2010 U.S. Geological Survey Topographic LiDAR: Atchafalaya Basin, Louisiana
browse graphicThe Light Detection and Ranging (LiDAR) dataset is a survey of the Atchafalaya Basin in south-central Louisiana. The entire survey area encompasses 981 square miles. The LiDAR point cloud was flown at a nominal post spacing of 1.0 meters for unobscured areas. The LiDAR data is in compliance with the U.S. Geological Survey National Geospatial Program Guidelines and Base Specifications, Version 13-ILMF 2010. The Flightlines were acquired by Northrop Grumman, 3001 Operating Unit, which required 10 subsequent missions between December 2, 2010, and December 7, 2010. Northrop Grumman classified the data into the following ASPRS compliant classes: Class 1: Processed, but unclassified Class 2: Bare Earth Ground Class 3: Low Vegetation Class 4: Medium Vegetation (also used for manual classification of vegetation returns) Class 5: High Vegetation Class 6: Buildings and man-made structures Class 7: Noise (low or high, manually identified) Class 9: Water Class 10: Ignored Ground (Breakline Proximity) Class 13: Withheld (outliers, blunders, etc.)

Use Limitation
These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data are NOT to be used for navigational purposes.
