Con function on Zonal Geometry Raster

PeterPostma — Sat, 28 Sep 2013 17:40:19 GMT

I have a Zonal Geometry output raster that I would like to perform the Con tool/function on. When I try I get this error:

Executing (Con): Con "C:\Users\Agent\Desktop\FOR2286\Spatial Analysis and Modeling\Reclassify\Data\Woodlot II\UNB Woodlot.mdb\ZonalGe_Regi1" 1 "C:\Users\Agent\Desktop\FOR2286\Spatial Analysis and Modeling\Reclassify\Data\Woodlot II\UNB Woodlot.mdb\SQHabitat" # ""Value" >=50000"

I am working in ArcMap 10.1, windows 7 64 bit pro. The Zonal Geometry raster is 32 bit floating. It seems like any Con function/tool cannot read the values in the zonal raster.

The workflow is originally from a simple model I made: Raster calculator output raster into Region Group, Region Group raster into Zonal Geometry, Zonal Geometry raster output into Con tool or raster calculator for areas >=50000 meters square and I get this error.

I have had the zonal raster in personal and file geodatabases, on its own in a folder, I've converted the raster to 16/8 bit, taken out spaces in paths and had the same error.

In the above error I've typed the expression as the sql builder does not let me choose/see a "value" field.

Any suggestions?

PCP

Some suggestions:

1. Make sure the zone raster is interger-based and has a raster attribute table built for it
2. Use FGDB or GRID format rasters (don't use a personal geodatabase, unless there is a good reason)
