Recorded sources
4 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Mars elevation data are publicly available?

Yes. Mars elevation data, such as those gathered by the Mars Orbiter Laser Altimeter (MOLA), are publicly available and widely used in scientific studies to map surface topography and analyze geological features.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

Multiple peer-reviewed studies explicitly state or demonstrate the use of publicly available Martian elevation datasets, specifically MOLA data, to map elevations, channels, basins, and coastal features across Mars. There are no papers refuting the availability of this data.
