Calc Distance To Feature Map

Description

Calculates a map representing the Euclidean distance, in meters, from every cell to the nearest cell representing a feature.

Inputs

Name	Type	Description
Source	Categorical Map Type	Map for which distances are calculated. A feature is represented by any non-null value.

Optional Inputs

Name	Type	Description	Default Value
Mask	Map Type	Map restricting which cells have their distance calculated: only cells whose corresponding cell in Mask is non-null have a distance calculated.	None
Cell Type	Cell Type Type	Cell type of the distance map.	Signed 32 Bit Integer
Null Value	Null Value Type	Null value of the distance map.	-2147483648
Truncate Distance	Boolean Value Type	If true, a distance exceeding the largest value representable in the output map is truncated to that largest value instead of reporting an error. This is an advanced port.	No

Outputs

Name	Type	Description
Distance	Map Type	Map of distances, in meters, with the same dimensions as Source.

Notes

Mask only restricts which cells receive a calculated distance in the output; it has no effect on which cells of Source are collected as features, so a feature located outside the area defined by Mask still influences the result.

Raises an error if Null Value is not compatible with Cell Type.

Reports a warning if Cell Type could degrade performance.
