In the Export Raster Data dialog box, click the Format drop-down arrow and select TIFF.Ĥ. Right-click the raster dataset in the Table Of Contents > Data > Export Data, to change the file format of the input raster dataset.Ģ. Once the fields are saved as attributes of the new file, the Field Calculator tool is enabled.įor this example, the raster dataset is exported to TIFF.ġ. The output raster dataset is a new GRID file, and the fields are saved as attributes in the new file. In this example, the input raster dataset is in the GRID format.
Use the Add Field tool to add the desired field(s) to the target table, perform the field calculation, and delete the appended fields.Use the Calculate Field geoprocessing tool on the raster attribute table.Export the raster after joining the field to a new format (such as TIFF), and calculate the fields on the new raster.Export the data to make the join permanent.Add the joined tables or layers to ArcMap, and perform calculations on the data separately.There are a few options for performing calculations on joined data and resolving Field Calculator issues. Generally, the Field Calculator does not calculate fields in a raster attribute table if the join is not permanent. There are several reasons why the Field Calculator tool may be disabled on a field, and these are detailed in ArcGIS Help, Fundamentals of field calculations. In the Results window, the error is 000728: "There was a failure during processing, check the Geoprocessing Results window for details." With Esri GRIDs, Field Calculator calculations fail with an error when attempting to populate a field with the values of a joined field. When disabled, it is not possible to calculate the field value in a raster dataset's attribute table.
In ArcMap, when a table is joined to a raster attribute table, the Field Calculator may not display the fields from the joined raster, or the calculator may be completely disabled. Problem: The Field Calculator does not display or calculate joined fields in a raster attribute table Description
