thanks<br>
actually you can plot UTM data but geography is not correct ... I'm<br>
looking for a pdef or bilin option in order to remap data (as you can do<br>
with other projections)<br>

Way back (v1.8?), B.-J. Tsuang had contributed a UTM patch for GrADS but this never made into the main codebase.</div>

> I use UTM coordinates with GrADS all the time, so it will work. However, in most cases you need to modify your coordinates. I multiply each coordinate by 10E-5 or 10E-6 since GrADS wants Lat/Lon coordinates. That makes pseudo Lat/Lon coordinates that will plot just fine.<br>
