Community Contributed Data

Community Datasets Datasets listed below were contributed to OpenTopography by members of our community. These datasets are not hosted by OpenTopography, but are shown here as a service to our users. We encourage organizations with publicly available lidar data to register these in our community contributed data catalog so that they are discoverable by OpenTopography users. These community-contributed data will appear on the data map and will be discoverable alongside data hosted by OpenTopography. All community contributed data must satisfy the OpenTopography data hosting policy.
To contribute a dataset, users must have a myOpenTopo account. Please log in or create an account to get started.
1   USGS Lidar Point Cloud NY CMPG 2013 LAS 2015
 
Description
Lidar (Light detection and ranging) discrete-return point cloud data are available in the American Society for Photogrammetry and Remote Sensing (ASPRS) LAS format. The LAS format is a standardized binary format for storing 3-dimensional point cloud data and point attributes along with header information and variable length records specific to the data. Millions of data points are stored as a 3-dimensional data cloud as a series of x (longitude), y (latitude) and z (elevation) points. A few older projects in this collection are in ASCII format. Please refer to http://www.asprs.org/Committee-General/LASer-LAS-File-Format-Exchange-Activities.html for additional information.

2   North Carolina 20 ft. DEM and County Extracts
 
Description
A seamless aggregation of the tiled 20 ft elevation DEM tiles generated by the North Carolina Floodplain Mapping Project, http://www.ncfloodmaps.com/, into a single seamless data set. Following aggregation, county extracts were generated. See http://fris.nc.gov/fris/Download.aspx?ST=NC for metatdata on accuracy of original floodplain mapping lidar data.

3   City of Surrey, British Columbia, Canada
 
Description
To support various Capital Engineering Projects, the City of Surrey conducted a comprehensive Airborne Remote Sensing data acquisition project between March and May of 2013. This data is made publically available as part of Surrey's Open Data Initiative, and is available in bulk. The following remote sensing data is available:
-High resolution Light Distance And Ranging (Lidar) Data (25+ pts/m2)
-72 Band HyperSpectral Imagery (1 metre pixel resolution)
-3 Band Orthorectified Imagery (10 cm pixel resolution)

While these data were acquired for specific capital engineering projects, there is value inherent within them that others can realize. The City will monitor innovative applications of the City's Open Data to establish the extent and frequency of future remote sensing data acquisition. Direct any questions regarding the application of this data to Bill McKay (BDMcKay at surrey dot ca or 604 591-4868). Additional information and data license is described at http://www.surrey.ca/opendata

4   B4 Project (San Andreas & San Jacinto Fault) Lidar Imagery
 
Description
Project B4 is an NSF project led by OSU and USGS scientists, and supported by NCALM and UNAVCO, that completed an Airborne Laser Swath Mapping (ALSM) survey of ~ 1,000 km of the southern San Andreas Fault and San Jacinto Fault systems in mid-2005. The purpose is to obtain pre-earthquake imagery necessary to determine near-field ground deformation after a future large event (hence the name B4), and to support tectonic and paleoseismic research. This particular data set has been gridded at ~1 meter resolution.

1   Galway Lake Road, Emerson Fault, CA
 
Description
Galway Lake Road site data was generated using Structure from Motion (SfM; not a laser scanning method). The site, located ~45 km north of Yucca Valley, covers a segment of the Emerson Fault ruptured by the 1992 Mw 7.3 Landers earthquake, and tests the feasibility of SfM as part of the immediate scientific response following an earthquake.

2   Washington Street site, Banning strand, southern San Andreas Fault, CA
 
Description
Washington Street site data was generated using Structure from Motion (SfM; not a laser scanning method). The site is located ~20 km due east of Palm Springs and covers a short section of the southern Banning strand of the San Andreas Fault that cuts through an alluvial fan and has not ruptured historically. The site serves as a test site for using SfM in paleoseismic studies.
