Conditional evaluation with Con

[GJB]

Hello, in ArcGIS 10. used geologic boring logs and the topo to raster tool to create a BedrockElevation raster.  However, some bedrock outcrop areas were interpolated to be at an elevation ‘higher’ than the GroundDEM, so I need to adjust these areas to actual ground elevation.  What is the best way to accomplish this?  It seems easy in concept but I’m having trouble making a formula to work in Raster Calculator. Any insight would be greatly appreciated. Thank you.

Concept:  New Raster = 

IF: "BedrockElevation" > “groundDEM”

THEN: assign elevation value from "groundDEM"

OTHEWISE: keep the elevation value of "BedrockElevation"

I tried: CON("BedrockElevation" > "GroundDEM", "GroundDEM", "BedrockElevation")

Functions are case-sensitive. Could you test

Con(("BedrockElevation" > "GroundDEM"), "GroundDEM", "BedrockElevation")

Let us know if you have any further issue?

Do you have a screengrab/text result of the actual expression?

Presumably you got an error or an unexpected result.  Could you report which and what.

Thank you for the response!!  It was solved as above.

Yes!  That was it, thank you for the response!
