Frequently-anticipated questions:

What does this data set describe?
    Title: Geologic Provinces of the Caribbean Region (prv6bg)
    Abstract:
    This dataset includes a modified subset of polygon features that describe U.S. Geological Survey's defined geologic provinces of the World. Each province has a set of geologic characteristics that distinguish it from surrounding provinces. These characteristics may include dominant lithologies, the age of the strata, and/or structural type. Each province is assigned a unique numeric code and may fall within two or more countries or assessment regions.
    Supplemental_Information:
    Polygons were modified from the U.S. Geological Survey's World Energy Petroleum Assessment of 2000. Attributes from the 2000 assessment were transferred to the modified features.

Why was the data set created?
This dataset is intended to delineate geologic provinces of the Caribbean region.

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

    Date: Jan-2004 (process 1 of 5)
    Existing coverage (from earlier processes) for World Petroleum Assessment 2000 clipped based on extent of Caribbean region map product.

    Date: Jan-2004 (process 2 of 5)
    Hard-copy map at a printed scale of 1:2,670,000 with associated surface geology, faults, and bathymetry for use as guide to delineate new province boundaries by regional geologist. New lines drawn on map.

    (process 3 of 5)
    Map scanned and georeferenced using a first order polynomial transformation method. A good match was made between existing data in the GIS and the new image.

    Date: Feb-2004 (process 4 of 5)
    New boundaries digitized using a heads-up on-screen method. Geodatabase rules applied to remove gaps and overlaps in the polygons. All errors removed through an interative validation process.

    Date: Feb-2004 (process 5 of 5)
    Attributes joined from previous coverage to add assessment results to new boundaries. Most provinces were updated to new bathymetric information, although two new provinces were created.

  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?

    Attribute accuracy is based solely on the results of the World Petroleum Assessment 2000, USGS publication DDS-60. Modification of the province boundaries performed by Regional Coordinator, Chris Schenk. A join was performed on the dataset to incorporate existing assessment results.

    The following provinces have been added:

    6126 - Grenada Back-Arc Basin 6127 - Barbados Accretionary Complex

    The assessment results of province 6107 (Lesser Antilles Deformed Belt) were moved to province 6127 (Barbados Accretionary Complex), considering this is the same geographic extent the resource existed in previously.

  2. How accurate are the geographic locations?

    It was not possible to quantify a horizontal positional accuracy of this dataset because it is a composite dataset compiled from a variety of sources using various methodologies. The original dataset used as a guide to delineate new boundaries was compiled at an average scale of 1:5,000,000 and had a maximum accuracy of 1000 meters. New boundaries were drawn on paper map containing surface geology, faults, and bathymetry printed at a scale of 1:2,670,000. Province boundaries are drawn based on subjective interpretation and then heads-up digitized. After compilation and registration of new data, a maximum accuracy of 2000 meters was considered appropriate.

  3. How accurate are the heights or depths?

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

    Geologic provinces are delineated by U.S. Geological Survey World Energy Project Regional Coordinators and others with an emphasis on the determination of petroleum systems. Methods may vary from one region to another. In the Caribbean region, province boundaries were adjusted to more closely match surface geology and bathymetry.

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

    Polygon topology exists. Geodatabase topology rules used to identify and correct gaps and overlaps in polygon feature class. Polygons are bounded at perimeter of extent.

How can someone get a copy of the data set?
Are there legal restrictions on access or use of the data?
