map_image or map_patch? [message #8750]

Dear IDL users,

I have recently started to use map_patch for warping data to various map
projections and have been pretty happy with the results.
Some recenr testing I have done shows that map_patch is about 5 times
slower in IDL 5 compared to IDL 4. This is a little troubling as
map_image only slowed down by 1.5. These are all rough figures you
understand!

I was womdering if anyone had any pointers in choosing which of
map_image or map_patch to use in a given case? If it helps, most of
my data is 1x1 degree regular grids of ints or floats.

Thanks,

Ian Sprod
