  11. 1 Specification (or Modification) of Standards of Geological Data Formats Methodology and Procedures Standards of Geological Data (Draft, 2009-2010) Standards of Taiwan Stratigraphic names and usage (2009) Digital Codes for Stratigraphy and Standards of Geological Map Legends (Draft, 2009) Quality Control Standards for Geological Map Data (Draft, 2009-2010)

  12. Methodology and Procedures Modification of standards of basic geological data (2008 v., draft) Gaps between digital geological data and existing printed maps Elimination of the gaps through establishing consistent standards of data formats Standards and criteria for quality control of digital geological data

  13. Existing Printed Geological Maps • The same stratigraphic units are represented in different legends(texture pattern )on different area sheets • Contempary stratigraphic units are shown in different colors on different area sheets • Texture pattern representing a stratigraphic unit does not conform with lithology • The same stratigraphic unit has different names or codes on different area sheets • There is different spelling of English names for the same stratigraphic units Methodology and Procedures Problems in Geological Maps

  14. Area sheet Stratigraphy Area sheet Stratigraphy Area sheet Stratigraphy Problems in Printed Geological Maps BiSaTung Miliao Dayuan Linko Sand Dune Chungli Dayuan Hsinchu Taoyuan Chungli Formation Taoyuan Miliao TonShe Nanto Jinshuei Shale Methodology and Procedures

  15. Digital Geological Map • Inconsistent map formats and data between digital and existing printed geological maps • Classified coding of digital data is not based on a hierarchy of stratigraphic units • Textural patterns of stratigraphic units on digital maps do not conform with conventional ones • Formats of digital geological data need to be standardized Methodology and Procedures Problems in Geological Maps

  16. Current Standards of Digital Geological Data Fig.ZA2 Balewan Formation (Conglomerate) Shuelian Conglomerate (Member) Fig.C48 Shebachungci Formation Fig.Z002 Methodology and Procedures Legends of stratigraphic units do not conform with conventional ones for sedimentary rock type, e.g. the legend color of Shebachungci Formation is not conventional (yellowish is better than reddish), the code is not appropriate and there is not English abbreviation

  17. Solutions 1. Based on fundamental principles of geology 2. Based on USGS standards system used by system used by Methodology and Procedures

  18. Specification of Standards and Practice Fundamental principles and application of geology Rationale Stratigraphic legends Stratigraphic coding Design Practice of designing legends Practice of designing codes Practice Application Prsentation of Stratigraphic data design of stratigraphic database Methodology and Procedures

  19. Standard of geological map data Standard of basic geological data QA/QC Practice of Geological Map Flow chart of Geological Data Standard Top Transform and circulation Standard of stratigraphic name and usage refer Standard of digital stratigraphic codes and legends Position of Standards Down Amendment of geological data standard Methodology and Procedures

  20. Goals for Modification of Standards in 2009 • Modification of standards of the basic geological data (draft) assistance in modification • Standards of geological map data (draft) 1.
