Label | Explanation | Data Type |
Input raster or feature source data | The input source locations. This is a raster or feature identifying the cells or locations that will be used to calculate the Euclidean distance for each output cell location. For rasters, the input type can be integer or floating point. | Raster Layer; Feature Layer |
Maximum distance (Optional) | The threshold that the accumulative distance values cannot exceed. If an accumulative Euclidean distance value exceeds this value, the output value for the cell location will be NoData. The default distance is to the edge of the output raster. | Double |
Output cell size (Optional) | The cell size of the output raster that will be created. This parameter can be defined by a numeric value or obtained from an existing raster dataset. If the cell size hasn't been explicitly specified as the parameter value, the environment cell size value will be used if specified; otherwise, additional rules will be used to calculate it from the other inputs. See the usage section for more detail. | Analysis Cell Size |
Output distance raster (Optional) | The output Euclidean distance raster. The distance raster identifies, for each cell, the Euclidean distance to the closest source cell, set of source cells, or source location. The output raster is of floating-point type. | Raster Dataset |
Distance Method (Optional) | Specifies whether the distance will be calculated using a planar (flat earth) or a geodesic (ellipsoid) method.
| String |
Input raster or feature barrier data (Optional) | The dataset that defines the barriers. The barriers can be defined by an integer or a floating-point raster, or by a point, line, or polygon feature. | Raster Layer; Feature Layer |
Out back direction raster (Optional) | The output Euclidean back direction raster. The back direction raster contains the calculated direction in degrees. The direction identifies the next cell along the shortest path back to the closest source while avoiding barriers. The range of values is from 0 degrees to 360 degrees, with 0 reserved for the source cells. Due east (right) is 90, and the values increase clockwise (180 is south, 270 is west, and 360 is north). The output raster is of type float. | Raster Dataset |
Return Value
Label | Explanation | Data Type | Output direction raster | The output Euclidean direction raster. The direction raster contains the calculated direction, in degrees, that each cell center is from the closest source cell center. The range of values is from 0 degrees to 360 degrees, with 0 reserved for the source cells. Due east (right) is 90, and the values increase clockwise (180 is south, 270 is west, and 360 is north). The output raster is of integer type. | Raster |
