Planetary Data Workshop

2 Weeks ago I had the pleasure of going to Flagstaff AZ for the Planetary Data Workshop. It was a conference for scientists to express their needs and for engineer types to discuss their solutions. As can be guessed from the name, our topics were the dispersal, the processing, and the tools used for scientific imagery of the planets in our solar system (primarily from NASA’s robotic missions).

I was at the conference to discuss my software product, Ames Stereo Pipeline. I gave two talks and eventually they’ll be available on YouTube. I also gave an hour long tutorial that is now online. It’s the video above. I’m not sure how interesting it is to watch but it was a lot of fun performing the tutorial. I now realize how much of a nerd I sound like. I ended up throwing away my prepared HiRISE and LRO-NAC imagery. The crowd that attended seemed more interested in the mass processing of CTX imagery. I, unfortunately, did not have any CTX data on my laptop. Instead, I asked Fred Calef from JPL for a CTX stereo pair that he wanted processed. To my benefit, ASP v2 processed it autonomously without hassle during the demo! My laptop managed to chunk through the data in 15 minutes. I spent most of the tutorial just talking about the ancillary files and what users can look into to see if their output will turn out all right.

Shooting from the hip for a tutorial could have bitten me pretty badly. But I think ASP really has improved a lot and is ready for mass production environments. I’m trying to push for one for earth polar imagery but there are many more datasets that could have this same treatment. I think that idea became clear to the 30 guests who attended my tutorial. We’ve had an uptick in downloads and I hope that means I’ll be seeing some cool 3D models in the future.

Sidenote:  I found out that Jay Laura from Penn State has a blog going called Spatially Unadjusted. He’s a GIS guy who also uses ASP (Aww yeah). He presented a poster on his experience of using ASP v1.0.5 for LRO-NAC imagery.

ASP v2 Status Update

If you watch your email or ISIS’s website like a hawk, you’ll notice ISIS 3.4.0 just dropped this week. So where’s Ames Stereo Pipeline in all of this?

The current plan is to get Ames Stereo Pipeline 2.0 out before the Planetary Data Workshop on June 25th in Flagstaff. At this meeting I hope to be giving a tutorial and showing off all the cool stuff the community and the team have been developing for ASP.

I currently have two limiting factors that I hope will get resolved in the next 2 weeks:

  • ASP and Binary Builder need to agree with the changes in ISIS 3.4.0.
  • The NASA Ames Lawyers need to re-license Vision Workbench under the Apache 2 license. ASP has already been re-licensed to Apache 2, however one of its prime dependencies is Vision Workbench. This is a legal block against releasing binaries.

Thank you all for your patience and for doing neat projects with Ames Stereo Pipeline. I enjoy seeing the pretty pictures at science conferences.

Things to look forward in this next release are:

  • Digital Globe Image support.
  • Faster and Memory efficient integer correlator.
  • GDAL projection interface for point2dem.
  • Parameter settings from command line and configuration file.
