I'd like to second Larry's comments. He has hit on the major
impediments we have in migreating away from Gempak to IDV.

1) Quality of graphics. We have a number of professors, scientist,
and students that submit graphics from GEMPAK for publication.
We don't feel that the quality of IDV is there yet and probably
won't be unless it has the capability to output some form of
vector graphics. A couple of our professors consider this the
2) Text products. When I look at the weather, I spend as much time
looking at the NWS text products as I do looking at graphic displays.
3) My web site is built largely on GEMPAK. I get about 120,000 actual data
requests (not hits) per day. An IDV based server would be too
slow to be feasible at this time. While 3D is nice, IDV is still uses
too much memory to be unable to load large 3D sets such as a loop of
level II radar or high resolution grids.
4) Ease of scripting. Have you ever tried to manually edit an xidv file?
5) GEMPAK's forte has and continues to be in manipulating grid fields. IDV
is improving in this area but still isn't up to GEMPAK.
As a note, we played with using IDV for our teaching and have gone back to
mostly using GEMPAK.
