Title:
Continuous terrain model for water circulation studies, Barnegat Bay, New Jersey (10 meter resolution, 32-bit GeoTIFF, UTM 18, WGS 84)
Abstract:
Water quality in the Barnegat Bay estuary along the New Jersey coast is the focus of a multidisciplinary research project begun in 2011 by the U.S. Geological Survey (USGS) in cooperation with the New Jersey Department of Environmental Protection. This narrow estuary is the drainage for the Barnegat Bay watershed and flushed by just three inlets connecting it to the Atlantic Ocean, is experiencing degraded water quality, algal blooms, loss of seagrass, and increases in oxygen-depletion events. The scale of the estuary and the scope of the problems within it required a regional approach to understand and model water circulation within the bay and adjacent ocean. A continuous elevation surface (terrain model) integrating all available elevation data in the area was produced for the water circulation modeling efforts.

  2. How were the data generated, processed, and modified?
    Date: 09-May-2012 (process 1 of 13)
    STEP 1.CREATE FEATURE DATASET. Create a feature dataset "BBTerrainAll" within a file geodatabase that will store the input points and final terrain model using ArcCatalog (v.9.3.1). Feature dataset was created using the Universal Transverse Mercator (UTM) Zone 18, WGS 84 horizontal coordinate system and a vertical reference system using the North American Vertical Datum of 1988 (NAVD 88), meters.

    STEP 2:Create boundary of the computational domain used for water circulation modeling. Created the domain extent in MatLab (v. 2011b) and exported as a ArcGIS (v. 10.2.2) polygon shapefile (IntGridBffr.shp) using the geographic coordinate system (WGS 84). Projected the shapefile IntGridBffr.shp to an ArcGIS (v. 9.3.1) feature class (IntGridBndrBuff) using the UTM Zone 18 (WGS 84) coordinate system. The output feature class was loaded into the "BBTerrainAll" feature dataset. Person who carried out this activity:

    Date: 10-May-2012 (process 3 of 13)
    STEP 3: DOWNLOAD AND CONVERT HISTORICAL OFFSHORE MULTIBEAM DATA FROM THE NATIONAL OCEAN SERVICE. Five multibeam surveys were accessed using the highest resolution available, either xyz, or bathymetric attributed grid (BAG). Surveys H11495, H11455, H11456, H11241, were downloaded as point soundings from the survey Smooth Sheet or of similar density average distance between points is approximately 75-100 meters. Survey H11536 was available as 1 meter BAG files and then and resampled to 25-m grid cell resolution using the resample tool within ArcGIS (v. 10.2.2) and then exported as an x,y,z file. Finally, combined all five surveys in x,y,z format into one x,y,z file (NOAA_offshore_xyzMLLW.txt) using Microsoft Excel. Data are published using the geographic coordinate system NAD 83, and a tidal datum of Mean Lower Low Water (MLLW) These data were converted to the Universal Transverse Mercator coordinate system (WGS 84) Zone 18, and NAVD 88 vertical datum using the Vertical Transformation tool (VDatum, v. 2.3.3) produced by the National Geodetic Survey. The converted file "NOAA_offshore_NAVD88.txt" was finally converted to a point feature class (NOAA_depthsNAVD88) using the "create feature class from x y table" context menu within ArcGIS (v. 9.3.1). Finally, the "NOAA_DepthNAVD88" feature class was loaded into the "BBTerrainAll" feature dataset. Person who carried out this activity:

    STEP 4: DOWNLOAD AND CONVERT NATIONAL ELEVATION DATA. Downloaded two, one third arc-second tiles from the National Elevation Dataset using the geographic coordinate system (NAD 83) and NAVD 88 vertical datum. The tiles were clipped to the model domain (IntGridBndryBuff) and the two tiles were merged into one ArcRaster grid (NED10mClip) with output resolution of 10 meters, and a projected coordinate system of Universal Transverse Mercator (UTM) zone 18, WGS 84. The grid was then converted to a multipoint feature class (NED10_MP) using the Convert Raster to Multipoint tool in ArcGIS (v. 10.2.2) and loaded into the "BBTerrainAll" feature dataset.

    STEP 5: CONVERT 2m CSAR to 5m X,Y,Z. Convert BarnBayOFR2m.csar to BarnBayOFR5mxyz.csv using CARIS Base Editor (v. 4.1). Then created a point feature class (SWATHBath5m) from the x,y,z file using the "create feature class from x,y" context menu within ArcGIS (v. 9.3.1) and the output was loaded into the "BBTerrainAll" feature dataset.

    STEP 6: CREATE 3D polygon for Manasquan Inlet. Historical soundings were sparse in the inlet. Create new 3D Polygon feature class "ManasqnInlet3d" with a constant depth of 1.75 meters (NAVD 88) to represent the last known dredged depth of the inlet (6 feet MLLW).

    STEP 8: DOWNLOAD HISTORICAL INSHORE BATHYMETRY DATA FROM THE NATIONAL OCEAN SERVICE. Downloaded historical survey data from NOAA/NOS collected between 1934 and 1962 as the only existing recorded depths within Barnegat Bay. These soundings were used in portions of the bay and Little Egg Inlet where newer data did not cover. Data were in horizontal coordinate system of NAD 83 with a vertical datum of Mean Low Water (MLW). Each survey was converted to a point shapefile using the context menu in ArcCatalog (v. 9.3.1) for editing to remove overlapping points. Each shapefile was edited to remove soundings in locations where they overlapped with newer data covered by either the EAARL-B Lidar, or SWATHplus interferometric data. Once the shapefiles were edited, they were combined into one shapefile (NOAAPtsMLW.shp) and then converted to a x,y.z text file (NOAAPtsMLW.txt). This combined file was projected to horizontal coordinate system of UTM 18, Zone 18, WGS 84, and vertical datum of NAVD88 using the Vertical Datum Transformation tool (VDatum, v. 2.3.3) produced by the National Geodetic Survey. The difference between MLW and NAVD88 is 0.071 meters. Portions of H05615, H08672, and H08220 were not within the VDatum model boundary. Those points falling outside the boundary were referenced to NAVD88 using this 0.071 meter offset. Finally, the "NOAAInshorePtsNAVD88" feature class was loaded into the "BBTerrainAll" feature dataset Person who carried out this activity:

    STEP 9: CREATE AND BUILD TERRAIN. Using the "New-Terrain" context menu within ArcCatalog (v. 9.3.1) created a new terrain model "BBTerrainAll10m" using all input points and polygons loaded into the "BBTerrainAll" feature dataset. Added the feature classes to the terrain and built to produce "BBTerrainAll". All point files were used as multipoint features, ManasqnInlet3d was used as a "hard replace", and IntGridBndryBuff was used as a "soft clip" Person who carried out this activity:

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
  2. How accurate are the geographic locations?
    The horizontal accuracy of this terrain model is dependent on the documented accuracy (if available) of the input data, however, the horizontal accuracy of the original input points is superseded by the process of aggregating (decreasing) the resolution of the original input data in many cases.
  3. How accurate are the heights or depths?
    The vertical accuracy of this terrain model is dependent on the documented accuracy (if available) of the input data, however, the horizontal accuracy of the original input points is superseded by the process of aggregating (decreasing) the resolution of the original input data in many cases. The sounding data from historical NOAA surveys (H05615, H05893, H05870, H02616) collected between 1934 and 1936 used survey methods (horizontal angles from shore station, and sounding pole/leadline) that preclude any attempt at vertical accuracy assessment for these data.
  4. Where are the gaps in the data? What is missing?
    This raster data is created from several different source datasets with different resolutions and collection times. This dataset is clipped to a custom boundary and may not include the entire spatial extent of the input datasets as they are published in original form.
  5. How consistent are the relationships among the observations, including topology?
    Gaps exist between data points
