An overview of the Layer Snapshot toolset

The Layer Snapshot toolset provides tools to identify shape and symbology modifications within a feature class. Use these tools to identify features that have changed across editions of a map or chart.



Calculate Layer Snapshot

Calculates a snapshot of a feature layer by creating a snapshot value of feature geometry, extent, and symbology. The tool stores the snapshot value in a long integer field in the Input Features feature class. The Compare Layer To Snapshot tool uses the snapshot value to identify changes to geometry, extent, and symbology in a layer across multiple map documents.

Compare Layer To Snapshot

This tool, in conjunction with Calculate Layer Snapshot, selects features that have had geometry, extent, or symbology changes.
