How is the mean calculated in zonal statistics?
Statistic type to be calculated. MEAN — Calculates the average of all cells in the value raster that belong to the same zone as the output cell. MAJORITY — Determines the value that occurs most often of all cells in the value raster that belong to the same zone as the output cell.
Which is the largest value in zonal statistics?
MAJORITY — Determines the value that occurs most often of all cells in the value raster that belong to the same zone as the output cell. MAXIMUM — Determines the largest value of all cells in the value raster that belong to the same zone as the output cell.
How is the data type dependent on zonal statistics?
The data type of the output is dependent on the zonal calculation being performed and the input value raster type. See how Zonal Statistics works for more information. By default, this tool will take advantage of multi-core processors. The maximum number of cores that can be utilized is limited to 4.
What does the nodata mean in zonal statistics?
NODATA — Within any particular zone, if any NoData cells exist in the Value raster, it is deemed that there is insufficient information to perform statistical calculations for all the cells in that zone; therefore, the entire zone will receive the NoData value on the output raster. The output zonal statistics raster.
How does zonal statistics work in Spatial Analyst?
For majority and minority calculations, when there is a tie, the output for the zone is based on the lowest of the tied values. The data type of the output is dependent on the zonal calculation being performed and the input value raster type. See how Zonal Statistics works for more information.
Which is an example of zonal Statistics in ArcGIS?
The output zonal statistics raster. This example determines for each zone the range of cell values in the Value input raster. This example determines for each zone the range of cell values in the Value input raster. # Name: ZonalStatistics_Ex_02.py # Description: Calculates statistics on values of a raster # within the zones of another dataset.
