Abs function

Available with Image Server

Calculates the absolute value of the pixels in a raster.

Notes

If the input is an integer, the output raster will be an integer type. If the input is floating point, the output raster will be a floating-point type.

If the input is a multiband raster, the output will be a multiband raster. The function will perform the operation on each band in the input.

If the input is a multidimensional raster, all slices from all variables will be processed, and the output will be a multidimensional raster.

Parameters

Parameter name	Description
Raster	The input raster for which to calculate the absolute values.
Extent Type	Choose which extent should be used in the output raster: First Of—Use the extent of the first input raster to determine the processing extent. Intersection Of—Use the extent of the overlapping pixels to determine the processing extent. This is the default. Union Of—Use the extent of all the rasters to determine the processing extent. Last Of—Use the extent of the last input raster to determine the processing extent.
Cellsize Type	Choose which cell size to use in the output raster. If all the input cell sizes are the same, all the options will yield the same results. First Of—Use the first cell size of the input rasters. Min Of—Use the smallest cell size of all the input rasters. Max Of—Use the largest cell size of all the input rasters. This is the default. Mean Of—Use the mean cell size of all the input rasters. Last Of—Use the last cell size of the input rasters.
