The input feature layer that contains the data to be extracted.

Feature Layer
OverlayLayer

The overlay layer that inherits the data.

Feature Layer
SelectedSummarizations
[SelectedSummarization,...,...]

The variable from the input layer on which to run the spatial overlay.

String
OutputFeatureClass

The feature class that will contain the overlay features.

Feature Class
SpatialOverlayAppendData
(Facultatif)

  • TRUEAppends data to layer.
  • FALSEWill not append data to layer. This is the default.
