Title: 2008 USACE/JALBTCX Lidar: Truckee River (NV)
Short Name: nv2008_usace_truckee_m3661_metadata
Status: Completed
Publication Date: 2015-01-07
Abstract:

These files contain topographic and bathymetric lidar data collected by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the Truckee River, NV. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera and a hyperspectral scanner on a single remote sensing platform for use in mapping and charting activities. Data coverage generally extends along the coastline from the waterline inland 500 meters (topography) and offshore 1,000 meters or to laser extinction (bathymetry). The topographic lidar sensor has a pulse repetition rate of 9 kHz at 1064 nm (near-infrared wavelength). The bathymetric lidar sensor has a pulse repetition rate of 1 kHz at 532 nm (green wavelength). Native Lidar data is not generally in a format accessible to most Geographical Information Systems (GIS). Specialized in-house and commercial software packages are used to process the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID03 model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). The ASCII columns are Longitude, Latitude, UTM Zone, Easting, Northing, Elevation (orthometric), Elevation (ellipsoid), Date, Time, and Intensity. The ASCII files were converted to LAS files at OCM when received.

Purpose:

These data were collected to depict the elevations above water along the Truckee River, Nevada.

Lineage

Process Steps

Process Step 1

CC ID: 1146733
Description:

These data were collected using the CHARTS system. It is owned by the Naval Oceanographic Office and operated through contract. The system collects topographic lidar data at 9kHz, bathymetric lidar data at 1kHz and RGB imagery at 1Hz. A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V 410 equipment. All raw data streams are transferred to the office for downloading and processing in SHOALS GCS software. Aircraft position data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. Upon inspection and QA/QC in the software packages Fledermaus and PFM_ABE, anomalous data are flagged as invalid. PFM_ABE's chartsLAS module then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID03 model and exports data as a series of first return topography (TF), last return topography (TL) and bathymetry (H) ASCII files. The bathymetry files contain all of the returns from the bathymetric sensor which include returns both above and below the water.

Process Step 2

CC ID: 1146734
Description:

The NOAA Office for Coastal Management (OCM) received unclassified topobathymetric files in LAS format. The files contained lidar elevation measurements. The data were received in North American Datum 1983 (NAD83) geographic coordinates and were vertically referenced to NAVD88 using the Geoid03 model. The vertical units of the data were meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes:

1. The topobathy ASCII files were converted from text files to LAS files.

2. The LAS files were converted from orthometric (NAVD88) heights to GRS80 ellipsoidal heights using Geoid09.

3. Breaklines were created to attribute bathymetric points where possible (unrefracted) to NOAA OCM's Class 11 (bathymetry)

4. LASGround classified remaining unclassified points to Class 2 (ground), leaving unclassified points as Class 1 if not Ground or Bathy. (These have not been extensively reviewed for accuracy or to any standard).
