PaleoMapR 0.1.0 (alpha)

First public release, for testing and feedback. Buttons, defaults and file names may still change.

  • The paleogeographic map editor (standalone version of 2026-10-26) as an R package: run_app() starts it, pm_setup() prepares a working folder (Python with pyGPlates, the open data sets, HadCM3L climate files and the corrected grids of the chosen ages), pm_load() gives its functions for scripts.
  • Windows launcher (PaleoMapR-launcher.zip on the release page): SETUP.bat installs everything, prepares the data in the launcher folder and puts a desktop icon.
  • Map editor: every PaleoDEM age 0–540 Ma, four plate models, PBDB and Macrostrat records, your own points (marine, deeper shelf, evaporite, terrestrial, reef, glacial), excluded records, undo, rebuilding of the fossil-corrected grid with statistics.
  • Figure tab: many projections, whole map / zoomed-in / composite, localities, symbols, scale bar and north arrow, HadCM3L climate layers (as run, or with a local correction to your map), wind and current arrows, rivers, sea ice.
  • Faster map switching and Figure redraws (cached editor maps and relief shading).
  • About tab with the version, the works to cite, a daily update check with “Update and restart”, and a button that closes the editor.
  • The table of database records is rebuilt when its classification rules change (checksum), not after every update of the package.
