Open access to high-resolution, Earth science-oriented topography data, and related tools & resources. US National Science Foundation supported. #lidar https://www.opentopography.org
For the last several decades, scientists have been developing a way to make our maps more reliable with point cloud data collected by lidar. Lidar is an accurate method that helps scientists to map cities, landscapes, and places that were previously difficult or dangerous to access.

The Martian Mega-Volcano
The tallest volcano on Earth, Hawaii's Mauna Kea, pales in comparison to Olympus Mons on Mars, the largest volcano in the solar system. See what we can learn by studying the topography of planetary bodies.
