[IDD #NCA-821765]: LATLON with McIDAS

Hi Jim,

I always love to hear when problems are solved!

Ah Ha!

re:

Hmm... this was NOT a very helpful error message, was it?!

Very good.

I wouldn't have expected this big of a difference when doing an IMGREMAP first!

I am not sure what you mean by "remap the images as a single dataset".  If you
mean that it might be more efficient to create each remapped image as the 
original
is received, and then created a separate ADDE dataset that is composed of
the remapped images, then I would think that this would be preferable to
trying to remap each image each time a display script is called by your
web interface.

Am I understanding your question correctly?  If not, please
explain further.

re:
> Thanks again.

No worries.

Cheers,

Tom
