2022 Short Course: The Generic Mapping Tools (GMT) for Geodesy

Dates: July 5-8, 2022, with pre-course homework sessions in June
Times: Varies per day, see detailed agenda below
Venue: Virtual

Course Description

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 symbols, vectors (points, lines, polygons), and grids (elevation, shading, radar image). Labs will include both processing and mapping of various data sets relevant to geodesy.

Learning Goals

In this course you will learn:

  • Introduction to UNIX basics and shell scripting
  • Learning the basic conventions of GMT
  • How to plot symbols, vectors, and grids
  • How to make multiple plots, inset images, and animations
  • How to access publicly available remote data
  • Make your own publication-quality figures   

Application Process

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 who are from UNAVCO member institutions and need the training to conduct research in the next year. (Check to see if your institution is a member of the UNAVCO consortium.) 

Applications are now closed.
