These files contain topographic and bathymetric lidar data collected by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the coast of Alabama. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera and a hyperspectral imager on a single remote sensing platform for use in coastal 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). Native lidar data is not generally in a format accessible to most Geographic 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. The 3-D position data are sub-divided into a series of products, with each covering approximately 5 kilometers of shoreline.
This dataset is a further processed subset of another data set in the NOAA Data Access Viewer (DAV). That data set is named 2010 USACE NCMP Topobathy Lidar: Gulf Coast (AL, FL). This newer subset data reflects JALBTCX (not contractor collected) bathy data that was not included in the original data and removes topo data that was in the original data that was collected with the green laser.
These data were collected as a part of the NCMP to depict the elevations above and below the water for the Alabama coastal zone.

The Data Access Viewer (DAV) allows a user to search for and download elevation, imagery, and land cover data for the coastal U.S. and its territories. The data, hosted by the NOAA Office for Coastal Management, can be customized and requested for free download through a checkout interface. An email provides a link to the customized data, while the original data set is available through a link within the viewer.

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 0.75 m at 1 Sigma.
The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.20 m at 1 Sigma.
The data provided in this file were tested against ground truth data. At these locations the lidar data matched within 0.20 meters, and different flight line data agreed within 0.20 meters.

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 9 kHz, bathymetric lidar data at 1 kHz 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.

ASCII data was then loaded and converted to LAS using GeoCue.

The NOAA Office for Coastal Management (OCM) received 6 files in laz 1.2 format. The files contained lidar elevation measurements for the project area. Horizontal positions were provided in geographic coordinates, referenced to the North American Datum of 1983. Vertical positions were provided in ellipsoid elevations and in meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes:
1. The LAStools software scripts lasinfo and lasvalidate were run on the laz files to check for errors.
2. An internal OCM script was run to check the number of points by classification and by flight ID and the gps and intensity ranges.
3. Internal OCM scripts were run on the laz files to assign the geokeys, to sort the data by gps time and zip the data to database and to http.
