Generate Geographies From Overlay (Business Analyst)

Disponible con licencia de Business Analyst.

Resumen

Generates trade areas from the features of an input standard geography level that has a specified spatial relationship with the input.

Uso

• The tool finds the component geography of the given input layer and, for each component geography, calculates how much of its area, population, number of households, and so on, intersect the input feature.

• The Input Features parameter value is used to define which features of the standard geography level layer will be included in the output.

• The Input Features parameter value can be a point or polygon feature type.

• The layer output is based on a polygon-to-polygon selection and is computed by a geometric relationship of the features in both polygon-based layers.

• The All ratios option for the Ratio parameter is not available when using online data.

• This tool will consume credits under certain circumstances, for example, if one or more Ratios value variables are selected and are connected to ArcGIS Online, there will be a credit consumption similar to the Enrich Layer tool. Credit consumption also depends on the number of partial intersections between the Input Features and Geography Level inputs.

Parámetros

Cuadro de diálogo

Etiqueta	Explicación	Tipo de datos
Geography Level	The geography level that will be used to define the trade area.	String
Input Features	The features that will be used to extract the standard geography level features by the specified spatial relationship. It can be either all features from the layer or only those selected once a selection is available.	Feature Layer
ID Field	The field that will be used to identify the Input Features parameter value—for example, the IDs of drive time polygons.	Field
Output Feature Class	The output feature containing the trade area.	Feature Class
Relationship (Opcional)	Specifies how the subgeography will be selected from the boundary layer. Intersect—If any of the subgeography features touch or intersect the boundary layer, they will be included in the output layer. This is the default. Have their center in—If the centroids of any of the subgeography features are contained within the boundary layer, they will be included in the output layer. Completely within—Only the features of the subgeography layer that are completely contained within the boundary layer will be included in the output layer.	String
Ratios (Opcional)	Specifies the ratios that will be calculated. No ratios—No ratios will be calculated. This is the default. Area only—Only the ratios within the portion (area) of the standard geography level that intersects an input feature will be calculated. All ratios—All available ratios will be calculated. This option is not available when using online data.	String

id_field	The field that will be used to identify the in_features parameter value—for example, the IDs of drive time polygons.	Field
out_feature_class	The output feature containing the trade area.	Feature Class
overlap_type (Opcional)	Specifies how the subgeography will be selected from the boundary layer. INTERSECT—If any of the subgeography features touch or intersect the boundary layer, they will be included in the output layer. This is the default. CENTROID_WITHIN—If the centroids of any of the subgeography features are contained within the boundary layer, they will be included in the output layer. COMPLETELY_WITHIN—Only the features of the subgeography layer that are completely contained within the boundary layer will be included in the output layer.	String
ratios (Opcional)	Specifies the ratios that will be calculated. NO_RATIOS—No ratios will be calculated. This is the default. AREA_ONLY—Only the ratios within the portion (area) of the standard geography level that intersects an input feature will be calculated. ALL_RATIOS—All available ratios will be calculated. This option is not available when using online data.	String
