This online research tool provides the locations and outlines of most DGGS and U.S. Geological Survey (USGS) geologic maps of Alaska in a single, interactive web application. It allows searches of the map database by geographic area of interest, keywords, publishing agency, dates, and other criteria. The search results link DGGS's comprehensive, multi-agency publications database, where users can view and download publications for free. Map Index provides access to traditional geologic maps and sample location, geologic hazards, and geologic resources maps. In addition, DGGS plans to add outlines and data to the application for new and remaining geologic maps published by DGGS, USGS, U.S. Bureau of Mines, and U.S. Bureau of Land Management. Reports without maps can be accessed through DGGS's comprehensive publications database, . Purpose: The Map Index interactive web mapping application facilitates the discovery of geologic maps needed to perform research, make informed resource- and land-management decisions, and better understand the geology across Alaska. Supplemental_Information: DGGS appreciates the collaborative support from the U.S. Geological Survey's National Geologic Map Database project (David Soller, USGS Project Chief), which provided data for thousands of U.S. Geological Survey geology-related maps in Alaska.

Data_Set_Credit: The online Map Index 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, and continue to be supported by the State of Alaska General Fund. The redesigned 2021 web map application was funded by the USGS National Geological and Geophysical Data Preservation Program under award number G20AP00103 and the State of Alaska General Fund and implemented by Michael Hendricks (GIS analyst), Susan Seitz (database manager/programmer), Jennifer Athey (project manager, geologist), and Simone Montayne (geologist). The following DGGS employees helped create the 2013 Map Index application: Jennifer Athey (project manager, geologist), Susan Seitz (database manager/programmer), Anonymous (programmer), Simone Montayne (geologist), and Ken Woods (systems administrator). Application design ideas and an application prototype were provided by Will Fisher, Geographic Information Network of Alaska (programmer). DGGS staff responsible for original data compilation: Laurel Burns (project manager, geophysicist), Robin Smith (geologist), Shelley Hicks (geologist), and Heather Erickson (geologist). USGS collaborator David Soller (Chief, National Geologic Map Database project) provided data for Alaska's thousands of U.S. Geological Survey geology-related maps. Native_Data_Set_Environment: The dataset is stored in a PostgreSQL database and made available to the Map Index Web App through a GIS-enabled table. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Map Index records are checked programmatically to be consistent with other publication databases. Errors, inconsistencies, and missing records may be reported to . Logical_Consistency_Report: Referential integrity among the tables is enforced by the database system. Completeness_Report: On its launch, Map Index contained records for approximately 90 percent of DGGS's total geology-related map collection and approximately 70 percent of the USGS's map collection. The collection currently contains about 99 percent of DGGS' maps and 90 percent of Alaska USGS maps. DGGS plans to add outlines and data to the application for new and remaining geologic maps published by DGGS, USGS, U.S. Bureau of Mines, and U.S. Bureau of Land Management. The application will be updated irregularly with new map publications as they become available. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All maps have an associated spatial footprint, either as an outline surrounding the area that was mapped or as a rectangular outline representing the extent of geologic mapping. The map outlines are generalized and do not correspond exactly with the actual mapped area. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: U.S. Geologic Survey Publication_Date: unknown Title: National Geologic Map Database Type_of_Source_Media: electronic database Source_Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: unknown Source_Currentness_Reference: date of information Source_Citation_Abbreviation: USGS Staff, unknown Source_Contribution: Alaska maps were subset out of the NGMDB database and loaded into DGGS's publications database for the Map Index application. Alaska information can also be searched through the NGMDB Map Catalog, . Process_Step: Process_Description: DGGS and USGS publication and geospatial data were compiled from 2000-2005 by DGGS employees. In 2003, in cooperation with DNR's Land Records Information Section (now Information Resource Management), DGGS released the first version of the "Geologic Map Index of Alaska" web application. The beta-application was desupported in 2009 and decommissioned in 2011. Process_Date: 2011 Process_Step: Process_Description: In 2011, DGGS received additional MDIRA funds to create a new search interface for the Map Index web search engine. The new application was initially designed and built by programmer Will Fisher, UAF-Geographic Information Network of Alaska, and then later overhauled by DGGS programmers to better fit with DGGS's I.T. platform. Data from the 2000-2005 compilation was imported into DGGS's enterprise database and programmatically quality checked. Additional Alaska USGS publication and geospatial information were provided by the USGS National Geologic Map Database (unknown USGS), loaded into the DGGS enterprise database, and cross-checked with existing USGS publications. DGGS continues to update the Map Index application with additional legacy maps and new maps as they are published. Process_Date: 2013 Process_Step: Process_Description: In 2020, DGGS received funding from the USGS National Geological and Geophysical Data Preservation Program under award number G20AP00103 and the State of Alaska General Fund to redesign the Map Index online application. The Map Index data were migrated from an Oracle to PostgreSQL database platform. Map Index data are made available to the application through a feature service from a concatenated table in the PostgreSQL database. The custom web mapping application was redesigned using Esri ArcGIS Enterprise Portal version 10.8.1 and Web AppBuilder. DGGS continues to update the database with map publications as part of its regular publication process. USGS maps are updated irregularly.
