2011 - 2012 LiDAR Data for Sagamore Hill National Historic Site (New York State Department of Environmental Conservation (NYSDEC) Lidar)
New York State Department of Environmental Conservation (NYSDEC) and National Oceanic and Atmospheric Administration's (NOAA) Office for Coastal Management. 2015. 2011 - 2012 LiDAR Data for Sagamore Hill National Historic Site (New York State Department of Environmental Conservation (NYSDEC) Lidar). National Park Service
Classfied LAS files containing topographic LiDAR data for Sagamore Hill National Historic Site collected Fall 2011 through Spring 2012. This data set is an LAS format file containing LIDAR point cloud data with 7376861 points. The data set was generated from a larger data set and includes all valid points within the requested geographic bounds. Light Detection and Ranging (LiDAR) data is remotely sensed high-resolution elevation data collected by an airborne collection platform. This LiDAR dataset is part of a survey of areas of coastal New York, including Long Island, eastern Westchester, and the tidal extents of the Hudson River. The full project area consists of approximately 950 square miles. The project design of the LiDAR data acquisition was developed to support a nominal post spacing of 1.0 meter or better (1.0 meter GSD). The LiDAR data vertical accuracy is in compliance with the National Standard for Spatial Data Accuracy (NSSDA) RMSE estimation of elevation data in support of 1 ft. contour mapping products. GMR Aerial Surveys Inc. d/b/a Photo Science, Inc. acquired 740 flight lines in 63 lifts between November 2011 and April 2012, while no snow was on the ground, rivers were at or below normal levels, no strong onshore winds, high waves, floods, or other anomalous weather conditions. LiDAR data were originally delivered to NOAA/Dewberry for quality control validation under Delivery Lots 1 and 2. The lineage (data quality), positional, content (completeness), attribution, logical consistency, and accuracies of all digital elevation data produced conform to the specifications stipulated in NOAA Task Order EA133C11CQ0009 - T011.
