OpenTopography is pleased to announce the release of three new datasets covering areas of California, and Mexico. Two of the three datasets were collected as part of NCALM's seed grant program. NCALM is an NSF-funded center that supports the use of airborne laser mapping technology (a.k.a. lidar) in the scientific community and is jointly operated by the Department of Civil & Environmental Engineering, Cullen College of Engineering, University of Houston and the Department of Earth and Planetary Science, University of California, Berkeley. OpenTopography is the primary distributor of NCALM data.
Get the data:
Alteration of Groundwater Flow due to Slow Landslide Failure, CA
Paleo-Outburst Floods in the Truckee River Canyon, CA
Lidar Transects along Yucatan Peninsula and San Gervasio, Mexico (Indefinite embargo. Data may be available for other applications at the discretion of the PI.)
Hillshades of digital terrain models (DTMs) derived from 532 nm (figure A) and 1064 nm (figure B) laser wavelengths in Truckee, CA. Figure C shows the difference between the two DTMs to highlight the river bathymetry and where the 532nm wavelength penetrated the water column. Areas in red indicate where the 1064 nm laser measured the water surface, while the 532 nm laser measured the terrain below the water surface (bathymetry)
