LiDAR Point Cloud Data Distribution and Processing

• Flathead Lake Biological Station, MT (May 2005)
NCALM Project. PI: Mark Lorang, The University of Montana- Missoula. The survey area is an 90 square kilometer box located 40 km northeast of Kalispell, Montana This area was flown on May 29, 2005 and completed on May 30, 2005. Lidar data from the Nyack Floodplain on the Middle Fork of the Flathead River was collected for several purposes. The first was to provide a base image from which we could place a network of groundwater wells. The data was also used combination with optical remotes sensing data, both airborne and satellite, to identify pixels within multispectral optical imagery that corresponded to various vegetation height elevations. Those pixels were then separately classified by vegetation type. Data was also used to conduct simple flood inundation modeling of the floodplain and in combination with measures of flow depth and velocity extracting water surface elevation from the lidar to map the spatial distribution of stream power. This area has a repeat survey from Spetember 2005: Flathead Lake Biological Station, MT (September 2005).

• North Carolina Coast: Quantifying Patterns of Coastal Change (June 2006)

NCALM Project. PI: Sara Tebbens, Wright State University. This LiDAR survey was conducted over the North Carolina Outer Banks between Cape Lookout and Manteo on June 22, 2006 (GPS Day 173). The survey window needed to be optimized for both a low PDOP (strong satellite geometry) and low tide, with low tide being more essential. Both of these objectives were successfully met as best as possible. Low tide at Cape Hatteras on June 22 (06/22/2006) was 11:02AM LDT and was predicted at -0.2 L. Our survey time was from 10:10 AM  1:30 PM which included degraded PDOP from 12:15  12:45, but was otherwise good.

Three flight passes were required to cover the coastline. The coastline was flown by eye since navigation waypoints for this project were not provided. Data available through OpenTopography were collected at a low pass height (600 meters). This area was re-surveyed in July 2007 and data are available through OpenTopography: North Carolina Coast: Quantifying Patterns of Coastal Change (July 2007)

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

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 aerial LiDAR data, DEM and orthophotography raster data are available for this area: San Simeon DEMs and Orthophotos.

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 aerial LiDAR data, DEM and orthophotography raster data are available for this area: Diablo Canyon DEMs and Orthophotos.

• Pahrump Valley: California/Nevada State Line
NCALM. PI: Brian Wernicke, Caltech and Bernard Guest, University of Calgary. The survey area consisted of three 500 meter wide corridors near the California-Nevada border and across the Pahrump Valley. The corridors total approximately 60 km long, 0.5 to 1 km wide and contained approximately 40 square km. Please note that the flight was conducted in an unconventional way as this was an add-on to other work and was done to quickly obtain data for the requested area. Rather than flying a regular, straight grid across the area, the airplane banked along the determined trajectory. This way of gathering data introduces noticeable error, especially on the fringes of the flight path, giving a "corduroy" appearance to the data. This is in addition to the background periodic fine scale elevation variation (normally 5 to 20cm) which is a property of the Optech LIDAR system, and within the machine's error limits. This effect is less noticeable in Corridor 1 as the plane was following a mostly straight trajectory. Our understanding is that if these preliminary data looked promising, a carefully planned survey would then be conducted if funding became available. Bare-earth extraction was not performed on this dataset due to the scarceness of vegetation in the interest area. Filtering the data with a conservative feature preserving algorithm (Hagerud) can remove some of the vegetation but with the expense of smoothing out some of the morphology in steep areas.

• New Madrid Seismic Zone
The New Madrid Seismic Zone (NMSZ) has been responsible for producing some of the largest intraplate earthquakes on record (Tuttle et al., 2002). Paleoseismologic studies of sand blows and the Reelfoot fault show that earthquakes occurred in the last 4000 years at intervals of approximately 400-600 years (Kelson et al., 1995; Tuttle et al., 2002; Holbrook et al., 2006). The 1811-1812 NMSZ sequence produced three major earthquakes (M 7-8) followed by several large aftershocks and hundreds of smaller ones, resulting in a felt area that reached the east coast of the United States and caused destruction of several settlements along the Mississippi River due to liquefaction and strong shaking (Nuttli 1973, Johnston and Schweig, 1996). The risk of another large destructive earthquake in this region is of great concern to the USGS and local and federal authorities because several large metropolitan areas (Memphis, Little Rock, Nashville, St. Louis), and hundreds of smaller communities lie in or near the NMSZ.

The mechanism for occurrence of earthquakes in the NMSZ is widely debated. Studies reveal the NMSZ is underlain by a failed rifting event, dating from late Precambrian. During the failed rifting event, emplacement of mafic plutons throughout the crustal column took place. Further studies show a correlation between the rift and current seismic activity. This correlation suggests that the source of the earthquakes was from slippage along weak zones within the failed rift caused by the E-W compressive stress of the region, a result of plate motion. Seismic monitoring shows that there is a spatial correlation of the active seismic zone with the failed Reelfoot Rift.

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.

The requested area of interest (AOI), excluding the actual lake, was 232,536 acres of delivered LiDAR data. The LiDAR survey used two Leica ALS50 Phase II laser systems mounted in a Cessna Caravan 208B. The Leica systems were set to acquire ≥ 83,000 - 105,900 laser pulses per second (i.e., 83 - 105.9 kHz pulse rate) and flown at 900 - 1300 meters above ground level (AGL) depending on weather and terrain, capturing a scan angle of ±14° from nadir. These settings were developed to yield points with an average native pulse density of >8 pulses per square meter over terrestrial surfaces. The resulting average first-return density of delivered dataset is 11.82 points per square meter with an average ground point density of 2.26 points per square meter. The vertical accuracy was estimated at 3.5 cm RMSE. All TRPA LiDAR data is in the public domain.

• Oregon Department of Geology and Mineral Industries Lidar Program Data
DOGAMI has been supervising and coordinating the collection of large swaths of high resolution, high accuracy lidar data in Oregon and adjacent states since 2006. Following a successful 2500 mi² consortium effort in the Portland urban area, the Oregon legislature designated DOGAMI as the lead agency for lidar acquisition in Oregon. DOGAMI used a nationwide selection process that resulted in a state price agreement (OPA 8865) with Watershed Sciences Inc. of Corvallis, Oregon. The price agreement specifies data collection (8 pulse/m², Z_error < 12cm RMSE) and product standards (LAS points, 3ft or 1m bare earth and highest hit DEMs, 1.5ft intensity images, metadata) with a pre-determined unit cost to DOGAMI based on the size of the project area. Since developing OPA 8865 in April 2008, DOGAMI has ordered 13 large lidar flights, totaling 17,500 mi², has taken final delivery of 16,000 mi² of data. Funding for these projects has come from consortia organized by DOGAMI that include several dozen Federal, State and local government agencies, non-profits and public utilities. The data quality for all projects that DOGAMI has completed under OPA 8865 has been consistently excellent, substantially exceeding the minimum specifications. All DOGAMI lidar data is in the public domain, please reference DOGAMI as the data source.

All DOGAMI lidar program data are systematically evaluated for:
Completeness and useability by loading all files; swath to swath consistency by using TerraMatch to compare elevations of millions of coincident points from adjacent swaths, all values to date < 5cm; absolute vertical accuracy by comparing delivered DEMs to an large independent set of RTK GPS control points collected by DOGAMI, all values to date < 7cm RMSE; grid artifacts by visual examination of hillshade and slopeshade images of all bare earth and highest hit DEMs.

These LiDAR data were collected on September 27, 2005, for the NOAA Fisheries Service - Northwest Fisheries Science Center as part of the ISEMP (Integrated Status and Effectives Monitoring Program) for the Columbia Basin. Data collection and processing were performed by Watershed Sciences. The flight covered 122 km² and 26 river kilometers of Bridge Creek, a tributary to the John Day River in central Oregon. The flight was used as a baseline survey for the Bridge Creek Intensively Monitored Watershed, which is nested in the broader Status and Trend Monitoring in the John Day Pilot Basin.

Channel incision within Bridge Creek IMW, OR, has degraded instream and floodplain habitat leading to a loss of spawning and rearing habitat, increased summer stream temperatures and reduced base flows impacting steelhead using this system. ISEMP is collaborating with the National Park Service, NOAA-Fisheries, and the Bureau of Land Management on a restoration project that will accelerate natural recovery rates of the processes that create and maintain steelhead habitat to substantially increase steelhead productivity within the drainage.

• El Mayor-Cucapah Earthquake Rupture Terrestrial Laser Scan-Site 2
This dataset captures primary rupture features along a ~200m long stretch of the 4 April 2010 M 7.2 El Mayor-Cucapah earthquake rupture in northern Baja California, Mexico. This dataset covers in higher resolution sections of the rupture captured by the El Mayor-Cucapah Earthquake (4 April 2010) Rupture LiDAR Scan. The scans were collected along the northern Borrego fault in a single day (20 April 2010) 16 days following the earthquake. This particular dataset covers a section of the rupture along a bedrock rangefront where displacements are highly concentrated along a single fault, with some localized antithetic normal slip. Depending on how the data is processed and visualized, cm- to m-scale fault scarps, fault free-face striations, displacements defined by offset geomorphic features and cm-scale alluvial fan textures, and a paleo-fault scarp are all visible. Vegetation classification was performed manually in an immersive 3D virtual reality CAVE. This dataset includes intensity-scaled point-coloring. Surveyors: Peter Gold and Austin Elliott, UC Davis
