Moon Rover 256P Demo Full Screen - Dev
This demo uses heightmap data to:
- To display the Moon in as much 3D detail as possible
- To enable you to explore craters and the dark side and more
May take a while to load. Page freezes while loading...
<iframe src="http://jsfiddle.net/theo/dwje1w0d/" width=100% height=500px ></iframe> #### _Sample Read PNG Composite R2 hosted on jsFiddle_Read multiple PNG files and combine
- Combines multiple heightmap PNG files into one view
- Use cursor keys to navigate
- Edit parameters in the code or use permalinks
Data hosted on GitHub pages is CORS-compatible and may therefor be accessed from any web site or server. The example above access the heightmap data on GitHub from an HTL file hosted on jsFiddle.
Needs description of the data
The use of PNG files as heightmaps solves many problems and provides many benefits/
- Data is highly compressed without loss
- Files are transmitted and cached speedily and effortlessly
- Creating mash-ups with data from multiple servers is easy and permissible
- You can actually look at the file and see something
- The scope and range of tools to process PNG files is huge

The WAC Digital Terrain Model (DTM) was constructed from WAC stereo images. This new map is called the Global Lunar DTM 100 m topographic model, or "GLD100", and covers 98.2% of the lunar surface. Using digital photogrammetric techniques the GLD100 was computed from 69,000 WAC stereo models. Due to persistent shadows near the poles it is not possible to create a complete WAC stereo map at the very highest latitudes. The GLD100 thus covers from 79° S latitude to 79° N latitude. Since the stereo correlation box is bigger than 100 meters, surface details at the 100-meter scale are not fully resolved. However, each 100-meter square has an average of 26 stereo points within it (for a planet-wide total of 100 billion points), which helps to sharpen the elevation estimate. The resolution, in a formal sense, is probably close to 300 meters, and the accuracy of the elevations is estimated to be about 10 to 20 meters (Scholten et al JGR in press).
The GLD100 is available in the original 100 meters/pixel scale format in ten tiles. The GLD100 is also available in same tile format for scales of 256 pixels per degree (ppd) and 128 ppd. The LRO Lunar Orbiter Laser Altimeter (LOLA) excels at characterizing the topography of the poles. Since the LRO orbits converge at the poles LOLA provides a very high resolution topographic model of the poles. For the 256 ppd and lower resolution formats the LOLA polar data fills in the WAC "hole at the pole".
The WAC topography was produced by LROC team members at the German Aerospace Center (DLR).
