neighbors—polygons that have common or touching boundaries Node neighbors—polygons that touch at a point (boundary crossing or touching) Neighboring polygons are found according to the same rules for polygons as the Intersect tool. The following discussion assumes use of the tool dialog box.
Can you get a polygon of the outer boundary?
This will give you a polygon of the outer boundaries but remove the inner boundaries. You will have to merge the feature groups tho, first. Then the clip will give that feature minus the inner boundaries.
How can I increase the size of my polygons?
Available with Production Mapping license. 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. This tool modifies the input data.
