I have a flat ADDE image in IDV which plots in the Map Display on 0 msl. But in reality the data represents a pressure level (I.e. 800 mb). I was hoping I could use jython to define a vertical coordinate axis, and then augment my (meta)data so the image plots nicely at the corresponding height in the atmosphere… Ideas? Any pointers to which methods from the VisAD/IDV APIs I should start with….
There is no method to easily do this. Essentially, you'll have to take apart the existing domain, add in the 800 hPa value, create a new domain RealTupleType with the appropriate coordinate system and the set the new domain on the image. It's like the reverse of GridUtil.makeDomain2D, but harder. ;-)
Couldn't you figure out where 800 hPa is on the box and use the Z Slider to move it to that location?
Another possibility would be to create a RealTupleType with the value of the level and the appropriate CoordinateSystem of Pressure to Height. Take your image which is something like:
Time -> ((x,y)->value) and create a new FieldImpl that looks like: Time -> (Pressure ->((x,y)->value))That might work, but I couldn't say for sure until someone tried it. And, it would all have to be done manually - there is no method to do that either.
Anyone else have some ideas on this? Don -- Don Murray NOAA/ESRL/PSD and CIRES 303-497-3596 http://www.esrl.noaa.gov/psd/people/don.murray/
