How is a source polygon related to a neighbor polygon?
The tool analyzes polygon contiguity, summarizing the between source polygons and neighbor polygons. The summary information is written to an output table. A source polygon may have one or more neighbor polygons; a neighbor polygon is spatially related with the source polygon in at least one of the above ways.
How does the polygon neighbors tool in ArcGIS work?
The Polygon Neighbors tool follows a hierarchical path to determine the type of neighbor and the statistics to record in the output table. The neighboring relationships, in hierarchical order from high to low, are overlapping, coincident edge, and node neighbors.
Are there second order contiguity for ArcGIS neighbors?
Only first-order contiguity is analyzed and reported by the tool; relationships beyond that are not examined; that is, neighbors of neighbors (second-order contiguity) are not examined.
When to use include area overlap in polygon neighbors?
If the specified fields identify unique polygon groups, the neighboring information is summarized and reported by the groups. See How Polygon Neighbors works for details on the use of this parameter. Include area overlap can be used if you want area overlapping relationships to be analyzed.
How does the Intersect tool work with Polygon neighbors?
Overlapping neighbors—polygons that have all or part of their areas overlapping 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.
How is the edge neighbor analysis done in ArcGIS?
Edge neighbor analysis is complete. Analyze the next neighbor polygon. Find the number of times the neighbor polygon crosses and touches the source polygon at a point. Record this count value for use in the NODE_COUNT field.
