Welcome to the NSF Supported NCALM
Data Distribution Center .
This site provides public access to high-resolution airborne laser swath mapping data (ALSM) acquired for NCALM research projects.
A Free User Registration is required to access the data.
For each project we provide multiple visualization-only layers (including aerial imagery) and high-resolution “bare-earth” digital elevation datasets which are available for download.
The current output format is ArcINFO GRID and the maximum downloadable area is 45 sq. Km.
These features will be extended in the near future, so please check back for improvements.
After you complete the Free User Registration, you'll have access to the following projects:
NAPA River Watershed, Northern CA
South Fork EEL River, Northern CA
Dragon's Back Ridge (San Andreas Fault), CA
Tender Foot Experimental Forest - MT
Big Sky - MT
Plum Island - MA
Archibold Station - FL
Susquehanna River - MD
Potomac River - MD
St. Elias Mountains (Katalla) - AK
Silver Plume - CO
Death Valley - CA (Furnace Creek Wash)
Lake Powell - UT
Flathead Lake - MT
Death Valley - CA (N of Ubehebe Crater and Red Wall Canyon areas)
The Project Tracker web interface allows you to visualize the location and extent of the data collected by NCALM, and to access project metadata. The LiDAR coverage extent can be downloaded on your computer for off-line visualization using Google Earth.
