Week 5: Photogrammetry

Research:
The principal goal of the week was to build a stereo DEM of an area north of Matatiele. First try gave dubious results because I didn't initialize the stereo pair with the true calibration parameters. Phoned the Chief Directorate: Surveys & Mappings in Cape Town, and the promised to send me the calibration reports, which of course, they didn't. Even after repeated email requests. Angry about that.

So the rest of the week kinda slowed down from there. Prepared for, and performed more aerial photography of Rivieres de Galets from a small aircraft. The planning paid off, and the images are beautiful and at a very acceptable resolution. Further, identified areas of gully erosion in the South African study area that will be studied using time-series analysis. Also had a very positive meeting with my supervisor, and we decided on a list of candidates for my PhD jury. Exciting stuff.

Again, zip. Not good.
