RT 24 - Part 4: Parsing binary SBET files with python's struct

2011-11-23T21:08:00.000-08:00

Topics include "What is GIS," using glob.glob to expand file names with "*", using sys.argv directly to list input files and using argparse to properly handle command line arguments.

RT 23 - Part 3: Parsing binary SBET files with python's struct

2011-11-19T05:27:00.000-08:00

In this class, we do our first mercurial pull of changes. We then add helper functions to our sbet.py module to give us the number of datagrams in an sbet file, tell us at what offset any particular datagram is located and add a generator function allowing cleaner for loops over sbet files.

Remember that at this point, you should be getting the org mode formatted class notes via mercurial (hg). To get set up:

mkdir ~/projects
cd ~/projects
sudo apt-get install mercurial # Install hg on ubuntu & debian linux
hg clone https://bitbucket.org/schwehr/researchtools

And every time you start working on the class, do a pull and update to get the latest versions.

cd ~/projects/researchtools
hg pull   # Bring the changes down to the local "repo"
hg update # Change the working files to have the latest changes

Rob Braswell has tentatively agreed to give us a lecture on Data Analysis with R on Nov. 29th. Rob taught EOS 864 while he was a full-time Research Professor at UNH. I haven't done any work with R myself, but I've seen some really great work done with it. I'm super excited to sit in on his class.

Notes for the class should now be retrieved via mercurial/hg from https://bitbucket.org/schwehr/researchtools. The rest of the material is in the usual locations in the class directory: mp3, pdf, html
