Research paper : Creation of seamless geological map of Japan at the scale of 1:200,000 and its distribution through the web (K. Wakita et al.)−82 Synthesiology - English edition Vol.1 No.2 (2008) Term 1.Term 2.Term 3.Term 4.Term 5.Term 6.Term 7.Geosynclinal Model: An ancient geological model for hypothetical huge sedimentary basin. This was a major model for the origin of mountain building from late 1800s to 1960s. Accretionary Complex Model: A recent geological model for the origin of orogenic belts. The basic components of orogenic belts were derived from accretionary complexes that were caused by the interaction between subducting oceanic plate and continental margin. According to this model, the rocks that compose the foundation of Japan are composed of accretionary complexes.Submarine sliding origin: Major theory in the 1980s where submarine sliding caused fragmentation and mixing to form mélanges.Diapiric origin: A hypothesis to explain the ocean bottom around the Barbados Islands in Middle America, where extraordinary high pore fluid pressure caused mud diapirism to form mélanges.Tectonic origin: Theory that states tectonic shearing between subducting oceanic plate and overlying plate of the continental margin caused fragmentation and mixing to form mélanges.Geographic Information System (GIS): Any system for capturing, storing, analyzing, managing, and presenting data and associated attributes which are spatially referenced to earth. In narrow sense, it is an information system capable of integrating, storing, editing, analyzing, sharing, and displaying geographically referenced information. Vector format: Object-oriented data format that expresses spatial information consisting of polygon, line, and points. Spatial information is defined by location and attributes information.public, it is necessary to present finer geoinformation at larger scale. We started making seamless geological maps at scales of 1:50,000 to be utilized mainly in engineering and construction, and 1:25,000 to be used mainly for industrial and residential location survey. We ultimately aim to provide flexible services to general users by making these detailed contents accessible from cell phone or car navigation system. We shall continue to promote information and technology for safer society through our researches - creation of seamless geological maps and its interoperational technology - as Full Research of geoinformation. AcknowledgementWe would like to thank the members of the Geological Mapping Group, as well as Mr. Jun-ichi Miyazaki and Dr. Joel C. Bandibas of the Geological Survey of Japan, AIST for their kind cooperation to our research.TerminologyTerm 8.Term 9.Term 10.Term 11.Term 12.Affine transformation: A transformation method using linear transformation and parallel movements (eg. Euclidean geometry). Relationship between geometric lines is preserved after the transformation process.Geochemical map: Map showing distribution of 53 chemical elements based on the chemical analysis of about 3,000 samples from 10 km grids covering entire Japan.Geography Markup Language (GML): A standard for spatial and geographical data defined by the Open Geospatial Consortium based on XML.Web Feature Service (WFS) and Web Map Service (WMS): WFS is interface standard for geographical vector features, and WMS is spatially referenced information, defined by OGC.GEO Grid (Global Earth Observation Grid): A system to facilitate the integration of earth observation data and other spatial information using grid technology.References[1][2][3][4][5][6][7][8][9][10][11][12]S.
