  7. How does the data set describe geographic features?

    Entity_and_Attribute_Overview:
    The geologic provinces data set contains AREA, PERIMETER, -ID, CODE, PNUM, and NAME. AREA, PERIMETER, and -ID are calculated internally by ARC/INFO. Each polygon in the data set was manually assigned a "CODE" which corresponds to the "PNUM" attribute which is merely a unique identifier for each of the geologic provinces.
    Entity_and_Attribute_Detail_Citation:
    A more in-depth discussion of the geologic province CODEs and their relative ranking in terms of total known petroleum volume is given in the USGS Open File Report 97-463.

Why was the data set created?

This data set provides one of the strategic tools to assist in the U.S. Geological Survey World Energy Project. This digital geologic province map was created specifically for the oil and gas assessment of selected provinces of the World. This metadata addresses only the South Asia region (Region 8) which is the subject of this cd_rom.


How was the data set created?

  1. From what previous works were the data drawn?

    none (source 1 of 1)
    Commission for Geological Map of the World, 1976, Geologic Atlas of the World: Geologic Atlas of the World, UNESCO, Paris, France.

    Type_of_Source_Media: paper
    Source_Scale_Denominator: 10000000
    Source_Contribution:
    Paper map sheet used as source for creation of the correspondent ARC/INFO geology cover.

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

    Date: Apr-1998 (process 1 of 1)
    Geologic contacts, faults, and rivers were traced from a paper 1:10,000,000 scale map on to mylar. The mylar was then scanned and loaded into ESRI's ArcInfo GIS system for cleaning and attributing. Topology was created. Attributes and contacts were verified via visual editing and review. Some attributes were combined and some polygons generalized.

  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?

    The data were derived and generalized from the Geological World Atlas, UNESCO, sheet 11, scale: 1:10,000,000 (Choubert, G. and Faure-Muret, A., 1976) and are no more accurate than that map. The attributes and contact data were reviewed by U. S. Geological Survey scientists only. Accuracy and source of attribute data is further described in the introduction on map.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

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

    Some attributes were combined and some polygons generalized because much of the detailed attribute data and polygons were not needed for this assessment project. The geologic coding scheme was based on the World Energy Project standard which incorporates geologic age, and general lithologic type. Some attribute errors may exist because of cartographic difficulties in original map and inconsistancies between source materials. Attributes and contacts were verified via visual editing and review.

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

    Based on visual inspection and review with check plots and digital image examination gross errors are eliminated. Test conducted Jan. 1998


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: none
Use_Constraints:
Polygons and line work for the geologic provinces are drawn on a digital geologic cover (reg8_glg) included on the cd-rom. The geologic base map (reg8_glg) is created from scanned images of UNESCO geologic maps of the world. These maps are paper 1:5,000,000 and 1:10,000,000 scales. The geologic province maps are not intended to be used at a scale of larger than 1:5,000,000! This map is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the International Stratigraphic Guide.

  3. What legal disclaimers am I supposed to read?

    The U.S. Geological Survey provides these geographic data "as is." The U.S. Geological Survey makes no guarantee or warranty concerning the accuracy of information contained in the geographic data. The U.S. Geological Survey further makes no warranties, either express or implied as to any other matter whatsoever, including, without limitation, the condition of the product, or its fitness for any particular purpose. The burden for determining fitness for use lies entirely with the user. Although these data have been processed successfully on computers of the U.S. Geological Survey, no warranty, expressed or implied, is made by the U.S. Geological Survey the use of these data on any other system, nor does the fact of distribution constitute or imply any such warranty. In no event shall the U.S. Geological Survey have any liability whatsoever for payment of any consequential, incidental, indirect, special, or tort damages of any kind, including, but not limited to, any loss of profits arising out of use of or reliance on the geographic or geologic data or arising out of the delivery, installation, operation, or support by the U.S. Geological Survey.

  4. How can I download or order the data?

  5. What hardware or software do I need in order to use the data set?

    To use the coverage data you must have ARC/INFO version 7.0.4 or ArcView version 3.0 or greater installed. If you do not have either ARC/Info or ArcView other similar data sets are available in Adobe Systems Inc. Portable Document Format (TM) (PDF). However, you must first download and install the Adobe(R) Reader which is available at no charge from Adobe Systems, to view and print these data sets.
