How Spatial Overlay works

Иллюстрация

Использование

• The input layer must be properly formatted using the Analysis Layer Setup tool in Business Analyst with appropriate apportionment values applied.

• The input layer contains the underlying data you want to extract.

• Data is added to the overlay layer. Data is extracted from the input layer and aggregated into the overlay layer.

• You can aggregate from a point- or polygon-based input layer.

• A file called Ratios Table.dbf will be created and added in the same directory of the output overlay layer. This ratios table contains the percentage of intersection and weights used to execute the overlay.

• Do not run a spatial overlay analysis if ArcMap is still redrawing your map. This may cause a problem with ArcMap and result in ArcMap crashing.

Параметр	Объяснение	Тип данных
OverlayLayer	The input feature layer that contains the data to be extracted.	Feature Layer
SelectedSummarizations [SelectedSummarization,...,...]	The overlay layer that inherits the data.	String
OutputFeatureClass	The variable from the input layer on which to run the spatial overlay.	Feature Class
SpatialOverlayAppendData (Дополнительный)	The feature class that will contain the overlay features. TRUE —Generates a spatial overlay on selected boundaries. FALSE —Generates a spatial overlay on all boundaries. This is the default.	Boolean
UseSelectedFeatures (Дополнительный)	The selected variables that will be appended to the overlay feature. TRUE — Appends data to layer. FALSE —Will not append data to layer. This is the default.	Boolean
SelectedDCs [SelectedDCs,...,...] (Дополнительный)	The online feature service from which you will append variables.	String
