Hi folks,
Thanks to Mike Schienle, I worked out how to display an image (with lat/lon
coordinates defined for each pixel) on a map base, using
triangulate
trigrid
map_image
However triangulate seems to be taking up a lot of memory and consequently
crashing IDL when I use medium/large remote sensing images (> 200000
pixels). My SGI has 96 MB of physical RAM.
Has anyone come up with a more space/time efficient way of resampling
images to a regular lat/lon grid? I didn't see another IDL built-in
routine or userlib routine that would handle this problem.
