I’ve begun a project to print lunar surface features using a rapid prototyper, or 3D printer. The Clementine data is only one kilometer per pixel. The Japanese Space Agency, JAXA, published lunar DEM, or Digital Elevation Model last week, but the only data currently available is 16 pixels per degree. A staffer on the Lunar Reconnaissance Orbiter mission kindly pointed me to the little high-resolution data available at the USGS website. The highest resolution lunar terrain model that exists and is open to the public is a model of the large area around the Apollo 15 landing site. It is about 450 km on a side, and there is a 10 meter/post version from Apollo Panoramic Camera images, and a 50 meter/post version from Apollo Metric Camera images, these models were created by the USGS. You can find the USGS models on this page: http://webgis.wr.usgs.gov/pigwad/down/moon_dl.htm
They are the 1.9 GB download labeled ‘Hadley Rille Panoramic Stereo Model.’
The above image was generated from the 50 meter/post version. The data was read into Mathematica, and the function ReliefPlot generated the image, initally ten million points and 265 meg. I saved the map as a jpeg. You can see some of this image in Google Earth, after selecting the Moon from the Planets menu and searching for Rima Hadley.
This is a 3D plot of a portion of the above data. The z direction in and out of the screen is exaggerated.
