Once you figure out how the keyword parameters work, you can use
MAP_2POINTS to generate an equally-spaced line of points along a great
circle arc. Then use INTERPOLATE to interpolate to those points. You
can use the CURSOR procedure to interactively select the end points of
the arc.

I have successfully contoured it and I am wondering if anyone has any advice on how to create profiles using the interpolate command of areas on the contour map I find specifically interesting. My data goes from 0-90s latitude and 270-360 longitude.
To specify even more I think I have written a code that will create an image profile I am just confused on how to actually specify the beginning and endpoints along the line.
