I'm trying to convert a dem that is now a grids z values from meters to feet.
I am trying to use the following instructions to do this from our company manual but I am getting stuck on step two where I need to open the themes table because it is greyed out. Is there something I am missing. Also, is there an easier way to do this in Arc 9.x if anybody here knows that I'm not married to 3.x.
Thanks, here are the instructions I'm using.
Set View's working directory to directory of existing DEM grids
Open theme table - click on value - table - start editing - minimize
In View 1 -Analysis - Map calculator - creates "map calculation 1" (calc1) which is the grid displayed in meters in the view
Note: "sp" means space, not the letters s and p
([DEMname]sp*sp3.28084) - Evaluate
From theme pull down menu, convert "map calculator 1" (calc1) to grid
Rename using a descriptive name and appropriate projection suffix (e.g., "-83s")
