    Title:
    Unpublished Digital Pre-Hurricane Sandy Geomorphological-GIS Map of the Staten Island Unit, Gateway National Recreation Area, New York (NPS, GRD, GRI, GATE, STIS digital map) adapted from a Rutgers University Institute of Marine and Coastal Sciences unpublished digital data by Psuty, N.P., McLoughlin, S.M., Schmelz, W. and Spahn, A. (2014)
    Abstract:
    **THIS NEWER 2016 DIGITAL MAP REPLACES THE OLDER 2014 VERSION OF THE GRI GATE Geomorphological-GIS data. The Unpublished Digital Pre-Hurricane Sandy Geomorphological-GIS Map of the Staten Island Unit, Gateway National Recreation Area, New York is composed of GIS data layers and GIS tables in a 10.1 file geodatabase (stis_geomorphology.gdb), a 10.1 ArcMap (.MXD) map document (stis_geomorphology.mxd), individual 10.1 layer (.LYR) files for each GIS data layer, an ancillary map information (.PDF) document (gate_geology.pdf) which contains source map unit descriptions, as well as other source map text, figures and tables, metadata in FGDC text (.TXT) and FAQ (.HTML) formats, and a GIS readme file (gate_gis_readme.pdf). Please read the gate_gis_readme.pdf for information pertaining to the proper extraction of the file geodatabase and other map files. To request GIS data in ESRI 10.1 shapefile format contact Stephanie O’Meara (stephanie.omeara@colostate.edu; see contact information below). The data is also available as a 2.2 KMZ/KML file for use in Google Earth, however, this format version of the map is limited in data layers presented and in access to GRI ancillary table information. Google Earth software is available for free at: <http://www.google.com/earth/index.html>. Users are encouraged to only use the Google Earth data for basic visualization, and to use the GIS data for any type of data analysis or investigation. The data were completed as a component of the Geologic Resources Inventory (GRI) program, a National Park Service (NPS) Inventory and Monitoring (I&M) Division funded program that is administered by the NPS Geologic Resources Division (GRD). Source geologic maps and data used to complete this GRI digital dataset were provided by the following: Rutgers University Institute of Marine and Coastal Sciences. Detailed information concerning the sources used and their contribution the GRI product are listed in the Source Citation section(s) of this metadata record (stis_pre-sandy_metadata_faq.html; available at <http://nrdata.nps.gov/geology/gri_data/gis/gate/stis_pre-sandy_metadata_faq.html>). Users of this data are cautioned about the locational accuracy of features within this dataset. Based on the source map scale of 1:6,000 and United States National Map Accuracy Standards features are within (horizontally) 5.08 meters or 16.67 feet of their actual location as presented by this dataset. Users of this data should thus not assume the location of features is exactly where they are portrayed in Google Earth, ArcGIS or other software used to display this dataset. All GIS and ancillary tables were produced as per the NPS GRI Geology-GIS Geodatabase Data Model v. 2.3. (available at: <http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.cfm>). The GIS data projection is NAD83, UTM Zone 18N, however, for the KML/KMZ format the data is projected upon export to WGS84 Geographic, the native coordinate system used by Google Earth. The data is within the area of interest of Gateway National Recreation Area.
    Supplemental_Information:

Why was the data set created?
The data are intended to assist NPS personnel in the protection and management of Gateway National Recreation Area.

How was the data set created?
  1. From what previous works were the data drawn?

    IMCS unpublished digital data (source 1 of 1)
    Psuty, N.P., McLoughlin, S.M., Schmelz, W. a, 2014, Geomorphological Map for Gateway National Recreation Area (pre-Hurricane Sandy), New York and New Jersey: unpublished digital data not applicable, Rutgers University Institute of Marine and Coastal Sciences (IMCS), New Brunswick, New Jersey.

    Type_of_Source_Media: digital data
    Source_Scale_Denominator: 6000
    Source_Contribution:
    Features and attribution were derived from source digital data. Ancillary map text, including unit descriptions, and graphics, if present on the source map, were captured, formatted and added to the ancillary map PDF document. See the Process Step section for additional information.

  2. How were the data generated, processed, and modified?

    Date: 14-Sep-2016 (process 1 of 1)
    1.) GIS features were produced from source digital data. See the Source Information Contribution section(s) for specific source map details. GIS features were first imported into a GRI data model compliant geodatabase. For details on the GRI data model see the NPS GRI Geology-GIS Geodatabase Data Model v. 2.3 (available at: <http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.cfm>). 2.) Line quality was checked and if warranted edited to ensure good quality linework. 3.) Feature attribution was derived using the source data attribution, and the source printed/plotted map if available. 4.) Data Model topology rules were validated for all features and any topology errors corrected. 5.) Quality control (QC) consisted of checking features and their attribution against the source digital data, as well as against the source printed/plotted map if available. A GRI developed ArcObjects tool was run to check for GRI data model validation and feature-related consistency. 6.) The UNIT and MAP tables were populated and checked against the source (s). Relationship classes were also added and used to ensure attribution consistency between feature class and table attribution. 7.) Feature symbology was produced for all feature classes. An attempt was made to best match symbology to its source map, however, in some cases features symbology maybe slightly modified, primarily based on the limitations of the ArcGIS geology style. In some cases, however, symbology may have been modified to reconcile differences from multiple sources. 8.) GIS feature classes were exported from the geodatabase to shapefile (SHP) format, and GIS tables exported to DBASEIV (DBF) format. Layer (LYR) files were also exported. 9.) The ancillary map information PDF document, see the Supplemental Information section for additional information, was produced from textual information and figures present on the source map(s) and/or in digital data files. If applicable, source map images were produced at 150dpi or greater resolution and optical character recognition (OCR) software was used to produce text from source map text. The text, source map images and other ancillary source map information were added to a Help & Manual (HMXZ) template file. The HMXZ file was then compiled to produce the ancillary map PDF document. Any compilation errors were then checked and corrected and the document was reviewed for content, usability and grammatical errors. 10.) KML/KMZ files were produced with certain UNIT and MAP table fields appended and calculated for each feature class prior to export.

How reliable are the data; what problems remain in the data set?
  1. How well have the observations been checked?

    Feature and table attribution was derived and checked with the source map(s). Attribution was checked (QCd) for errors. Users of this data are advised to FULLY and CAREFULLY READ the "DISTRIBUTION LIABILITY" section of this metadata before using the data.

  2. How accurate are the geographic locations?

    Data was produced from digital source data. Users of this data are cautioned about the locational accuracy of features within this dataset. Based on the source map scale and United States National Map Accuracy Standards features are within (horizontally) 5.08 meters or 16.67 feet of their actual location as presented by this dataset. Users of this data should thus not assume the location of features is exactly where they are portrayed in ArcGIS or other software used to display this dataset. The PRECISION of any Shapefile (SHP) files is DOUBLE.

  3. How accurate are the heights or depths?

    No vertical coordinates are present in this GRI digital dataset.

  4. Where are the gaps in the data? What is missing?

    All data is considered complete to the extent of the source map(s).

  5. How consistent are the relationships among the observations, including topology?

    GIS data in 10.1 file geodatabase and 2.2 KML/KMZ file formats.
