2010 USACE NCMP Topobathy Lidar: Alabama

Welcome Guest   ( Sign In )
NOAA
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. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
