Zonal Statistics
Zonal Statistic and Zonal Statistic as Table
Zonal statistics calculates or performs the statistics with the values of the value raster. Then get the statistics values for each zone based on the zone raster. A zone is defined as all the cells that have the same value in the input (the discontinuous cells of same value are accepted to be a zone).
Zonal Statistic as Table shows the result in Table instead of raster.
Zone raster defines the shape, value and position of the zone, and the input value raster provides the original data for calculation. Ten statistics types are available, Majority, Minority, Maximum, Mean, Minimum, Median, Range, Standard deviation, Sum and Variety.
Zonal statistics analyzes the situation in zones. For instance, users can analyze the lowest elevation of each sink using the zone statistics analysis, and then employ Zone Fill to get the lowest elevation of outlet and get the depth of sink. This is quite helpful for filling the wrong sinks and reducing the elevation of basin boundary.
