2015 NOAA NGS Topobathy Lidar DEM: Buzzards Bay Block3 (MA)

Metadata Updated: April 15, 2024

These data were collected and derived by the National Oceanic Atmospheric Administration, National Geodetic Survey (NGS) Remote Sensing Division using a Riegl VQ820G system. The data were acquired from 20151109 - 20151123. The data includes topobathy data in an ERDAS Imagine (IMG) format and a 1 m grid size. The DEM data includes utilization of ground (2), bathymetric point (26), submerged object (29), and International Hydrographic Organization (IHO) S-57 object (30) classification fields from LAS files. An automated ground classification algorithm was used to determine bare earth point classification. It should be noted that not all returns may be correctly classified; therefore the user should examine for acceptability. In addition to the DEMs, the topobathy lidar point data are also available. These data are available for download here: https://coast.noaa.gov/dataviewer/#/lidar/search/where:ID=5101 Original contact information: Contact Org: National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Geodetic Survey (NGS), Remote Sensing Division Title: Chief, Remote Sensing Division Phone: 301-713-2663

Users should not use this data for critical applications without a full awareness of its limitations.This LIDAR data set is not intended for removal of features such as wrecks, rocks and obstructions., Distribution Liability: These data have been developed from the best available sources. Although efforts have been made to ensure that the data are accurate and reliable, errors and variable conditions originating from physical sources used to develop the data may be reflected in the data supplied. Users must be aware of these conditions and bear responsibility for the appropriate use of the information with respect to possible errors, scale, resolution, rectification, positional accuracy, development methodology, time period, environmental and climatic conditions and other circumstances specific to these data. The user is responsible for understanding the accuracy limitations of the data provided herein. The burden for determining fitness for use lies entirely with the user. The user should refer to the accompanying metadata notes for a description of the data and data development procedures.
