Hey all,I may have asked a similar question in the past, but didn't find it in the archives. So here goes:
We do some biophysical modeling, primarily to support agriculture. Some of our models are thermal, others combine weather data with remote-sensing imagery. We have a whole silo of legacy apps in Perl, C, and FORTRAN (!); among our products is a series of maps like this one showing evapotranspiration for the region:

The grid cells are MUCH bigger than you'd guess by looking at the map; each grid takes up 0.4 degrees of both latitude and longitude, so the data behind the map image is only 31x21 cells. There's a package called GrADS which we use to produce the nice isoclinal maps from our data. All this stuff runs at night, precooking all the data and generating all the maps.
I'd really like to jettison all the creaky old stuff, keep the gridded data in relational tables, and just use GeoServer to generate maps on the fly. I could easily do a choropleth of the data, of course, just build the grid geometry as polygons once and then link to the data tables. But that would be all blocky and look horrible. Do any of you know a way to make GeoServer do the isoclines?
Thanks ever so, rw
