Someone once told me that Mars has better elevation data than Earth. Maybe it's the quality of the orbiters or maybe it's the fact that there is less atmospheric interference and you can use LiDAR vs radar? Can anyone confirm?
bdon, if you're reading this we need a protomaps archive for the moon and Mars :)
- kvdveer 3y agoI thought that earth elevation data is unreliable in forested areas, as vegetation hides the true elevation of those areas. That's probably not a significant problem on Mars...
- tppiotrowski 3y agoI think vegetation is an issue with LiDAR but my understanding is that radar penetrates down to the ground.
- tmoravec 3y agoMy guess would be that they meant the oceans. No water = better elevation data.
