How does the cell statistics tool in ArcPy work?
The Cell Statistics tool creates a multiband output when processed as MULTI_BAND. In ArcPy, if all inputs are multidimensional rasters with the same number of variables, the tool will perform the operation for all slices with the same dimension value, and the output will be a multidimensional raster.
How are cell statistics calculated in ArcGIS Pro?
Calculates a per-cell statistic from multiple rasters. The available statistics are Majority, Maximum, Mean, Median, Minimum, Minority, Range, Standard deviation, Sum, and Variety. The order of the input rasters is irrelevant for this tool.
How does the cell statistics tool work in Python?
The Cell Statistics tool creates a single-band output when processed as SINGLE_BAND. If the Process as multiband parameter is checked ( process_as_multiband is set to MULTI_BAND in Python), each multiband raster input will be processed as a multiband raster, and the output will be a multiband raster.
What to do if you get an error in ArcPy?
If the above code was used and a geoprocessing tool error occurred, such an invalid input, this would raise arcpy.ExecuteError, and the first except statement would be used. This statement would print the error messages using the GetMessages function.
What is the value of a nodata cell in ArcGIS?
For the RASTERVALU field of the attribute table, NoData cells in the value raster will be given a value of -9999. The interpolation option determines how the values will be obtained from the raster.
When to use a multidimensional raster in ArcPy?
In ArcPy, if one or more of the inputs is a multidimensional raster and the other input is a constant, the tool will perform the operation for all slices for all variables using the constant value, and the output will be a multidimensional raster.
What are the available statistics in ArcMap-ArcGIS?
The available statistics are Majority, Maximum, Mean, Median, Minimum, Minority, Range, Standard deviation, Sum, and Variety. The order of the input rasters is irrelevant for this tool. When a multiband raster is specified as one of the Input rasters or constant values ( in_rasters_or_constants in Python), all the bands will be used.
What are the output cell values in ArcGIS Pro?
For the Maximum, Minimum, Mean, Median, Majority, Minority and Sum statistic types, if a single raster is used as the input, the output cell values will be the same as the input cell values. For Range and Standard deviation, the output cell values will all be 0. For Variety, it will be 1.
