48095 NJ_Northern_metadata Data Set Published / External 37230 Inundation Project Completed 2016-08 These data were created as part of the National Oceanic and Atmospheric Administration Office for Coastal Management's efforts to create an online mapping viewer called the Sea Level Rise and Coastal Flooding Impacts Viewer. It depicts potential sea level rise and its associated impacts on the nation's coastal areas. The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at sea level rise and coastal flooding impacts. The viewer is a screening-level tool that uses nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help gauge trends and prioritize actions for different scenarios. The Sea Level Rise and Coastal Flooding Impacts Viewer may be accessed at: https://coast.noaa.gov/slr. This metadata record describes the New Jersey, Northern digital elevation model (DEM), which is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management's Sea Level Rise and Coastal Flooding Impacts Viewer described above. This DEM includes the best available lidar known to exist at the time of DEM creation that met project specifications. This DEM includes data for Bergen, Essex, Hudson, Middlesex, Passaic, Somerset, and Union Counties. The DEM was produced from the following lidar data sets: 1. 2015 USGS Delaware Valley 2. 2014 USGS New Jersey CMGP Sandy 3. 2008 USGS/NJDEP New Jersey Statewide Lidar: Somerset County 4. 2006-2007 NGA Lidar: Metro New Jersey The DEM is referenced vertically to the North American Vertical Datum of 1988 (NAVD88) with vertical units of meters and horizontally to the North American Datum of 1983 (NAD83). The resolution of the DEM is approximately 3 meters. The NOAA Office for Coastal Management has developed high-resolution digital elevation models (DEMs) for use in the Office's Sea Level Rise and Coastal Flooding Impacts internet mapping application. These DEMs serve as source datasets used to derive data to visualize the impacts of inundation resulting from sea level rise along the coastal United States and its territories. 10952 Source data and their associated metadata are available at the following URLs: 1. 2015 USGS Delaware Valley Metadata: http://viewer.nationalmap.gov/basic Data Download: http://viewer.nationalmap.gov/basic 2. 2014 USGS New Jersey CMGP Sandy Metadata: http://viewer.nationalmap.gov/basic Data Download: http://viewer.nationalmap.gov/basic 3. 2008 USGS/NJDEP New Jersey Statewide Lidar: Somerset County Metadata: http://viewer.nationalmap.gov/basic/?category=nedsrc&bbox=-74.7980305,40.3732000,-74.4994749,40.7594000&q=NJ_SOMERSETCO_2008 Data Download: http://viewer.nationalmap.gov/basic/?category=nedsrc&bbox=-74.7980305,40.3732000,-74.4994749,40.7594000&q=NJ_SOMERSETCO_2008 4. 2006-2007 NGA Lidar: Metro New Jersey Metadata: http://viewer.nationalmap.gov/basic Data Download: http://viewer.nationalmap.gov/basic Spatial_Reference_Information: Horizontal_Coordinate_System_Definition: Geographic: Latitude_Resolution: 0.000027 Longitude_Resolution: 0.000027 Geographic_Coordinate_Units: Decimal degrees Geodetic_Model: Horizontal_Datum_Name: North American Datum of 1983 Ellipsoid_Name: Geodetic Reference System 80 Semi-major_Axis: 6378137.000000 Denominator_of_Flattening_Ratio: 298.257222101 Vertical_Coordinate_System_Definition: Altitude_System_Definition: Altitude_Datum_Name: North American Vertical Datum of 1988 Altitude_Resolution: 0.001 Altitude_Distance_Units: meters Altitude_Encoding_Method: Explicit elevation coordinate included with horizontal coordinates Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > GEOMORPHIC LANDFORMS/PROCESSES > COASTAL PROCESSES > FLOODING Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > GEOMORPHIC LANDFORMS/PROCESSES > COASTAL PROCESSES > SEA LEVEL CHANGES Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION > DIGITAL ELEVATION/TERRAIN MODEL (DEM) Theme ISO 19115 Topic Category elevation Spatial Global Change Master Directory (GCMD) Location Keywords CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > NEW JERSEY Theme Bathymetry/Topography Theme DEM Theme Digital Elevation Model Theme elevation Theme flooding Theme inundation Theme lidar Theme sea level rise Theme topography Spatial Bergen County Spatial Essex County Spatial Hudson County Spatial Middlesex County Spatial New Jersey Spatial Passaic County Spatial Somerset County Spatial US Spatial Union County Office for Coastal Management Charleston SC Data Set None Planned Image (digital) Any conclusions drawn from the analysis of this information are not the responsibility of the NOAA Office for Coastal Management or its partners.

Contact Tyler Christensen (NOS) for details. 2018-02-08 Partial upload of Positional Accuracy fields only. The DEM is derived from the source lidar data. Horizontal accuracy testing is not performed on the DEM. Lidar source data assumed to meet 1 meter horizontal accuracy. The DEM is derived from the source lidar data. Vertical accuracy is not tested on the DEM. Project specifications require all source lidar data used in constructing the DEM to meet FEMA Specifications for Flood Hazard Mapping. A visual qualitative check was performed to ensure data completeness. All available lidar data known at the time of DEM creation that meets project specifications has been used to develop the DEM. Known data gaps may exist where lidar coverage was incomplete. Data covers the tile scheme provided for the project area. Elevation data checked for anomalous elevation values outside expected range. 1 The source elevation datasets listed above were identified, downloaded, edited, and finalized. 2016-01-01T00:00:00 2 Source elevation data and their associated hydro-breaklines, where available, were downloaded. Data were then reviewed and edited to meet the project's requirements. The major requirements were delineating streams 10m or greater in width, removing bridges over streams greater than 10m wide, flattening inland water bodies, and converting data referenced to an older geoid to the current geoid, Geoid 12B. NOAA's VDatum datum conversion tool was used to convert geoids. Ocean-connected water areas were removed from data prior to final mosaicking. Data were then mosaicked together based on date, with the most recent data taking priority. Ocean-connected water areas were given a value of -99 to standardize this area's value across sources, to flatten water for mapping, and to make it easy for users to remove ocean-connected water if desired. 2016-01-01T00:00:00 gov.noaa.nmfs.inport:48095 Anne Ball 2017-11-14T14:15:18 SysAdmin InPortAdmin 2023-05-30T18:09:30 2018-02-08 Office for Coastal Management OCM 1002 Public No No 2018-02-08 1 Year 2019-02-08
