U.S. Geological Survey <<pubdate>> KarstFaunaRegions Version 3.0, <<pubdate>> vector digital data withheld U.S. Geological Survey <<pubdate>> Geologic Database of Texas vector digital data Geologic Database of Texas <<OFR_num>> Austin, Texas Texas Water Development Board, U.S. Geological Survey RockUnitPoly250K The Texas Geologic Atlas Project was first cited in the University of Texas - Bureau of Economic Geology (BEG) Report for 1961. In September of that year, compilation of the first of 38 Geologic Atlas of Texas (GAT) hardcopy map sheets began. The project, under the direction of Dr. Virgil E. Barnes, involved the work of 28 BEG geologists and many other geologists, seven cartographers, and several editors. The last GAT sheet was published in 1987, but the GAT has remained on the BEG "Best Seller" list of publications for many years and can be found at: http://www.beg.utexas.edu/mainweb/publications/pubs-bstsell.htm In October 2002, the United States Geological Survey (USGS), in cooperation with the Texas Water Development Board (TWDB), began development of an Environmental Systems Research Institute (ESRI) geodatabase model to capture the power of these data. Phase I (2002-2004) of this effort produced a library of 38 ESRI personal geodatabases representing the original 38 BEG map sheets. Phase II (2005-2006) involved the development of a Statewide Digital Geologic Atlas of Texas, combining the 38 personal geodatabases into one ESRI ArcSDE geodatabase containing more than 145,000 geologic features. Phase III (2007), continued to build on the work completed in the previous two phases with the inclusion of higher-resolution geologic data from the USGS STATEMAP program and on-going geodatabase refinement. The final product is an ESRI personal geodatabase consisting of four feature datasets, corresponding to the four different resolutions of geologic data. Each feature dataset includes two feature classes: rock units and faults. Where available, other geologic feature classes may be included inside the scale-appropriate feature datasets (i.e. member units, geologic contacts, volcanic vents, etc.).

This dataset was derived using a variety of software tools in tandem. These included MS Access (Microsoft Corp.), Illustrator 10.0 (Adobe Systems Inc.), and ArcGIS 9.2 (ESRI Inc.) ESRI ArcCatalog 9.2.2.1350 Personal GeoDatabase Feature Class The following methods were used to test attribute accuracy of the input datasets used to construct these surfaces: 1) Manual comparison of the source with hardcopy plots. 2) Symbolized display of the working feature datasets on an interactive computer graphic system. 3) Selected attributes that could not be visually verified on harcopy plots or on the interactive computer graphic system were interactively queried and visually verified on a monitor screen. Polygon, polyline, and point feature attribute values (where applicable) were inspected and found to be consistently coded as described in the Entity and Attribute Information. This electronic report was subjected to the same review standard that applies to all USGS reports. Reviewers were asked to check the topological consistency, attribute accuracy, tolerances, projection, and geographic extent. Reviewers were provided digital datasets and paper plots for checking against the source maps to verify the linework and attributes. The reviewer examined both input data and output data for errors. Each one of the figures used for input data was scanned and registered independently. All data were projected to each sheet specific Transverse Mercator Projection. As part of the statewide compilation, the 38 map sheets were then reprojected to Albers Equal Area Projection. Refer to publications for contour interval of figures and origin of source materials. Scribe Processing The surface geology scribe sheet was obtained from the University of Texas Bureau of Geology and photo-scanned by a professional service at a 1:250,000 scale to make contact prints on stable contact paper. The contact prints were then georectified with an RMS of 0.003 or less, unless stated otherwise. The georeferenced .tiff was printed and overlain on the original contact print to check accuracy. Color Processing The published hardcopy University of Texas Bureau of Economic Geology Geologic Atlas of Texas map sheet was scanned and rectified with an RMS of 0.005 or less to create a color version used as an attribute guide during the editing and review processes. Creation of Linework ArcToolbox Using ArcToolbox, the georectified .tiff was converted into an ESRI grid dataset using the Image to Grid conversion tool. The grid was then converted into a vector data set using the Grid to Line Coverage conversion tool. The line coverage was printed and overlain on contact print to check accuracy. Editing Linework Linework was imported into a temporary geodatabase where the line topology rules "must not overlap", "must not have dangles", and "must not self overlap" were applied. Nodes were snapped and linework was corrected interactively using the georeferenced scanned scribe sheet as a guide. Linework for Fault, MemberPoly, MemberLine, and RockUnit were separated from each other and stored in their respective feature classes. Attributing Fault Directionality was assigned to node order to distinguish upthrown and downthrown sides. Faults were attributed with fault code in the fault domain. Fault domains are as follows: Unspecified fault = 1, Normal fault = 2, Inferred Normal fault = 3, Concealed Normal fault = 4, Thrust fault = 5, Transverse fault (From-To) = 6, Transverse fault (To-From) = 7, Anticline = 8, Syncline = 9, Overturned Anticline = 10, Overturned Syncline = 11. Domains can be matched with an ESRI symbology style file, GAT_fault.style, where arrows show downthrown side for normal faults, the overthrown plate for thrust faults, and directionality for transverse faults. Concealed and inferred normal faults are symbolized by dotted and dashed lines respectively. Attributing MemberPoly A polygon feature class was built in the geodatabase from the edited linework. Member polygons were attributed with the geologic member abbreviation associated with each individual Geologic Atlas of Texas mapsheet. Each polygon was also attributed with the name of the Geologic Atlas of Texas mapsheet on which the polygon centroid was located. MemberPoly features can be symbolized by using the provided ESRI symbology style file, GAT_member.style. In addtion, CMYK values have been included in the RockUnit attribute table for additional assistance with symbolizing these data. Symbology pattern codes can be cross-referenced through the Browse Graphic (Pattern_LUT.bmp) embedded in this metadata. Attributing MemberLine A polyline feature class was built in the geodatabase from the edited linework. Member polylines were attributed with the geologic member abbreviation associated with each individual Geologic Atlas of Texas mapsheet. In addition, each line segment was attributed with the name of the Geologic Atlas of Texas mapsheet on which the line segment centriod was located. Attributing RockUnit A polygon feature class was built in the geodatabase from the edited linework. RockUnit polygons were attributed with the geologic rockunit abbreviation associated with each individual Geologic Atlas of Texas mapsheet. Each polygon was also attributed with the name of the Geologic Atlas of Texas mapsheet on which the polygon centroid was located. RockUnit features can be symbolized by using the provided ESRI symbology style file, GAT_rockunit.style. In addtion, CMYK values have been included in the RockUnit attribute table for additional assistance with symbolizing these data. Symbology pattern codes can be cross-referenced through the Browse Graphic (Pattern_LUT.bmp) embedded in this metadata. Combining 38 Geologic Atlas of Texas geodatabases All 38 of the individual Geologic Atlas of Texas geodatabases were combined into one ArcSDE database for editing and review of the Statewide Digital Geologic Atlas of Texas. All of the geodatabases were loaded into a new feature dataset with an Albers Equal Area projection. Edgematching Each of the map sheet seams were visually scanned on computer monitor and discrepancies between sheets were noted using ESRI's Production Line Tool Set (PLTS), Data Reviewer. Using ArcMap Editor,Topology Editor and the Spatial Adjustment functions each of the 38 geodatabases were edgematched in areas which had no geologic disagreement between adjacent mapsheets. Polygon and Polyline features which did not agree on adjacent map sheets were noted in the PLTS database and sent to the geologic reviewer for further comment and suggestion for correction. All comments and suggestions have been collected and provided in the geodatabase, PLTS_Review. Upon the recommendation of the reviewer, all suggestions were then applied to the Statewide Digital Geologic Atlas of Texas through the use of ArcMap editing functions.
