While GMT has served the map-making and data processing needs of scientists since 19881.1, the current global use was heralded by the first official release in EOS Trans. AGU in the fall of 1991. Since then, GMT has grown to become a standard tool for many users, particularly in the Earth and Ocean Sciences. Development has at times been rapid, and numerous releases have seen the light of day since the early versions. For a history of the changes from release to release, see the online Release Announcements and the file CHANGES in the main GMT directory.
The success of GMT is to a large degree due to the input of the user community. In fact, most of the capabilities and options in GMT programs originated as user requests. We would like to hear from you should you have any suggestions for future enhancements and modification. Please send your comments to the GMT help list.
