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.

Inputs

Name	Type	Description
Source	Categorical Map Type	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 compatible with “Signed 32 Bit Integer” or an error will be reported.
Name	Type	Description	Default Value
Mask	Categorical Map Type	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 Type	Data cell type.	Signed 32 Bit Integer
Null Value	Null Value Type	Null value of the distance map.	Default1) Based on the given Cell Type input
Truncate Distance	Boolean Value Type	If true, distance values that exceed the greatest value of the output map will be truncated, instead of reporting an error.	False

Output

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

Notes

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.

The resulting output map has one layer named “layer_0”. This is the default name for layers of a map when an explicit name is not specified.
