On this page you can find user-contributed extensions to GMT, such as custom symbols and patterns, as well as data pointers [under construction].
Note: If you wish to contribute similar material, please prepare your material emulating the layout of any of the contributions
already present. We need 200x200 pixel PNG pics of each symbol and a README file etc., from which
we can make a new sub page. Please contact the GMT-team for more details.
