Why does zonal statistics as table tool fail?
The Zonal Statistics as Table tool from the Spatial Analyst toolbar creates statistical summaries for a raster within the zones of a value raster and reports the results to a table. Running the tool may fail with a generic error: “Error 999999: Error executing function.”
How is the output of zonal statistics determined?
The Value layer contains the input for which a statistic is to be calculated per zone. In this example, the maximum of the value input is to be identified for each zone. The output data type is determined by both the selected statistic type and the value input type.
How to use zonal statistics as table in GeoNet?
Search on GeoNet Submit to ArcGIS Ideas. The Zonal Statistics as Table tool from the Spatial Analyst toolbar creates statistical summaries for a raster within the zones of a value raster and reports the results to a table.
How is a zonal statistic calculated in ArcGIS?
With the Zonal Statistics tool, a statistic is calculated for each zone defined by a zone dataset, based on values from another dataset (a value raster). A single output value is computed for every zone in the input zone dataset.
How is STD calculated in zonal statistics table?
RANGE — Calculates the difference between the largest and smallest value of all cells in the value raster that belong to the same zone as the output cell. STD — Calculates the standard deviation of all cells in the value raster that belong to the same zone as the output cell.
Why are the zonal Statistics in ArcGIS different?
If the resolutions are different, an internal resampling is applied to make them match before the zonal operation is performed. Should there be any NoData cells in the inputs, the resampling may cause there to be larger areas of NoData in your output than you might have expected.
Can you do zonal analysis for overlapping polygons?
If the zone feature input has overlapping polygons, the zonal analysis will not be performed for each individual polygon. Since the feature input is converted to a raster, each location can only have one value. An alternative method is to process the zonal statistics iteratively for each of the polygon zones and collate the results.
Why do I get error 999999 in raster?
One thing that occasionally creates error 999999 for me is starting a feature class or raster name with a number – this most often happens when I try to start the name with the year the data represents (2016_imagery, for example). This isn’t allowed in a name, but it doesn’t have a specific error message to tell you that, so you just have to know.
How do you calculate zonal Statistics in ArcGIS?
To make a field of unique values that does not have a reserved name, use the Add Field and Calculate Field geoprocessing tools. The input value raster can be either integer or floating point. However, when it is floating-point type, the zonal calculations for majority, median, minority, and variety will not be computed.
How to troubleshoot ArcMap and ArcGIS error 999999?
Troubleshooting 101, but we all need a reminder sometimes. Turning it off and back on again can work!
What does error 999999 mean in Java?
ERROR 999999: Error executing function. Failed to execute (CalculateField)… I want the expression to run and populate the new field in the feature layer,fc. The calculate field tool is notoriously finicky. Everything has to be so exact to get it to execute properly.
What does invalid output extent mean in ArcGIS Pro?
010092: Invalid output extent. The extent specified, either in the environment or as a parameter, is invalid for the output that will be created. Specify a valid extent for the output. If you are not sure what to use, set the Output Extent in the Environment setting to Default.
