• realized pretty quickly from testing that there is ambiguity in my previous method to estimate Smile for geo-referenced images. Only clean solution I can so far is that required input is the raw data prior to ortho.
• Issue still remains though because it requires the user to know what orientation to use. In this case of PRISMA data , it appeared to be rotated -90 degrees, at least in the way I opened the data using SISTER. I can continue thinking to see if there is a more generalizable way to have it figure out the orientation.
