----------------------------Original message---------------------------- NOTE regarding the release of "Cartographic and Digital Standard for Geologic Map Information," U.S. Geological Survey Open-File Report 95-525 The U.S. Geological Survey has released the report "Cartographic and Digital Standard for Geologic Map Information," as U.S. Geological Survey Open-File Report 95-525. The report establishes the standard for information presented on geologic maps and derivative earth science maps. The standard contains 3 parts: Part 1 presents the standard for the content of geologic maps, accuracy of position of geologic data, representation of data, and reference to original and derivative data. Part 2 establishes the standard for graphic and digital representation of geologic map data, including symbols, their cartographic specifications, and digital coding. Nearly 900 symbols are provided, and the text provides guidance for the definition of symbols not shown in the standard. Part 3 describes the standard for color and pattern selection and for graphic representation of rock types. Colored symbols, colors, and patterns are accurately provided in the report. The Standard results from work by the U.S. Geological Survey with cooperation from the Association of American State Geologists and the Federal Geographic Data Committee, Geological Data Subcommittee. As presented, the Standard is a draft standard, intended for use, review, and comment for two years by earth scientists across the Nation. At the end of that time, recommendations for changes and additions will be considered for possible inclusion in the final standard.
