+* **When:** June 26-29 (Monday-Thursday), 2023, online
+* **Where:** Via zoom only
+* **Repository:** https://github.com/GenericMappingTools/gmt-for-geodesy

+This course will cover the use of Generic Mapping Tools (GMT) in geodesy using
+UNIX shell scripting. Lectures (on YouTube) and exercises will be given to teach the basic
+conventions of using GMT, such as plotting grids, images, and vector data (points,
+lines, polygons), and making animations. Labs will include both processing and
+mapping of various data sets relevant to geodesy.
