I have a GeoGrid object, derived from a nc file of a model run.using the cf1.0 conventions, the nc file describes say a lambertprojection. The math type of my data may then be


(Time -> ((XC[unit:km], YC[unit:km]) -> surface_temperature[unit:Pa]))

I am now trying to convert the x,y grid 'points' back to lat,lon,since I need to produce a bounding box of the data according to someother projection.


I cannot see how to proceed.  is VisADMath.java helpful at all?

I could always open the nc file manually, figure out the projectionand Y, X variable values and convert all values to reference lat,lon,but I was hoping that this be done already in the IDV classes.


Any help appreciated

Stuart
