Hi Rod, re: > Oh I thought changing the batch file the way I originally did > it....would produce the effective radius on top of the IR. > I guess not. It would have if you had begun the script with an IMGREMAP of an Effective Radius image to create LOC/AREAS.3000. The BATCH file you sent along instead used IMGREMAP to remap an IR image into LOC/AREAS.3000: IMGREMAP G13/IR27APR11 LOC/AREAS.3000 TIME=19:55 LAT=30:00 86:30 SIZE=320 320 PRO=MERC RES=6 If this line had instead been: IMGREMAP G13/ERAD27APR11 LOC/AREAS.3000 TIME=19:55 LAT=30:00 86:30 SIZE=320 320 PRO=MERC RES=6 then the rest of the modifications you made to the script should have been OK. This was likely a simple oversight... re: > I dont understand why I have to make a new grayscale though. You wouldn't have to make a new grayscale if the first IMGREMAP had bee for an Effective Radius image. I will be in my office all afternoon if you would like to chat about what you are trying to do...
