Raster Calculator Error

AndrewMontreuil — Fri, 02 May 2014 14:18:16 GMT

I am getting an error running raster calculator that I can't figure out.

I have 2 rasters, narr_grid_Clip and sc_neg15. The first (narr...) has values ranging from 1 to 10. The second (sc...) only has data when the first is equal to 1. The calculation I am trying to run is very long, but repetitive with other layers similar to sc_neg15 that correspond to other values of narr_grid_Clip . I have trimmed it down to just the part dealing with sc_neg15, but the error remains exactly the same. I figure it will be easier to debug the small version, and then apply it to the larger one as a whole.

Here is the simplified calculation:
[INDENT]Con("narr_grid_Clip" == 1,"sc_neg15")[/INDENT]

And the error messages:
[INDENT]xecuting: RasterCalculator Con("narr_grid_Clip" == 1,"sc_neg15") H:\ajm236.gdb\rastercalc3

Any help would be greatly appreciated.

Same problem for me.

Exporting a tool that works well in Model builder to Python and running it as a script produces this error.

Band_1 = "D:\\tmp\\raster.png\\Band_1"
Band_2 = "D:\\tmp\\raster.png\\Band_2"
Band_3 = "D:\\tmp\\raster.png\\Band_3"

# Process: Raster Calculator (Raster Calculator) (ia)
ap_tmpCon = "D:\\tmp\\lcFromRaster.gdb\\ap_tmpCon"
Raster_Calculator = ap_tmpCon
ap_tmpCon = Con((Band_1 == 176) & (Band_2 == 176) & (Band_3 == 176), 1, 0)
ap_tmpCon .save(Raster_Calculator)

gets me the same error. I assume its a but with the Con function in arcpy.ia .

Any ideas how to fix?
