GIS and Information Management - GGGSC
Completed
By Geology, Geophysics, and Geochemistry Science Center
September 30, 2024
We support the geospatial component of Mineral Resources Program research and provide public access to research results and geospatial information. We facilitate all aspects of the data life cycle, including the publication and archiving of geospatial information and products. We also develop and steward national-scale data layers considered foundational to the Mineral Resources Program as well as implement geospatial technology to streamline or enhance research workflows.
What Our Project Does
The GIS Project provides GIS support to Mineral Resources Program (MRP) and other USGS projects. The project plays a pivotal role in the development, stewardship, and publication of local to national-scale data layers to meet the Federal mandate to provide geoscientific information to State and Federal agencies, private industry, and the public. GIS encompasses acquisition, compilation, processing, analyzing, modeling, visualizing, documenting, reviewing, publishing, and archiving of geospatial information products. The project conducts research using advanced geospatial technology and analyses to streamline workflows and to create innovative, multi-scale map products to support MRP's role in 21st Century science.
Tasks
GIS Support: provide ad hoc GIS and information management support to Geology, Geophysics, and Geochemistry Science Center (GGGSC) projects and to conduct specialized GIS tasks that are not directly related to other program projects.
GIS Operations: provide and maintain shared GIS, mapping, modeling, digitizing, and scanning resources for GGGSC projects and to supply users with operations support for these common-use systems.
Research and Development: develop and maintain geospatial data supporting MRP research and operational activities. In addition, this task will research and develop GIS methodologies for applying GIS, scientific visualization, data integration, modeling and data dissemination technologies as required. Participation on National Science Foundation project, "Collaborative Research: Brittle-plastic deformation, fluid-rock interaction, and extensional reactivation along Laramide thrust faults in the Sangre de Cristo Mountains, Colorado," includes legacy data compilation and analysis, as well as Sangre de Cristo spatial data for the Deadman fault zone and associated mineralization.

The Central African Copperbelt (CACB) is one of the most important copper-producing regions of the world. The majority of copper produced in Africa comes from this region defined by the Neoproterozoic Katanga sedimentary basin of the southern Democratic Republic of the Congo (DRC) and northern Zambia. Copper in the CACB is mined from sediment-hosted stratabound copper deposits associated...

Hydrothermally altered bedrock in the Silverton mining area, southwest Colorado, USA, contains sulfide minerals that weather to produce acidic and metal-rich leachate that is toxic to aquatic life. This study utilized a geographic information system (GIS) and statistical approach to identify watershed-scale geologic variables in the Silverton area that influence water quality. GIS...

Descriptive models, grade-tonnage relations, and databases for the assessment of sediment-hosted copper deposits: with emphasis on deposits in the Central Africa Copperbelt, Democratic Republic of the Congo and Zambia: Chapter J in Global mineral resou Descriptive models, grade-tonnage relations, and databases for the assessment of sediment-hosted copper deposits: with emphasis on deposits in the Central Africa Copperbelt, Democratic Republic of the Congo and Zambia: Chapter J in Global mineral resou
The Central African Copperbelt (CACB) is one of the most important copper-producing regions of the world. The majority of copper produced in Africa comes from this region defined by the Neoproterozoic Katanga sedimentary basin of the southern Democratic Republic of the Congo (DRC) and northern Zambia. Copper in the CACB is mined from sediment-hosted stratabound copper deposits associated...

Hyperspectral surface materials map of quadrangle 3562, Khawja-Jir (403) and Murghab (404) quadrangles, Afghanistan, showing iron-bearing minerals and other materials Hyperspectral surface materials map of quadrangle 3562, Khawja-Jir (403) and Murghab (404) quadrangles, Afghanistan, showing iron-bearing minerals and other materials
This map shows the spatial distribution of selected iron-bearing minerals and other materials derived from analysis of airborne HyMap™ imaging spectrometer (hyperspectral) data of Afghanistan collected in late 2007. This map is one in a series of U.S. Geological Survey/Afghanistan Geological Survey quadrangle maps covering Afghanistan. Flown at an altitude of 50,000 feet (15,240 meters...
