Calc Distance To Feature Map

Description

This functor calculates a map representing the frontage distance (in meters) between a cell and the closest cell representing a feature.

Name	Type	Description
Source	Categorical Map	Map containing the features to which distances will be calculated. A feature is represented by a non-null value. Data cell type of this map must be “Signed 32 Bit Integer” or an error will be reported.

Name	Type	Description	Default Value
Mask	Categorical Map	A map used to mask the distance calculation on its null cell areas. Data cell type of this map must be compatible with “Signed 32 Bit Integer” or an error will be reported.	None
Cell type	Cell Type	Data cell type.	Signed 32 Bit Integer
Null Value	Int	Null value of the distance map.	-2147483648
Truncate Distance	Bool	If true, distance values that exceed the greatest value of the output map will be truncated, instead of reporting an error.	False
Ignore Unreachable Sources	Bool	If true, feature cells completely surrounded by other feature cells are ignored.	True
Ignore Cross Inside Sources	Bool	If true, feature cells surrounded by other feature cells on the horizontal and vertical axis will be ignored. To have an effect, “Ignore Unreachable Sources” must also be true.	True

Name	Type	Description
Distance	Map	The distance map. The distances are represented in meters. Map format has the same dimensions of the source map.

The calculated distance is the Euclidean distance and the unit used is the meter.

The mask does not interfere with distance calculations to cells located beyond null cells.
