Description:
Airborne lidar data of Wax Lake Delta, Louisiana, USA, a delta prograding into Atchafalaya Bay, Gulf of Mexico. Rasters were produced from the 2013 Airborne lidar data wherein trees and vegetation were removed. The data were then rasterized and saved to geotiff using the software package CloudCompare.

Note: The point cloud data were not initially classified for vegetation removal. As such, the investigators removed vegetation to create the raster datasets. The removal process will not match the removal from the classification performed on the data later. The later classification is uploaded to OpenTopography. To get the same rasters as the ones available on OpenTopography, start with the complete unclassified point cloud and follow the methods described in the full metadata file.

13   Boulder Creek Critical Zone Observatory May 20-21 2010 Snow-On Lidar Survey  
 
Description:
Data were collected in collaboration between the National Center for Airborne Laser Mapping (NCALM) project and the Boulder Creek Critical Zone Observatory (CZO), both funded by the National Science Foundation (NSF). The dataset contains 1 m Digital Surface Models (first-stop), Digital Terrain Models (bare-earth), and 10 points/m2 LAS-formated point cloud tiles. The DSMs and DTMs are available in GeoTIFF format with associated shaded relief models. The Digital Terrain Model (DTM) is a ground-surface elevation dataset better suited for derived layers such as slope angle, aspect, and contours. Accessory layers consist of index map layers for point cloud tiles, DEM extent, and flight lines. Other LiDAR DSMs, DTMs, and point cloud data available in this series include snow-off data for 2010. Together, the LiDAR Digital Elevation Models (DEM) and point cloud data will be of interest to land managers, scientists, and others for study of topography, snow, ecosystems and environmental change. The Boulder Creek CZO will be using the LiDAR data to further their mission of focusing on how water, atmosphere, ecosystems, & soils interact and shape the Earth's surface. The 'Critical Zone' lies between rock and sky. It is essential to life - including human food production - and helps drive Earth's carbon cycle, climate change, stream runoff, and water quality.

Read the FGDC-compliant metadata files that are available for each dataset (in .html, .txt, and .xml formats). These files provide numerous details that may be of interest. Also included are flight lines, survey reports, reference materials, and DEM extent shapefiles.

IMPORTANT NOTE: Due to weather and equipment failures the snow-on surveys were flown during 2 different time periods in May, between which there were substantial snow accumulations. Do not combine data from May 5/9, 2010 and May 20/21, 2010.

18   Marlborough Fault System, South Island, New Zealand  
 
Description:
Collaborative Research: Towards an Understanding of the Collective Behavior of Regional Fault Networks: The Marlborough Fault System, New Zealand (James F. Dolan, PI, University of Southern California). This project was a collaborative effort between PI Dolan (USC) and co-I Ed Rhodes (UCLA) and New Zealand collaborators Russ Van Dissen and Rob Langridge of GNS Science. The survey area consists of a total of 254 km of fault-parallel, predominantly ~1.2-km-wide swaths along parts of the four main right-lateral strike-slip faults that comprise the Marlborough Fault System, in the northwestern portion of New Zealand's South Island. The five fault segments surveyed include sections of the eastern and western parts of the Clarence fault, the central part of the Awatere fault, the central part of the Wairau fault, and part of the eastern (Conway) segment of the Hope fault. These lidar data facilitated detailed analysis of fault offsets along the four main MFS faults, as well as mapping of small displacements that have occurred in recent earthquakes on Marlborough faults in unprecedented detail, the geomorphic development and evolution of fluvial terraces crossing these faults, and the progressive geomorphic manifestation of off-fault deformation with increasing fault displacement. The data were analyzed by the PIs, our New Zealand collaborators, and three graduate students at USC (Robert Zinke, Alexandra Hatem, and Jessica Grenader), and one graduate student at UCLA (Chris McGuire [supervised by Co-I Ed Rhodes]); their results will form major parts of their graduate theses. The lidar data were collected by U.S. National Center for Airborne Laser Mapping (NCALM) personnel using an aircraft and flight personnel subcontracted from New Zealand Aerial Mapping. The data were collected with a combination of NCALM's Optech GEMINI sensor (operated at a laser pulse frequency of 125 kHz in multi-pulse mode, at a nominal height above ground of 1400 m) and NZAM's Optech 3100A sensor (operated at a laser pulse frequency of 70-100 kHz at various heights depending on terrain). Shot density is ≥ 12 shots/m2. The lidar data were utilized in our studies of the incremental slip-rate record of the four main Marlborough faults. The lidar data also provided a means of mapping small displacements that have occurred in recent earthquakes on Marlborough faults in unprecedented detail, the sedimentological development and geomorphic evolution of fluvial terraces crossing these faults, and the progressive geomorphic manifestation of off-fault deformation with increasing fault displacement (see Zinke et al., 2015 Geology for a discussion of this latter topic [doi:10.1130/G37065.1]).

19   NEON D17 Pacific Southwest- California  
 
Description:
NEON field sites surveyed: San Joaquin Experiment Range (SJER), Soaproot Saddle (SOAP), Providence Creek (PROV), and Teakettle (TEAK) Geographic Characteristics: The primary objectives of the 2013 combined airborne and field campaign were to test flight operations and nominal flight collection parameters and obtain a dataset supporting spatial/temporal scaling studies underway as part of NASA's HyspIRI Airborne Campaign. AOP surveyed three NEON terrestrial sites and one aquatic site located in central California, extending over a large elevation/climate gradient from the southern foothills to the mixed conifer forest zone of the Sierra Nevada. These sites cover diverse ecological sub-regions ranging from open woodland dominated by oaks and foothill pine at the San Joaquin Experiment Range core site (SJER), mixed conifer/deciduous forest at the Soaproot Saddle relocatable site (SOAP) and Providence Creek aquatic site (PROV), and red fir forest at the Teakettle relocatable site (TEAK). Supporting ground measurements of field spectral data, vegetation structure data, and foliar samples were made in a subset of sites and in conjunction with the airborne observations. For full details about this campaign, read NEON Technical Memo TM-005. - See more at: Neon Inc.

The NEON Level 1 Slant Range Waveform LiDAR data product, NEON.DOM.SITE.DP1.30001, provides a geolocated waveform for each laser pulse in a binary output format. Waveform data is available for the San Joaquin Experiment Range (SJER), Soaproot Saddle (SOAP), and Teakettle (TEAK) field sites via the following links:

31   UMD-NASA Carbon Mapping /Sonoma County Vegetation Mapping and Lidar Program  
 
Description:

This survey covers all of Sonoma County as well as two small portions of southern Mendocino County. Data were provided by the University of Maryland and the Sonoma County Vegetation Mapping and Lidar Program under grant NNX13AP69G from NASAs Carbon Monitoring System (Dr. Ralph Dubayah, PI). The Sonoma County Vegetation Mapping and Lidar Program is NASA/UMDs local partner in this project- its members are as follows: the Sonoma County Agricultural Preservation and Open Space District, the Sonoma County Water Agency, the California Department of Fish and Wildlife, the United States Geological Survey, the Sonoma County Information Systems Department, the Sonoma County Transportation and Public Works Department, the Nature Conservancy, and the City of Petaluma.

These data will be used for various research projects throughout Sonoma County. They are critical to assessing climate mitigation and adaptation strategies and benefits provided by the landscape, such as the amount of carbon sequestration in forests or the degree to which riparian areas, floodplains, and coastal habitats may buffer extreme weather events. Other research applications include groundwater, ecosystem services valuation, ecosystem resiliency, and wildlife habitat connectivity. Finally, these data sets are key to facilitating good planning and management for watershed protection, flood control, fire and fuels management and wildlife habitat conservation.

The data was collected between September 28 and November 26, 2013 by Watershed Sciences, Inc. (WSI). Lidar was collected at high density greater than 8 pulses per square meter. WSI used two airplanes, one carrying a Leica ALS50 and the other a Leica ALS70; systems were flown at 900 meters above ground level, capturing a scan angle of 15 degrees from nadir (30 degree field of view). 4-band, 6-inch resolution aerial photography was collected simultaneously with the Lidar data.

46   PG&E Diablo Canyon Power Plant (DCPP): San Simeon, CA Central Coast  
 
Description:

The Diablo Canyon Power Plant (DCPP) Lidar and Imagery datasets are comprised of three separate Lidar surveys: Diablo Canyon (2010), Los Osos (2011), and San Simeon (2013).

The DCPP San Simeon project study area is located primarily in San Luis Obispo County, California, encompasses approximately 195,000 acres (801 km2), and measures 75 miles in length. Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (Lidar) data and orthophotography across the DCPP San Simeon survey area from 29 January 2013 to 25 February 2013. For optimal capture of the intertidal zone, WSI acquired Lidar data of the coastline during seasonal low tides between 7 February 2013 and 10 February 2013.

The lidar survey utilized a Leica ALS70 sensor in a Cessna Caravan, and an Optech Orion sensor in a Bell Long Ranger. The Leica system was used for acquisition of the inland portion of the study area. It was set to acquire 240,000 laser pulses per second (i.e., 240 kHz pulse rate) and flown at 1,100 meters above ground level (AGL), capturing a scan angle of ±15° from nadir. The Orion system was used to acquire the intertidal portion of the study area. It was set to acquire 175,000 laser pulses per second and flown at 300 meters AGL, capturing a scan angle of ±13° from nadir. Both laser systems were programmed to yield an average native pulse density of ≥8 pulses per square meter over terrestrial surfaces.

Digital orthophotos were collected using a 260 megapixel ultra large format digital aerial camera. Image radiometric values were calibrated to specific gain and exposure settings associated with each capture using Microsoft's UltraMap software suite. The calibrated images were saved in TIFF format for input to subsequent processes. Photo position and orientation were calculated by linking the time of image capture, the corresponding aircraft position and attitude, and the smoothed best estimate of trajectory (SBET) data in POSPAC. Within the Inpho software suite, automated aerial triangulation was performed to tie images together and to align with ground control. The orthophotos were delivered in 0.375 USGS tiles with a 3'' pixel resolution.

This survey was flown in conjunction with the DCPP Senior Seismic Hazard Analysis Committee (SSHAC) Level 3 process and as part of the DCPP Long-Term Seismic Program (LTSP). In addition to raster data, Lidar point cloud data are available for this area: San Simeon Point Cloud Data.

Description:

The Diablo Canyon Power Plant (DCPP) Lidar and Imagery datasets are comprised of three separate Lidar surveys: Diablo Canyon (2010), Los Osos (2011), and San Simeon (2013).

The DCPP Los Osos project study area is located in San Luis Obispo County, California, and encompasses approximately 170,000 acres (674.59 square kilometers). Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (Lidar) data across the project area from 17 March 2011 to 31 March 2011.

The lidar survey utilized a Leica ALS60 sensor in a Cessna Caravan. The Leica system was set to acquire 105,900 laser pulses per second (i.e., 105.9 kHz pulse rate) and flown at 900 meters above ground level (AGL), capturing a scan angle of ±14° from nadir when clouds and terrain permitted. With these flight parameters, the laser swath width is 449m and the laser pulse footprint is 21cm. These settings yield an average native pulse density of ≥8 pulses per square meter over terrestrial surfaces.

This survey was flown as part of the DCPP Long-Term Seismic Program (LTSP). In addition to raster data, Lidar point cloud data are available for this area: Los Osos Point Cloud Data.

Description:

The Diablo Canyon Power Plant (DCPP) Lidar and Imagery datasets are comprised of three separate Lidar surveys: Diablo Canyon (2010), Los Osos (2011), and San Simeon (2013).

The Diablo Canyon project study is located in San Luis Obispo County, California, and encompasses approximately 10,634 acres (43.03 square kilometers). Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (Lidar) data on both the inland and intertidal land within the Diablo Canyon study area on 28 January 2010. For optimal capture of the intertidal zone, WSI acquired Lidar data of the coastline during seasonal low tides (between 0.0 ft and peak low of ~ -1.5 ft) and in conjunction with a PDOP value of less than 3.0.

This Lidar survey utilized a Leica ALS50 Phase II laser system. The sensor scan angle was ±13° from nadir with a pulse rate designed to yield an average native density of ≥8 pulses per square meter over terrestrial surfaces. The area of interest was surveyed with an opposing flight line side-lap of ≥50% (≥100% overlap) to reduce laser shadowing and increase surface laser painting.

This survey was flown as part of the DCPP Long-Term Seismic Program (LTSP). In addition to raster data, Lidar point cloud data are available for this area: Diablo Canyon Point Cloud Data.

81   Boulder Creek Critical Zone Observatory August 2010 LiDAR Survey  
 
Description:
2010 Boulder Creek, Colorado Snow-Off LiDAR Surveys

LiDAR was acquired for a 600 km2 area inside the Boulder Creek watershed during a snow-off (August, 2010) time slice, near Boulder Colorado. This data was collected in collaboration between the National Center for Airborne Laser Mapping (NCALM) project and the Boulder Creek Critical Zone Observatory (CZO), both funded by the National Science Foundation (NSF). The dataset contains 1 m Digital Surface Models (first-stop), Digital Terrain Models (bare-earth), and 10 points/m2 LAS-formated point cloud tiles. The DSMs and DTMs are available in GeoTIFF format, approx. 1-2 GB each, with associated shaded relief models, for a total of 15 GB of data. The Digital Terrain Model (DTM) is a ground-surface elevation dataset better suited for derived layers such as slope angle, aspect, and contours. Accessory layers consist of index map layers for point cloud tiles, DEM extent, and flight lines. Other LiDAR DSMs, DTMs, and point cloud data available in this series include snow-on data for 2010. Together, the LiDAR Digital Elevation Models (DEM) and point cloud data will be of interest to land managers, scientists, and others for study of topography, snow, ecosystems and environmental change. The Boulder Creek CZO will be using the LiDAR data to further their mission of focusing on how water, atmosphere, ecosystems, & soils interact and shape the Earth's surface. The 'Critical Zone' lies between rock and sky. It is essential to life - including human food production - and helps drive Earth's carbon cycle, climate change, stream runoff, and water quality.

PLEASE READ the FGDC-compliant metadata files that are available for each dataset (in .html, .txt, and .xml formats). These files provide numerous details that may be of interest. Also included are flight lines, survey reports, reference materials, and DEM extent shapefiles.

1   ALOS World 3D - 30m  
 
Description:
The ALOS Global Digital Surface Model (AW3D30) is a global dataset generated from images collected using the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) aboard the Advanced Land Observing Satellite (ALOS) from 2006 to 2011. As described by the Japan Aerospace Exploration Agency: The Japan Aerospace Exploration Agency (JAXA) releases the global digital surface model (DSM) dataset with a horizontal resolution of approx. 30-meter mesh (1 arcsec) free of charge. The dataset has been compiled with images acquired by the Advanced Land Observing Satellite 'DAICHI' (ALOS). The dataset is published based on the DSM dataset (5-meter mesh version) of the 'World 3D Topographic Data', which is the most precise global-scale elevation data at this time, and its elevation precision is also at a world-leading level as a 30-meter mesh version. This dataset is expected to be useful for scientific research, education, as well as the private service sector that uses geospatial information.

Version: May 2016: Global terrestrial region (within approx. 82 deg. of N/S latitudes) of Version 1 released (approx. 22,100 tiles)

Note: JAXA provides two versions of AW3D30 created from the original 5-meter mesh using different downsampling methods: average (provided here) and median (not available from OpenTopography).

2   Shuttle Radar Topography Mission (SRTM GL1) Global 30m Ellipsoidal  
 
Description:

Note: This version of the SRTM GL1 dataset is provided in a WGS84 ellipsoidal vertical datum. This is a non-standard version of the SRTM dataset that is often used for InSAR analysis. This dataset was converted from the orthometric version using the EGM96 geoid model available here. For additional conversion details feel free to contact us.



The Shuttle Radar Topography Mission (SRTM) obtained elevation data on a near-global scale to generate the most complete high-resolution digital topographic database of Earth. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000. SRTM is an international project spearheaded by the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA).

Version 3: Elimination of the voids in the NASA SRTM DEM was the primary goal of a project under the NASA MEaSUREs (Making Earth System Data Records for Use in Research Environments) Program. Ultimately this was achieved by filling the voids with elevation data primarily from the ASTER GDEM2 (Global Digital Elevation Model Version 2) and secondarily from the USGS GMTED2010 elevation model or the USGS National Elevation Dataset (NED). NASA SRTM V3.0 three-arc-second data are provided in two forms: (1) by three-by-three averaging of the one arc-second samples, and (2) by extracting the middle sample of those same three-by-three samples.

1   Global Multi-Resolution Topography (GMRT) Data Synthesis  
 
Description:
The Global Multi-Resolution Topography (GMRT) synthesis is a multi-resolutional compilation of edited multibeam sonar data collected by scientists and institutions worldwide, that is reviewed, processed and gridded by the MGDS Team and merged into a single continuously updated compilation of global elevation data. The synthesis began in 1992 as the Ridge Multibeam Synthesis (RMBS), was expanded to include multibeam bathymetry data from the Southern Ocean, and now includes bathymetry from throughout the global and coastal oceans. GMRT is included in the ocean basemap in Google Earth (since June 2011) and the GEBCO 2014 compilation.

Data is accessed through the GMRT GridServer Web Service. OpenTopography provides a user interface for using the web service and enables users to utilize OpenTopography processing tools, such as visualization and advanced hydrologic terrain analysis (TauDEM).
