Tidally Coordinated Shoreline
A dataset representing the shorelines of tidally influenced areas of New York City. This dataset is derived from the 2017 Light Detection and Ranging (LiDAR) data capture. In most areas, LiDAR was captured during low tide (defined here as a range between Mean Lower Low Water (MLLW) and MLLW + 30% of the mean tide range). All bathymetric LiDAR and most near-infrared (NIR) LiDAR was captured during low tide. Flights flown over NIR LiDAR shoreline areas that are largely made up of sea walls and riprap were not flown during low tide. Tidal gauges used to determine low tide: Kings Point, Bergen West, Sandy Hook, and The Battery. See dataset attributes for which areas are tidally-coordinated.
