How to retain Value Attribute Tables while performing grid analysis?

RickFisher — Tue, 20 Sep 2011 17:53:53 GMT

Is it possible to retain the VAT on a integer grid while performing a conditional expression? Unfortunately, the output is a floating point grid with the loss of the VAT. Anyone in the forum know of a way to perform conditional analysis on a integer grid and retain the VAT?

Thanks,

Rick

Floating point grids can not have VATs. Make sure your output is an integer grid and use the "build raster attribute table" or "BuildVAT" tool. If you need floating point values, multiply by 10^n (where n is the number of decimal places you wish to retain) before truncating/rounding to an integer raster.

The final step once you have performed the con statement and processed it back to an integer as described, would be to export the vat from the original raster and then join it back.
