Alaska Geologic Data Index (AGDI)

Crafford, T.C. Crafford, Elizabeth others 2012 Alaska Geologic Data Index (AGDI) GeoTIFF Digital Data Series DDS 1 Fairbanks, Alaska, United States Alaska Division of Geological & Geophysical Surveys https://doi.org/10.14509/24504 http://doi.org/10.14509/agdi The Alaska Geologic Data Index (AGDI) is an actively growing index of unpublished geologic data collected throughout the state of Alaska. The records captured range from project documents to imagery to geochemical data. The index is designed to contain data and documents pertaining to all related fields of geology, including oil and gas, geologic engineering, minerals industry, scientific data, and agency archives. The index can refer to paper or digital information. Agencies, institutions, and the public are encouraged to contribute unpublished data to this dataset. Data owners can pick from three levels of data availability. These include: public - the data records in AGDI are visible to the public, and the archived documents are also available to the public; limited - the data records in AGDI are visible to the public, but the archived documents may not be available or are available at the discretion of the data owner; and private - records are visible only to the owner of the records and AGDI database administrator, and the archived documents may not be available or are available at the discretion of the data owner. If you would like to contribute data to this index, please contact the Alaska Division of Geological & Geophysical Surveys (DGGS) at dnr.dggs.webapps@alaska.gov. AGDI includes information about industry reports and maps, field notes, drill logs, and other data from the private sector. The data are available through a web service interactive web application with a text- and map-based search interface, data input and editing functionality, and data administration capability. The archived data are held and controlled by government agencies, institutions, and private companies; the index points to the physical location of the data, provides a basic description, and contains information on accessibility. The primary objective of the AGDI project is to ensure that all available Alaska minerals data are securely archived in perpetuity and in a format readily accessible by all potential users. Information on mineral resources is important for management policy decisions in both the public and private sectors. Increased use of high-quality data in all sub-disciplines of geology should lead to better economic, legislative, and environmental decisions.

The online AGDI dataset and application were compiled and developed through funding from the federal Minerals Data and Information Rescue in Alaska (MDIRA) program and State of Alaska's General Fund. The following DGGS employees helped create the ADGI application: Jennifer Athey (project manager, geologist), Susan Seitz (database manager/programmer), Simone Montayne (geologist), Ken Woods (systems administrator) and other programming staff. This material is based upon further work in 2021 supported by the U.S. Geological Survey under Grant No. G20AP00103 and the State of Alaska General Fund. The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the opinions or policies of the U.S. Geological Survey. Mention of trade names or commercial products does not constitute their endorsement by the U.S. Geological Survey. The dataset is stored in a PostgreSQL v.12.8 database. AGDI records are entered by the owners of the dataset and may vary in accuracy. Data may be unknown or poorly known. Referential integrity among the tables is enforced by the database system. AGDI contains a small subset of the unpublished geologic information of Alaska. We encourage agencies, institutions, and private entities to populate and use the database. Horizontal accuracy varies widely for each record. Location may be assigned by place name, quadrangle, area, or point. An "Estimated Location Accuracy" is requested (when known) for records located by area or point. Anaconda Minerals Co. Unpublished material Unpublished Anaconda Alaska collection electronic database unknown date of information Anaconda collection Dataset is contained within AGDI database. Crafford, Tom 2003 Minerals Data Information Rescue in Alaska (MDIRA): Anaconda Collection and More document 2003 Annual Convention, Anchorage, Alaska, November 3-8, 2003 Alaska Miners Association p. 24 paper 2003 publication date Crafford, 2003 Provided information on the indexing of initial data in the AGDI database. As part of the original BLM-funded MDIRA project, the Anaconda collection and approximately 2500 records of privately held minerals information were indexed into the Alaska Mineral Industry Data Index (AKMIDI) database. The collection includes about 10,500 records of more than 10 years of minerals exploration data collected throughout Alaska by the Anaconda Minerals Company and data from various other mining companies (Crafford, 2003). In total, the AKMIDI database contains 15,981 records from 20 different data sources. The data set includes geological, geochemical, and geophysical reports, surveys, field notes, maps, and images. The AKMIDI Access database was designed, indexed, and managed by T. Crafford & Associates professional geologists to ensure that the relevant information required by the minerals industry would be captured. The first set of records indexed was the Anaconda Collection, including digital photography of the maps and figures. This work was performed by Bristol Environmental and Engineering Corp. under contract to UAA. Anaconda Collection maps and files from outside of the Cook Inlet Region Incorporated (CIRI) region were donated to the University of Alaska Anchorage (UAA). The UAA-ARLIS library houses the regular-sized files while DGGS's Geologic Materials Center in Eagle River houses the over-sized maps and illustrations. Under contract by BLM, T. Crafford & Associates continued the project to obtain data from other data sources, focusing on native corporations. Nineteen other groups either entered their own data into a slightly modified version of the database or data entry was performed by T. Crafford & Associates. The 20 databases were merged into one Master AKMIDI database and the final product was delivered to the BLM in 2003. 2003 In 2011, DGGS received additional MDIRA funds to create a new search interface for the AKMIDI web search engine, which was desupported in 2009. The AKMIDI data structure was rebuilt and refined, and the data were ported into DGGS's Oracle database. The new data structure and AGDI application was enhanced to include all sub-disciplines of geology. The application contains a text- and map-based search interface, data input and editing functionality, and data administration capability. The data will also be available as WFS and KML. 2012 In 2021, DGGS received funding from the USGS National Geological and Geophysical Data Preservation Program, grant number G20AP00103, and the State of Alaska General Fund for a database and application rewrite. The database schema was reduced from 30 tables to 7 tables, and the data was converted to a PostgreSQL version 12.8 database platform. The application was rewritten using the Go programming language with Elasticsearch indexing for search functionality and OpenLayers for web mapping. The database contained 17,709 datasets with 8,833 files as of September 27, 2021. 2021 Point GS_1984_Web_Mercator_Auxiliary_Sphere 0 0 0 0 coordinate pair 0.00000001 0.00000001 meters D_WGS_1984 WGS_1984 6378137.000000 298.257223563 Alaska Geologic Data Index (AGDI) The AGDI feature service, data dictionary, and user guide.
