This is the web version of the Terra Antiqua manual. It will guide you through the successive steps leading to the making of a global paleogeographic reconstruction. The various tools of Terra Antiqua may also be used for more specific tasks (see Introduction).
The manual is organised according to an intuitive workflow we designed to make a global reconstruction. Throughout the process, you are provided with guiding tips for each algorithm and tool.

This homepage contains the index of the manual and general information about downloading and installing the plugin.

The Post section at the bottom shows the latest events regarding Terra Antiqua.

In the page for each tool, we describe their use, and technical characteristics in detail. A step-by-step description will then guide you through the practical use of each tool.

These step-by-step instructions include:

  • WARNINGS recommendation: critical information for the correct use of the tool avoiding errors.
  • NOTES: important indications related to functionality.
  • GUIDING TIPS recommendation: recommendations about when and how to use the tool, or additional information about the algorithm.

Besides, embeded in the description of each tool, you will find a section on:

  • Technical details: parts of the descriptions that deal with the functioning of the algorithms.

At the end of each page, you will find a link to the GitHub discussions where you can comment on the tools, suggest any modification, share ideas, etc… Your feedback is most welcome!!
