This functionality is currently only supported in Map Viewer Classic (formerly known as Map Viewer ). Note: To run this tool, the portal must be configured for raster analysis. The maximum number of cores that can be utilized is limited to 4. The Zonal Statistics as Table tool summarizes the values of a raster within the zones of another dataset and reports the results as a table. By default, this tool will take advantage of multi-core processors. ![]() The number of rows in the output table is the number of zones. As I've not experienced any error message while using the following. How does zonal statistics work for a statistic See how Zonal Statistics works for the specific behavior of any statistic. ![]() Graph Coloring is explained by William Huber: Exploding Overlapping Polygons into Non Overlapping Polygons. I suggest you look at repairing the geometry of your polygons or reload them into a new Feature Class. When I determine watersheds for my rail or road alignments, they overlap of course. I've been using the Spatial Analyst Supplemental Tools for quiet a while now for my hydrological model for determining average catchment slopes. For the Zonal Statistics as Table, when you specify that the data is to be processed as multidimensional, it will generate a flat table output with the statistics computed for all zones and slices.
