the repository. See "License" below for a license of the tools in this directory.
Please also see the source code of the scripts for usage and license.

Any plate tectonic map needs to provide markers for the reader in order
to provide some orientation relative to present-day.
This script is a simple Python script to generate graticule lines at present-day in the
*.gpml file format (GPlates Markup Language).
The script generates a plain-text, xml-based file with line features at user-defined
spacing either regionally (user provides a bounding box) or globally (default).
The graticule lines can then be imported into GPlates and reconstructed.
In order to do this, the user has to have a set of polygons loaded which then used
for cookie-cutting and age-assignment for the graticules.
When exported, these features can be plotted
with GMT using different line styles (dashed, solid, etc.).
For an example, please see Figs 15-21 in Heine et al., 2013,
