Updated geological time scale color palettes

While it has been a little break over the summer on this blog, I have nevertheless been able to make a few updates related to the geological time color palettes (see this link for the original post). I have added the GTS2004 palettes (epochs and ages) and also the SEPM95 timescale. The color palettes (or *.cpt files) are designed for use with the Generic Mapping Tools (GMT) but can also be loaded in GPlates. On cpt-city, other formats are also available:

The gradients on cpt-city are usually available in each of the following file formats:

  • Generic Mapping Tools, GMT (cpt)
  • CSS3 gradients (c3g)
  • GIMP (ggr)
  • Gnuplot palette files (gpf)
  • POV-Ray colour map headers (inc)
  • PaintShop Pro’s native format (having the extension PspGradient), which can also be read by Photoshop (psp)
  • The SAO format DS9 (sao)
  • Scalar vector graphics gradients (svg)

Both palettes are still incomplete and require the extension back in geological time or adding eons or epochs. You can find the files on my BitBucket repository (https://bitbucket.org/chhei/gmt-cpts/). Any contribution to extend the individual files or add new timescales (or formats such as for QGIS) will be greatly appreciated!
