I need to perform a ???simple??? raster calculation using a Digital Elevation Model and a dbf table with a coefficient value (double); DEM10m * table value. The problem is that I need to do this over a thousand times and am trying to use the iterate table function in Model Builder to run through my list of dbf tables but get multiple errors each time.
ERROR 000539: Error running expression: rcexec() Traceback (most recent call last): File "<expression>", line 1, in <module> File "<string>", line 5, in rcexec File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\sa\Functions.py", line 4298, in Times in_raster_or_constant2) File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\sa\Utils.py", line 47, in swapper result = wrapper(*args, **kwargs) File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\sa\Functions.py", line 4295, in Wrapper ["Times", in_raster_or_constant1, in_raster_or_constant2]) RuntimeError: ERROR 000732: Input Raster: Dataset srg12_coef does not exist or is not supported Failed to execute (Raster Calculator).
Can a table iterator be used with the raster calculator?
How can I get the calculator to recognize/accept my tables? Do they need to be in a different format? Or do I need more explicit map algebra syntax that specifically tells the calculator to extract the value in row 1, column 2 of my tables? Any help would be so appreciated! Thanks, Melissa
In that case, the tool you need to use is Get Field Value, which can pull the value from the field into a model variable which you can in turn use in the Raster Calculator expression.
