I am not sure of the correct home for the ucar.unidata.geoloc.* package, is it IDV, Netcdf, or some other jar?Anyway, in idv 2.2 there exists ucar.unidata.geoloc.projection.LambertConformal. I am copying/transcribing this class into a GWT (Java -> Javascript) class. I note this snippet in the projToLatLon method:
double yd = (rhop - fromY);
double theta = Math.atan2(fromX, yd);
double r = Math.sqrt(fromX * fromX + yd * yd);
if (n < 0.0) {
In the call to Math.atan2, we clearly have some x distance as first parameter,
with y second.
Yet the api for java.lang.Math.atan2 suggests that the parameter order is y, x. Can anyone explain why the apparent mismatch?
I have used this class in apps before and it seems to work fine.
Thanks Stuart Maclean
