Title:
Polygon boundaries for source data of a continuous terrain model for water circulation studies: Barnegat Bay, New Jersey (Esri polygon shapefile, Geographic, 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: 2014 (process 1 of 11)
    Step 1: Create empty polygon feature class (TerrainBounds)with in a file geodatabase using ArcGIS (v. 9.3.1) to store data boundaries for the terrain model. Feature class used the Universal Transverse Mercator (UTM) coordinate system Zone 18, WGS 84 datum. Added following text attributes using ArcCatalog (v. 9.3.1) context menu "add field": "Source" and "SurvDate" Person who carried out this activity:

    Data sources produced in this process:
    • TerrainBnds
    Date: 2014 (process 2 of 11)
    Step 2: Create polygons boundaries for each of the edited historical NOAA surveys. Added the edited version of each of these surveys to ArcMap (v. 9.3.1) and added feature to "TerrainBnds" feature class by digitizing a polygon around their general extent. Survey boundaries added were: H05615, H05870, H02616, H05893 Person who carried out this activity:

    Data sources produced in this process:
    • TerrainBnds
    Date: 2015 (process 3 of 11)
    Step 3: Create polygon feature class delineating the extent of the NED10m grid. Using ArcGIS (v. 9.3.1) query grid for all values "> 0.1" which produces an 8-bit raster "NED10mMask", The raster is then converted to a polygon using the "Raster to Polygon" tool. The input raster is "NED10mMask" and the output polygon feature class is "NED10mMaskPgon". Finally, append "NED10mMaskPgon" to "TerrainBnds" feature class. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

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?
    This polygon shapefile was generated by a combination of digitizing around survey data, and converting rasters to polygons. Each feature in the shapefile encompasses the complete extent of each input dataset.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    The individual polygons only delineate the extent of bathymetric data used to compile the bathymetric terrain model and may not include all the data collected during the individual survey.
  5. How consistent are the relationships among the observations, including topology?
    Polygon boundaries were created using the spatial extent of the input files used to create the terrain model. The boundaries for the source "NED" and "USGS EAARL" attributes were created by converting the raster data directly to a polygon. The boundaries of the remaining datasets were created by digitizing a boundary polygon around the extent of each of the datasets such that adjacent polygons do not overlap.
