# gmt_API_example Examples for using GMT's C_API ## What's GMT? The Generic Mapping Tools (GMT) are widely used across the Earth, Ocean, and Planetary sciences and beyond. A diverse community uses GMT to process data, generate publication-quality illustrations, automate workflows, and make animations. Scientific journals, posters at meetings, Wikipedia pages, and many more publications display illustrations made by GMT. And the best part: it is free, open source software licensed under the [LGPL](https://www.gnu.org/licenses/lgpl-3.0.html). For those who wants to know more, please go to [GMT_site](https://www.generic-mapping-tools.org). ## What are these examples? * **griding**: call a GMT module to griding a table data. * **plot_grid**: read a grid file and call GMT modules to plot the grid to an image file. * **plot_memory**: create a GMT grid container and call GMT modules to plot the grid to an image file. ## How to run the examples? Compile the executables and then run sequentially. ```shell mkdir build && cd build && cmake .. && make ```
