Collection Overview:

Airborne lidar collection to study the formation of evenly spaced ridges and valleys over the Gabilan Mesa in California. Further details can be found in the publication:
Perron, J. Taylor, James W. Kirchner, and William E. Dietrich. "Formation of evenly spaced ridges and valleys." Nature 460.7254 (2009): 502-505. https://doi.org/10.1038/nature08174

NOTE: The Digital Surface Model (DSM) is missing data in the North-East section of the study area. The data providers are aware of the issue, and the problem exists in the original DSM dataset. If you need DSM data in this section it is advised that you create a custom DSM from the raw lidar files here
