Summary
Creates a raster object in which each pixel contains the value in an argument list that is at a certain level of popularity.
Discussion
For more information about how this function works, see the Popularity tool.
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntax
Popularity (popularity_raster, rasters, {extent_type}, {cellsize_type}, {process_as_multiband})
Parameter | Explanation | Data Type |
popularity_raster | The input raster that defines the popularity position to be returned. | Raster |
rasters [rasters,...] | The list of input rasters. | Raster |
extent_type | The method that will be used to compute the extent of the output when the input rasters have different extents.
(The default value is FirstOf) | String |
cellsize_type | The method that will be used to compute the pixel size of the output when the input rasters have different pixel sizes.
(The default value is FirstOf) | String |
process_as_multiband | Specifies how the bands of the input rasters will be processed.
(The default value is False) | Boolean |
Data Type | Explanation |
Raster |
The output raster. |
Code sample
Calculates the values in the set of input rasters that reach the specified level of popularity.
# Import system modules

#Set the local variables
popularity_raster = r"c:\temp\value_raster.tif"
rasters = [r"c:\temp\raster1.tif", r"c:\temp\raster2.tif", r"c:\temp\raster3.tif"]
#Execute
output_raster = Popularity(popularity_raster, rasters, "UnionOf", "FirstOf", True)
