Resource Abstract:
- description: Light Detection and Ranging (LiDAR) data is remotely sensed high-resolution elevation data collected by an airborne
collection platform. This LiDAR dataset is a survey of areas of coastal New York, including Long Island, eastern Westchester,
and the tidal extents of the Hudson River. The 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. Specified areas of the
project were collected at a tide stage where water levels are at least 1-foot below mean sea level (MSL). This collection
was a joint effort by the NOAA Office for Coastal Management (OCM) and the New York State Department of Environmental Conservation.
The data collection was performed with three Cessna 206 single engine aircrafts, utilizing Optech Gemini sensors; collecting
multiple return x, y, and z as well as intensity data. The data were classified as Unclassified (1), Ground (2), Low Point
(Noise) (7), Water (9), Breakline Edge (10), Withheld (11), Tidal Water (14), Overlap Default (17), and Overlap Ground (18),
Overlap Water (25), and Overlap Tidal Water (30). Upon receipt, the NOAA Office for Coastal Management (OCM), for data storage
and Digital Coast provisioning purposes, converted these classifications to the following: 1 - Unclassified 2 - Ground 7 -
Low Point (Noise) 9 - Water NOAA tide gauges were used as the basis for flight planning the tidally coordinated areas. The
Stevens Institute NY Harbor Observation and Prediction System (NYHOPS) data were used to confirm accuracy of NOAA predicted
tides in Hudson. Some areas were collected using tidal restraints as listed below: Tidal Wetlands and tributary mouths selected
for tidal coordination at Mean Sea Level (MSL) minus 1 foot were: Rondout Creek Outlet; Vanderburg Cove, Moodna Creek, Constitution
Marsh, Iona Marsh, Annsville Creek, Croton River Outlet, Marlboro Marsh, Manitou Marsh, Fishkill Creek Outlet, and Wappingers
Creek Outlet. The Upper Hudson area from North of Goose Island was also collected to the same specification. Tidal Wetlands
and tributary mouths selected for tidal coordination at Mean Sea Level (MSL) were Haverstraw at Minisceongo Creek and Piermont
Marsh. On Long Island the following areas were collected at MSL: 1) the northern shore of Nassau and Suffolk counties from
approximately Glen Cove on the western boundary to Nissequogue on the eastern boundary 2) the Peconic Bay from Riverhead on
the western boundary to the east end of Shelter Island and Accabonac Harbor on the eastern boundary 3) western Great South
Bay. The remainder of the project area had no tidal restrictions for collection. LAS tiles indicate if they are tidally coordinated
or not. If tidal coordination only covers part of the tile the tile will be labeled tidally coordinated (i.e.MSL-1). In order
to post process the LiDAR data to meet task order specifications, Photo Science, Inc. established a total of 81 control points
that were used to calibrate the LiDAR to known ground locations established throughout the New York project area. Trimble
R8-3 GNSS receivers were used to complete the collection. Real Time Kinematic (RTK) survey methodology was typically performed
using the New York State Spatial Reference Network (NYSNet), a CORS/Real Time GPS Network. Additionally, control values from
various other projects completed by Photo Science in and around the project area, were used as supplemental control points
to assist in the calibration of the LiDAR dataset. The dataset was developed based on a horizontal projection/datum of UTM
NAD83 (NSRS2007), UTM Zone 18, meters and vertical datum of NAVD1988 (GEOID09), meters. Upon receipt, for data storage and
Digital Coast provisioning purposes, the NOAA Office for Coastal Management converted the data to GRS80 Ellipsoid (GEOID09)
heights, to geographic (NAD83, NSRS2007) coordinates, and from las format to laz format. LiDAR data were collected in RAW
flightline swath format, processed to create Classified LAS 1.2 files formatted to 2093 individual 750m x 750m tiles, Hydro
Flattening Breaklines in ESRI shapefile format, 1.0 meter gridded Tidal Water ERDAS IMAGINE (.img) files formatted to 670
individual 3000m x 3000m tiles, and 1.0 meter gridded V-Datum ERDAS IMAGINE (.img) files formatted to the same 3000m x3000m
tile schema. 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.; abstract:
