To delineate geologic contacts and thematically depict generalized geologic age of outcrops in Open File Report 97-470F Maps Showing Geology, Geologic Provinces, and Oil and Gas Fields of the Asia Pacific Region; Plate 2 - Southeast Asia, which is being compiled as a 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. An Arcview shapefile derived from this coverage is used in Arcview projects.

Data sources produced in this process:
All the attributes other than standard Arc/Info attributes are of character type. 1. Attribute item "GLG" is abstracted from fill colors and labels on UNESCO and BMR source maps denoting geologic age of surficial outcrops. Rock units whose age is divided within a geologic age on the map are attributed as undivided. For instance, units labeled "Q", "Q1", "Q2" and "Q3", and "Q1,2" and "Q2,3" on the UNESCO maps are attributed as "Q". Units labeled as "PgN" are attributed as "T". Units labeled on the BMR map as "Tu", "Tp" (Pliocene) and "Tm" (Miocene) are attributed as "N" (Neogene). Units labeled as "Tl", "To" (Oligocene) and "Te" (Eocene) are attributed as "Pg" (Paleogene). Units spanning Neogene and Paleogene are attributed as "T". Units colored as igneous rock of undetermined age are attributed as "und". Areas colored as surface water bodies and ocean are attributed as "H2O". Unmapped areas without color are attributed as "oth". Units denoted as uncertain with a question mark on the original maps are attributed without comment. Where there are disagreements on the original maps between the label and the fill color, or where printing errors occur, the preference is given to the label in attributing the unit. In some cases, a judgement is made according to the inferred geologic trend. Definitions for the values are found below in the entity and attribute information section. 2. Attribute item "TYPE" is abstracted from labels and fill patterns on the UNESCO and BMR source maps. Because the emphasis of this database is on oil and gas resources, igneous rocks are generalized. Acid, intermediate and basic volcanic rocks are attributed as volcanic. Acid, intermediate and basic intrusive igneous rocks are attributed as intrusive. Ophiolites and ultra basic rocks are attributed as a general class, ophiolites and ultrabasic. The UNESCO and BMR source map legends do not differentiate sedimentary from metamorphic rocks. 3. Attribute item "GEN_GLG" is calculated from the item "GLG". In those cases where the age of units span more than one geologic age, the UNESCO and BMR practice of placing the older age before the more recent age is reversed to adhere to the USGS practice of placing the more recent age first. For instance, "KT" becomes "TK". Units whose age span more than one age are attributed by the era. For example, "CmD" becomes "Pz". 4. Standard verification of attribute reliability is performed with the Arc/Info command labelerrors to find polygons without assigned character value or with more than one value. 5. Plots are created of the coverage, colored by item "GEN_GLG" and labeled by item "GLG" at the same scale, projection and map extent of each of the UNESCO and BMR source maps for the purposes of review and examination. Review was conducted by persons uninvolved in the compilation. The entire set of maps is examined with a polygon to polygon search for errors. 6. The plots are also examined by the compiler by sampling 2 degree by 2 degree areas, yielding a deductive estimate of greater than 99 percent fidelity to UNESCO and BMR source maps of items "GLG" and "TYPE", and, by extension, "GEN_GLG".
There are difficulties registering the scanned gray-scale images of the original UNESCO source maps. The latitude and longitude graticules do not match the stated map projection at the corners of the maps beyond the area mapped geologically. In particular, the upper left corner of map sheet 1, the extreme Northwest portion, and the upper right corner of map sheet 2, the extreme Northeast portion, have latitude and longitude graticules that deviate from a calculated graticule using the Arc/Info generate and project commands. Coastlines and inland water bodies abstracted from ESRI Arcworld 1:3m countries and rivers are used to rectify the images. Because international boundaries are not depicted on the UNESCO source maps, it is not possible to use borders to rectify the images. Although a relatively low RMS error is achieved in registering the images, there is little control in the Northwest portion of the coverage. The registration is inconsistent across the four map sheets used to compile this coverage. When the coverage is digitized there remain discrepencies with the ESRI sourced coverage. (ESRI Arcworld is chosen as a standard because it is widely accepted and available.) These discrepencies are in part the result of the registration problem, and in part caused by compilation differences between UNESCO and ESRI. Using a roving window, piecewise rubbersheeting is performed with the Arc/Info adjust command, polygon option. Identifiable features of inland water bodies and shorelines common to both sources are used as targets to create the "to - from" links for adjusting the coverage. The portions of this coverage depicting New Guinea and the Solomon Islands, and parts of Australia are compiled from the BMR source map and do not experience the same degree of registration problems. The latitude and longitude graticule agree closely with the calculated graticule. No rubbersheeting is perfomed on these portions. Overlaying plots of this coverage, corresponding to the source maps in scale, projection and map extent, on a light table shows a variable offset ranging from 0 to 5 mm (25 km). The following describe the tolerances of the section compiled from the UNESCO maps: 1. Original geologic maps are presumed to be of 500 meter maximum accuracy (0.1mm at 5,000,000 scale) 2. Scanned gray-scale images are of 200 dot/inch resolution (0.13 mm on paper map) 3. Scanned images are registered and rectified with an average RMS error of 641 meters. (0.1 mm on paper map) 4. Fuzzy tolerance is set at 500 meters (0.71 pixel) and weed tolerance is set at 250 meters (0.31 pixel) 5. 100 points are sampled on the master coverage for fit with ESRI Arcworld country boundaries and an RMS error is calculated of 780 meters, the maximum error is 11,400 meters. The following describe the tolerances of the section compiled from the BMR map: 1. Original geologic maps are of 500 meter maximum accuracy (0.1mm at 5,000,000 scale) 2. Scanned gray-scale images are of 200 dot/inch resolution (0.13 mm on paper map) 3. Scanned images are registered and rectified with an average RMS error of 270 meters. (0.05 mm on paper map) 4. Fuzzy tolerance is set at 500 meters (0.71 pixel) and weed tolerance is set at 250 meters (0.31 pixel)
Not Applicable
An informal threshold of 1500 meters of width or length is used in digitizing features from the source maps. This threshold is not uniformly applied. Geologic ages indicated on the source maps as uncertain or questionable are attributed without comment. Ages that are divided on the original maps are attributed as undivided. For example: two adjacent polygons of Lower and Middle Cretaceous age are digitized and attributed as one polygon of Cretaceous age. Some unusual age classifications are attributed in a more generalized or standard manner. For instance: Upper Permian through Tertiary is attributed as Cenozoic/Mesozoic, Carboniferous through Triassic is attributed as Mesozoic/Paleozoic, and Upper Triassic through Lower Cretaceous as Mesozoic. Acid, Intermediate and Basic igneous rocks are not differentiated and are attributed as either intrusive or extrusive igneous rocks. Areas indicated on the map as either Ultrabasic or Ophiolitic are classed together as Ultrabasic or Ophiolite.
Polygon topology. Each polygon has one unique label point with unique id, there are no dangles. Polygons are bounded at perimeter of extent, including areas attributed as water and where geologic age is not shown. The coverage has been topologically cleaned and built in Arc/Info 7.1.2.
