A method for making high-resolution maps of planetary surfaces has been found by researchers.
Laser altimeters, which measure altitudes at a lower resolution than cameras, make it difficult to map the moon's surface in detailed resolution. It's not easy to translate photographs into heights and depths.
A new method combines topographic data with degrees of shading of sunlight to provide more accurate assessments of landforms and structures. Both astronauts and robotic explorers will benefit from the development.
NASA spotted the crash site of the rogue rocket.
The new method was developed by a graduate student at the University of Copenhagen.
Combining different sources of data in different resolutions presents a big mathematical problem. The problem was narrowed down to whether an equation could solve it by the two people who worked on it.
According to the statement, they found a "mathematical key to a door that had been closed for many years."
According to the researchers, the new approach requires less computational power and is quicker than previous methods.
The technique was shown on the moon. The authors of the paper claim that they were able to increase the resolution of the topography from 200 feet to 60 meters.
The method can be used to extract precise topographic details on rock formations on planetary bodies such as the moon, Mars, asteroids and any other worlds, according to the authors.
The method can be used to find geologically interesting sites, determine the safety of astronauts, and apply it to images from satellites.
The research is described in an article in the journal.
