  8. Title: Global GIS : Mineral Resource Data System (MRDS) data in ArcView Shape File Format, for Spacial Data Delivery Project, 1999

    Contributors:

    Summary: This datalayer is a point coverage representing metallic and non-metallic mineral resources worldwide. This data was derived from the Mineral Resource Data System (MRDS) data in ArcView Shape File Format, for Spatial Data Delivery Project, 1999 (Edition: Version 1.1) and was published as part of the USGS Global GIS : global coverage database (2003). MRDS contains variable-length records of metallic and nonmetallic mineral resources of the world. A record contains descriptive information about mineral deposits and mineral commodities. The types of information in the data base include deposit name, location, commodity, deposit description, geologic characteristics, production, reserves, potential resources, and references. The Mineral Resource Data System master database is not accessible via the WWW. The large number of multi-valued fields make it difficult to import all the fields into a data format that can be utilized by the ArcView Internet Map Server Software. This dataset contains all MRDS locations, but only 44 of the possible 226 fields. A data structure was created in Access 97. Data was imported into the file structure and then processed into Arc View, where it was transformed into shape files that are used by the IMS software to serve the MRDS data and permit access via the www. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.

  14. Title: Global GIS : Earthquake epicenters (1973-2003)

    Contributors:

    Summary: This datalayer is a point coverage representing earthquake epicenters (1973 through March, 2003). Historical data for this layer were derived from: USGS/NEIC, 1973- March 2003: (PDE) Preliminary Determinations of Epicenters, Monthly Listing. This list is the most complete computation of hypocenters and magnitudes done by the USGS NEIC. It is normally produced a few months after the events occur. The publication is called 'Preliminary' because the 'final' computation of hypocenters for the world is considered to be the Bulletin of the Internation Seismological Centre (ISC), which is produced about two years after the earthquakes occur. The NEIC PDE program contributes about one-third off all data used by the ISC.

  15. Title: Global GIS : World gazetteer (major cities)

    Contributors:

    Summary: This datalayer is a point coverage representing major cities worldwide based on information from the GNS (GEOnet Names Server). For global (non-U.S.) cities, the GNS data was supplemented by the ESRI Data & Maps (2000) World Cities layer. For United States cities, the GNS data was supplemented by data from the GNIS (Geographic Names Information System). This dataset was published as part of the USGS Global GIS : global coverage database (2003). The GEOnet Names Server provides access to the National Imagery and Mapping Agency's (NIMA) database of foreign geographic feature names. Approximately 20,000 of the database's 3.5 million features are updated monthly with names information approved by the U.S. Board on Geographic Names (US BGN). The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million.

  16. Title: Global GIS : Geologic map (excluding the United States)

    Contributors:

    Summary: This datalayer is a polygon coverage showing U.S. Geological Survey defined geologic provinces of the World, excluding the United States. It was published as part of the USGS Global GIS : global coverage database (2003). The World Energy Assessment created geologic maps of 7 regions. These regions were joined with minimum edge matching or checking for feature description by the Global GIS team. The user is warned there will be discrepancies on bordering features. The regions are described in the Geologic Provinces of the World full metadata files. Canada, Mexico and Central America, and the Europe tiles were screen digitized by the Global GIS team. These were approximately located and should be used as a geologic guide. The US and Alaskan Geologic Maps were kept as separate layers to allow the use the apply their original legends. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.

  17. Title: Global GIS : volcanoes of the world ; volcano basic data

    Contributors:

    Summary: This datalayer is point coverage containing basic geographic and geologic information for worldwide volcanoes thought to have been active in the last 10,000 years (Holocene). The data is a collection of information by Smithsonian Institution volcanologists summarizing 1,509 volcanoes and this version of the data set was published as part of the USGS Global GIS : global coverage database. The data was adapted from Simkin and Siebert, 1994 'Volcanoes of the World: an Illustrated Catalog of Holocene Volcanoes and their Eruptions' and produced digitally by the Smithsonian Institution's Global Volcanism Program. The data include a unique volcano number, volcano name, location, latitude and longitude, summit elevation, volcano type, status, and the time range of the last recorded eruption. More detailed descriptions of the data elements, plus more information on the volcanoes and their eruptions, can be found below and in 'Volcanoes of the World' (Simkin and Siebert, 1994). The book provides a discussion of the many cautions that are so easily stripped away from an electronic database, such as the incomplete and uneven nature of the historical record, even in this century, and the large uncertainties surrounding many older eruption dates. The accuracy of the record varies enormously from one region to another (and one century to another), and the sea-floor volcanism that dominates our planetary magma budget is scarcely represented in this data set. The basic building block of the Smithsonian's volcano database is the 'Catalog of Active Volcanoes of the World' (CAVW), a series of regional volcano catalogs published by IAVCEI beginning in 1951. The listings are not intended to be a comprehensive bibliography of references for a particular volcano or region, but represent those references that are cited as the sources of the volcano and eruption data in the CAVW. Several other global compilations have been helpful: among them are IAVCEI data sheets of post-Miocene volcanoes (1975-80), Volcano Letter reports of the U S Geological Survey from 1926-1955 (compiled in Fiske et al., 1987), independent compilations by Latter (1975) and Gushchenko (1979), and a caldera compilation by Newhall and Dzurisin (1988). Major sources of eruption data subsequent to or supplementing the CAVW can be found in a series of annual summaries by Gustav Hantke published between 1939 and 1962 (mostly in the IAVCEI publication Bulletin of Volcanology), and annual eruption compilations by the Volcanological Society of Japan (1960-96) and Smithsonian Institution reports (since 1968) in various formats, compiled in McClelland et al., (1985) and in the Activity Reports section of the Smithsonian Institution, Global Vulcanism website (Venzke et al., 2002-). The data sources referenced focus almost exclusively on Holocene volcanism and emphasize papers on volcanic stratigraphy and physical volcanology. Abstracts are typically not referenced unless they contain significant data not in other sources. As with the Georef bibliographic database, diacritical marks are not used.

  18. Title: Global GIS : United States gazetteer, populated places

    Contributors:

    Summary: This datalayer is point coverage gazetteer representing populated places in the United States and its territories. It contains official names and locations of populated places (PPL) as defined by the U.S. Board on Geographic Names. It is derived from the Geographic Names Information System (GNIS) and was published as part of the USGS Global GIS : global coverage database (2003). The Geographic Names Information System (GNIS), developed by the U.S. Geological Survey in cooperation with the U.S. Board on Geographic Names (BGN), contains information about physical and cultural geographic features in the United States and associated areas, both current and historical, but not including roads and highways. The database also contains geographic names in Antarctica. The database holds the Federally recognized name of each feature and defines the location of the feature by state, county, USGS topographic map, and geographic coordinates. Other feature attributes include names or spellings other than the official name, feature designations, feature class, historical and descriptive information, and for some categories of features the geometric boundaries. The database assigns a unique feature identifier, a random number, that is a key for accessing, integrating, or reconciling GNIS data with other data sets. The GNIS is our Nation's official repository of domestic geographic feature names information. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.
