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:

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.
