Some distorted type of image. The lat/lon vlaues and the parameter
values are all assigned to each pixel but the image seems to be, I
don't know, not correct.
Is it possible to regrid the coarse resolution to a higher resolution
using some interpolation method in ENVI (not in IDL!) and also change
the map projection?
