Why was the data set created?

To delineate geologic province boundaries in Open File Report 97-470F Maps Showing Geology, Geologic Provinces, and Oil and Gas Fields of the The Far East, which is being compiled as a small scale geologic reference for the U.S. Geological Survey's World Energy Project assessment of undiscovered, technically recoverable oil and gas resources of the world. This coverage is used to produce a map and an Adobe Acrobat Portable Document of the map, to be published on CD-ROM. An Arcview shapefile derived from this coverage is used in an Arcview project.

How was the data set created?

1. From what previous works were the data drawn?

   wrldprov_rob (source 1 of 1)

   Survey, U.S.Geological, 19960000, wrldprov_rob (World Geologic Provinces in Robinson Projection): U.S. Geological Survey, Denver, CO, U.S.A..

   Type_of_Source_Media: digital file

   Source_Contribution: Boundaries, names and codes of geologic provinces

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

   Date: 01-Dec-1999 (process 1 of 4)

   wrld_rob, world wide polygon coverage of geologic provinces is projected to Lambert projection, cleaned and built with fuzzy tolerance of 500 meters.

   Date: 01-Dec-1998 (process 2 of 4)

   Polygon coverage is clipped to current extent, fuzzy tolerance of 500 meters.

   Date: 01-Feb-1999 (process 3 of 4)

   Line topology is added to polygon coverage, lines of province boundaries extending beyond mapped geology are split and attributed for purposes of cartographic display. The coverage is cleaned and built with a fuzzy tolerance of 500 meters.

   Date: 10-Feb-1999 (process 4 of 4)

   Coverage is edited with the coverage of generalized geologic age as a backdrop. Boundaries are adusted to match surface geology, where applicable, with the Arc/Info vertex move and node move commands.

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

   T.R. Klett, T.S. Ahlbrandt, J.W. Schmoker, and G, 19970000, Ranking of the World's Oil and Gas Provinces by Known Petroleum Volumes: World Energy Data on CD-ROM Open File Report 97-463, U.S. Geological Survey, Denver, CO, U.S.A..

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

1. How well have the observations been checked?

   This coverage is a portion of a composite coverage composed of geologic provinces defined by regional coordinators of the U.S. Geological Survey World Energy Project and others. There have been updates and corrections in spelling of the names of the provinces since they were first published in Open File Report 97-463 (Klett and others, 1997). The following provinces depicted in this coverage have been updated: 3108 Cuoqing Lupola Basin is now Cuoqing Lunpola Basin 3115 Jungger Basin is now Junggar Basin 3159 Yingehai Basin is now Yinggehai Basin 3403 Huskan Platform is now Huksan Platform 3404 Korba Bay Basin is now Korea Bay Basin Changes have been reviewed by regional coordinator.

2. How accurate are the geographic locations?

   Coverage has a fuzzy tolerance of 500 meters. Province boundaries are adjusted to more closely match surface geology, where applicable, since the provinces were first published in Open File Report 97-463 (Klett and others, 1997) Boundary changes have been reviewed by regional coordinator.

3. How accurate are the heights or depths?

   Not Applicable

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. The coverage has been updated. Spelling errors in province names are corrected. Province boundaries are adjusted to more closely match surface surface geology, where applicable.

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

   Polygon topology is present, each polygon has one unique label point, there are no dangles, polygons are bounded at extent of coverage. The coverage has been topologically cleaned and built in Arc/Info.

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: None
