MergeAggregate

Disponible con licencia de Production Mapping.

Resumen

Merges polygon features based on a specified distance and field values.

Debate

This generalization function can be used to aggregate polygon features for purposes such as meeting the minimum size for polygon features for a product specification or for annotating large multipart features. For example, the layer that contains the merged features can be used to annotate a campus composed of several buildings.
