Mars

The "Percival Lowell" surface textures were updated to v3 on 22-Jun-2003.
They incorporate the following improvements:
Mars in the 19th Century

4: Mars as drawn by Giovanni Schiaparelli [Mars as drawn by Giovanni Schiaparelli] [Map of Mars as drawn by Giovanni Schiaparelli] Map of Mars as drawn by Giovanni Schiaparelli. This surface texture image was created by scaling and rotating a picture of a map of Mars drawn by Giovanni Schiaparelli in 1886. The original JPEG is available on the Web at http://history.nasa.gov/SP-4212/p6.html NASA images are public domain and they claim to have taken it from the article "Flammarion, La Planhte Mars" which originally was published in 1888.
5: Mars as drawn by Percival Lowell [Mars as drawn by Percival Lowell] [plmars-texture-v3.jpg]
plmars-texture-v3.jpg
This texture was created by joining GIFs of Percival Lowell's sketches of the canals of Mars. The GIFs are available on the Web in the appendix of the electronic edition of the book MARS by Percival Lowell, 1895.
6: Mars as imagined by Percival Lowell [Mars as imagined by Percival Lowell] [plmars2-texture-v3.jpg]

This texture was created from the image shown above using ImageMagick, NetPBM, Painter Classic and a Wacom drawing tablet.

8: Maps from the Mars Orbital Laser Altimiter (MOLA)
Celestia screenshot Surface texture map Comment
For more information about the results from the Laser Altimeter mission, please visit http://svs.gsfc.nasa.gov/stories/MOLA/ The textures below were generated by croping and scaling images provided on the Web by NASA. The original TIFF format maps were the result of work by NASA - Goddard Space Flight Center, Scientific Visualization Studio, Television Production NASA-TV/GSFC, and The MOLA Instrument and Science Team.

9: Mars: MGS-TES minerology maps

The color maps below, which include MOLA relief shading, are scaled down from images on the Web page http://marsoweb.nas.nasa.gov/dataViz/datamaps.html

The grey maps below, which include no relief shading, are scaled up from images on the Web page http://marsoweb.nas.nasa.gov/landingsites/mer2003/datamaps.html

The data for these maps originate with the Mars Global Surveyor Thermal Emission Spectrometer group in the Department of Geological Sciences at Arizona State University.

Full references for the original TES maps are at http://marsoweb.nas.nasa.gov/landingsites/mer2003/notes/tes_mineral.html.

The color map above was "normalized" to accentuate the fainter details, especially those in the hematite map.

10: Martian Cartographic images from PDS
The 2048X1024 textures below were generated by slightly scaling down 6 pixel/degree "simple cylindrical projection" maps generated on the Web by the USGS "PDS MAP-A-PLANET" site at http://pdsmaps.wr.usgs.gov/maps.html The resulting images and texture maps below are abnormally smooth because of the subsampling done by the PDS site when generating the relatively low resolution images.
