Calculates, for each cell, the Euclidean distance to the closest source.
The input source data must be a raster layer.
The NoData values that exist in the Source Raster are not included as valid values in the function. The value 0 is considered a legitimate value in the source raster. A Source Raster can be created using the extraction tools or the Clip function.
If you have source features, you can first convert them to a raster dataset using the Rasterize Features function. Use a consistent input for the Raster input to that function. This will ensure that the features are properly converted to a raster dataset using the same cell size, extent, and spatial reference.
The Maximum Distance is specified in the same map unit as the Source Raster.
If the Mask has been set in the geoprocessing environments, and the cells to be masked will cover a source location, the Euclidean calculations will occur on the remaining source locations. The source cells that are masked will not be considered in the computations; these cells will be assigned a value of NoData. Any cell location that is assigned NoData on the input surface will receive NoData on all the output rasters. See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this function.
The input raster that identifies the cells or locations to which the Euclidean distance for every output cell location is calculated.
The input type can be an integer or a floating-point type.
The threshold that the accumulative distance values cannot exceed. If an accumulative Euclidean distance exceeds this value, the output value for the cell location will be NoData.
The default distance is to the extent of the output raster.
The cell size at which the output raster will be created.
If the cell size was explicitly set in Environments, that will be the default cell size. If it was not set, the output cell size will be the same as the Source Raster.
Determines whether to calculate the distance using a planar (flat earth) or a geodesic (ellipsoid) method.
Geoprocessing environment settings for global functions are controlled at the application level. Setting processing environments in ArcGIS Pro can be done by clicking the Environments button on the Analysis tab. See Analysis environments and Spatial Analyst for additional details on environment settings.
The following environments are supported by this global function:
