Error in georeferencing using map_patch? [message #37422]

I'm working with a 30x90 array that is basically representative of a
50km satellite footprint. In displaying the image, I noticed that
they seem to be slightly off (coastlines apparent in the image, for
example, don't line up with coastlines mapped by IDL). I'm trying to
figure out a simple answer, though. I'm sure my code is correct, so
I'm not to worried about that. I'm just curious, since I'm applying a
small array to a large area (the image corresponds to, basically, a
very large meridional portion of north america), how the map_patch
program handles the referencing of each point to a given latitude and
longitude. The given lat and lon correspond to the center of the
pixel. Is this how map_patch applies it? i'm basically trying to
figure out if it is an error in idl or in the georeferencing of the
data? Lets see what else. I'm using a lambert projection.
Georeferencing was not done by me, but came with the dataset.

Thanks for some insight.

Will
