Hi, I'm trying to georeference an image covering a very large area -
pixels in the ocean were given as NaN. This image was projected, but I
was not able to set up its projection in Envi based on the available
parameters. However, there are lat/lon files for all of the grid
points in the image. So I thought I could use GLT to register the
image myself. Then there are NaNs in the lat/lon files same as in the
image file. Does anybody have expereince of applying GLT from lat/lon
with missing values? Is this possible?

Thanks for any advice,

Jenny
