The above slides are a tutorial for people who want to learn how to do watershed delineation using Shuttle Radar Topographic Mission (SRTM). The tutorial is free and licensed as CC BY SA. This is a direct link to the slides in Google Docs where they can be downloaded in multiple formats.

The tutorial uses SRTM 1 Arc-Second (30 meter resolution) data to map the Faro River basin near the Cameroon and Nigeria border. The methods can be applied to any region as the data for the tutorial is free (open data) from USGS that can be downloaded here http://earthexplorer.usgs.gov/.

I created this tutorial for my Advanced Geographic Information Science students at UBC in March 2016. The tutorial uses ArcMap 10.3, so you will need access to that software and the software’s Spatial Analyst license.

Let me know if you find it useful or see something that could be improved!

Where are Tchabal Mbabo and the Faro River?
