Aggregate Points (Cartography)

ArcGIS Pro 3.4 | | Help archive

Summary

Creates polygon features around clusters of proximate point features.

Usage

  • Polygons are created around clusters of three or more points within the aggregation distance.

  • A one-to-many relationship table—named the same as the output feature class appended with _Tbl—will be created that links the aggregated polygons to their source point features. This table is in the same location as the output feature class and contains two fields, OUTPUT_FID and INPUT_FID, storing the aggregated feature IDs and their source feature IDs, respectively. The link can become incorrect when any of the input or output features are modified. With this table, you can derive necessary attributes for the output features from their source features using appropriate geoprocessing tools.

  • Point aggregation may introduce polygon holes or areas where adjacent polygon boundaries meet at one vertex.
