Calculates the natural logarithm (base e) of each pixel in a raster.
The natural logarithm (Ln) is the most commonly used logarithmic function.
The input Raster can be an integer or floating point. The output of this tool is always floating point, regardless of the input type.
Input values that are 0 or negative will be NoData in the output raster.
Input values for which to find the natural logarithm (Ln).
Choose which extent should be used in the output raster:
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.
