Information on UNAVCO's response to COVID-19

This short course will be offered in a virtual format only.

This course will cover the use of GMT 6 in geodesy using UNIX shell scripting. Lectures and exercises will be given to teach the basic conventions of using GMT, such as plotting grids, images, and vector data (points, lines, polygons). Labs will include both processing and mapping of various data sets relevant to geodesy.

This course does not have a registration fee.

Participants will apply to participate as we expect demand to exceed capacity. Decisions will be made on responses to prompts in the application. Priority will be given to applicants from UNAVCO member institutions and who need the training to conduct research in the next year. (Check to see if your institution is a member of the UNAVCO consortium.)
