About GMT6
GMT6 is an open-source collection of command-line tools for working with geographic and Cartesian datasets. It can filter data, fit trends, create grids, and transform coordinates between map projections. The software also produces scientific illustrations, including simple x-y plots, contour maps, shaded surfaces, and three-dimensional perspective views. This combination supports both data preparation and visual presentation in a command-line workflow. GMT includes numerous map projections and transformations, along with supporting geographic data such as coastlines, rivers, and political boundaries. Country polygons can also be used optionally. The toolset is used to process data, create publication-quality figures, automate workflows, and make animations. Its breadth makes it relevant to geospatial analysis and scientific plotting, though the supplied information does not detail specific input formats, commands, or animation capabilities.
