GMT is the indispensable map plotting third-party software package of software ShakeMap, which drawing strong ground motion map. Grasping GMT and applying the software to draw local maps is the necessary condi-tion, of which the software ShakeMap can play a role in Yunnan strong ground motion monitoring and researc-hing. By researching the ploting of Yunnan Province strong ground motion stations distribution map, the article analyzed GMT's components and data structure, discussed the method of drawing terrain grid data and point vec-tor data with GMT.
