Teaching

I teach the following courses in the UW Department of Civil and Environmental Engineering:

  • Advanced Surveying (GNSS, SfM, UAVs, TLS)
  • Geospatial Data Analysis (with Python)

Students can check the UW time schedule for updates.

Code

I’m a big proponent of free and open-source software.

Much of my code (including this website) is publicly available on github.

I use the following on a daily basis:

  • Python
  • NumPy/SciPy/Matplotlib
  • GDAL/OGR
  • bash
  • QGIS
  • Ames Stereo Pipeline
