Thank you Sir Fanning, I've successfully ran my code and able to see corrupted hdf files for redownload.
On my code, my input x,y pixel location for my area of interest was based from your coyote page: http://www.idlcoyote.com/map_tips/latlon2pixel.php.
I've read it again and it says, "Note that we are not checking that the latitude and longitude is actually inside our image. We should be, since we will get incorrect results if this is the case."
How am I able to check if my input pixel location falls within my desired area (based field based lat long reading)?
Cheers,
Brent
