As part of my research, I'm starting to learn ISIS and display MARCI imagery. I've quickly learned that MARCI imagery is pretty hard to work with since it's a push-frame camera, which a few people claim is the reason there's a relative lack of papers published using its data. I tried to run through the process for an entire pole-to-pole MARCI swath and after processing cam2map for nearly 48hrs, the Linux box booted me off. That's on 8GB of RAM, BTW. After that, I started cropping the images to much smaller chunks. Below is my first recognizably Martian image that I've been able to produce (I've only been at this for a few days). This is from the southern mid-latitude highlands. Some things I don't understand...why is the left part of the frame somewhat washed out/bright? The red/yellow bands around the edge are areas where there apparently is no data in the green or blue channels...not sure why. My processing steps are:

marci2isis
spiceinit
marcical
crop
cam2map
automos

I need to figure out how to really speed this up. I want to look at complete MARCI global mosaics over at least 1 martian year if not the entire MRO mission. At this rate, that would take years laugh.gif . Apparently an ISIS update is coming out in the near future which will help work with LROC WAC images. LROC WAC is also pushframe, so maybe that will help with MARCI imagery as well?

Thanks in advance!

Continuing to work with MARCI data, now rendering videos at real-time orbital speed. This orbit captures some dust storms along the southern edge of Claritas Fossae, nice albedo markings in Syria Planum, a handful of the Tharsis Montes, and the northern polar cap lit by the midnight sun.
