2022-2023 NOAA NGS Topobathy Lidar: Coastal Maine
The NOAA Maine Topbathymetric Lidar was collected by NV5 using Leica Chiroptera Hawkeye 4X systems. The lidar acquisitions were flown between 20221006 and 20231216 in 120 missions. The dataset includes topobathymetric data in a LAS format 1.4, point data record format 6. See the 'Lineage' section for detailed classification scheme.
This dataset also includes lidar intensity values, number of returns, return number, time, and scan angle.
After the initial data submission, NOAA reviewed the data. NV5 corrected the feedback edits and incorporated them into the dataset delivery. Additionally, green laser intensity values were normalized for depth for the dataset resulting in a full redelivery of all LAS files.
Finally, a set of normalized intensity rasters was also provided, and can be found at the Bulk Download link.
