Alan, Your version of GEMPAK is limited in the channel numbers that will be expected in the GINI image, and the channel 16 I used is outside of the allowed range. I had thought I made it low enough, but didn't. I always increase my allowed channel numbers here since the sounder products on NOAAPort use that higher range of numbers. I've modified the channel number from 16 down to 5 in the attached ustopo_dem5.gini2, and the imgtyp.tbl entry is: TOPO TOPO_DEM5 0 95 33 16 1 upc_dem5.tbl Try this and see if it works for you. I'm working on seeing if I can use AREA instead of GINI that would avoid some of these hassles- just don't want to create problems reusing old GOES7 numbers in case someone is using GOES7 data for something out there.
