Frequently Asked Questions (FAQs)

What is the Alaska Geologic Data Index (AGDI)?

AGDI is a catalog of unpublished geologic data covering the state of Alaska. The application contains a text- and map-based search interface, data input and editing functionality, and data administration capability. The actual archived data is held by the data owners; the index points to the physical location of the data, provides a basic description, and contains information on accessibility.

User instructions for the search, data input, and data editing components are provided below. More information about the application and underlying data can be found in the metadata file.

What types of geologic data does AGDI contain?

The index is designed to contain data and documents pertaining to all geology-related fields, including oil and gas, geologic engineering, minerals industry, scientific data, and agency archives. The index can refer to paper or digital information.

Is AGDI based on the Alaska Mineral Industry Data Index (AKMIDI) database?

The Alaska Mineral Industry Data Index (AKMIDI) data are the seed data in the AGDI database, with nearly 16,000 records for mineral information owned by 18 diverse groups around the state, including Native corporations, private companies, state libraries, and land managers. The index includes information needed to find industry reports and maps, field notes, drill logs, and other data from the private sector. Much of the data is still held and controlled by private entities. Approximately 1,800 files and 4,300 maps from the Anaconda collection of minerals exploration data are available through the Alaska Resources Library and Information System (ARLIS) in Anchorage.

How can I contribute information to AGDI?

Contact DGGS at to obtain a username and password for the application. Maintaining the appropriate privacy of a username and password is the responsibility of the record owner.

Does AGDI contain proprietary information?

Data owners can pick from three levels of data availability. These include:

How can multiple people have access to records that are private or require editing?

A username and password may be designed to either be assigned to a specific individual or be shared among individuals. For example, a username and password may be shared within an organization so that more than one individual in the organization can edit the records and query records that are private. Maintaining the appropriate privacy of a username and password is the responsibility of the record owner.

Searching Records in AGDI

AGDI Search Philosophy

Geologic records may be queried by geographic area, specific text, or a combination of area and text. Because not all legacy data in the database are associated with a spatial object, separate geographic and text searches may be necessary to return all of the applicable information.

Geographic-based searches

An Area of Interest (AOI) search is available from the map interface. Click on the icon (active icon is yellow) and click and drag your mouse to define your area of interest. Geographic searches will often return spatial objects outside of the AOI selected, because a given record may be associated with multiple spatial objects, and all spatial objects for a record are displayed on the map.

Text-based searches: Basic Search Bar

The application is designed to provide results for broad and narrowly focused searches. The basic search bar above the map allows for robust queries of multiple single terms, phrases, term modifiers, and Boolean operators. The default behavior of the basic search bar is to select records on a "best match" basis. For example, a search for...

silver gold copper

...will return records that have all three terms in multiple fields at the top of the results list. Results are required to contain all three terms. Below is a table of additional ways to narrow queries in the basic search bar. These searching techniques may also be combined and grouped.

Search Example(s) Results
Term(s) silver gold Find records where both silver and gold are present
Phrase "silver gold" The Mineralogy and Geochemistry of the Kasaan Peninsula Iron-Copper-Silver-Gold Skarns, Prince of Wales Island, Southeastern Alaska
On specific fields @title gold
@title "gold creek"
Any title: with the word gold in it
Assay Plan, Gold Creek Tunnel
Proximity "silver gold"~10 Returns records with any field that contains silver and gold within 10 words of each other;
Commodities: silver, antimony, mercury, tungsten, gold
Strict order operator "<<" gold << copper Matches only if terms are exactly in the query order; Commodities: gold, silver, copper
Boolean AND operator silver AND gold Default operator between terms; finds records where the terms or phrases are found anywhere in the fields being searched
Boolean OR operator silver OR gold Returns records with either silver or gold, or both terms
NOT or "-" silver NOT gold
silver -gold
Both examples find records that contain silver but not gold

The basic search bar searches the following fields: "title", "", "authors.last", "authors.first", "description", "", "", "", "", "archived_by.last", "archived_by.first", "", "", "", "", "catalog_number", "date_reviewed", "date_archived", "year_begin", "year_end", "availability_remarks", "storage_remarks", "", and "owner". See Appendix A for definitions of the fields.

Text-based searches: Searching with "More Options"

The More Options button opens a side panel with additional fields to restrict searches. These parameters are more restrictive in the number of fields they query, and can help narrow down a search considerably. A search conducted on one or more fields from the More Options section or the basic search bar will only return records that match all of the parameters entered. For example, a search conducted on...

Basic search bar: gold
Keyword: silver
Year: 1971-1971

...will only return records from 1971 that contain both silver and gold. Below is a list of the fields involved in the More Options section parameters. See the Appendix A for a complete list of the fields and their definitions.

More Options Parameters Fields searched on
Keyword A single term or phrase within the Dataset Type, Theme, and Commodity fields.
Author First and (or) last name of the individual or name of the organization who collected the data, wrote the report, or created the collection.
Title Single-word or phrase search of title identifying the dataset or item.
Project Single-word or phrase search on the name of the project with which the dataset is associated.
Year(s) To search a single or range of years when the dataset or item was created or collected, the From and To fields must both be entered. A year enter in only the From field acts as Greater Than search; for example, "1980" entered into the From field will return records with a Year of "1980" or later. Conversely, "1980" entered into the To field will return records with a Year of "1980" or earlier.
Location A single term or phrase that searches within the Quadrangle, Place Names, Mining District, and Region (legacy) fields. Also accepts Boolean operators and term modifiers.
Data Source Search among individuals or organizations who provided the dataset or item. A search on multiple Data Sources will return all records with those Data Sources.
Dataset Type Search among the types of content the dataset could represent. A search on multiple Dataset Types will return all records with those dataset types. See Appendix B1 for the list and definitions of Dataset Types from which to choose.
Themes Search among a general list of keywords that describe the dataset or item. A search on multiple Themes will return all records with those themes. See Appendix B2 for the list of Themes from which to choose.
Commodities Search among a list of commodities associated with the dataset or item. A search on multiple Commodities will return all records with those commodities. See Appendix B3 for the list of Commodities from which to choose.

Appendix B1: Dataset Types

Delimited list and definitions ascribed to parameter Dataset Type.

Dataset Type Definition
Administrative Documents relating to planning, business operations, permitting, and legal agreements. Examples include agreements, legal documents, permits and permitting applications, feasibility reports, mine-level plans, survey information, prospectus reports, claim information and claim maps, and correspondence.
Analytical Lab Results Information derived from secondary processing of geologic samples. Examples include: Major-oxide, minor-oxide, and trace-element geochemical data; geochronology measurements and age determinations; porosity, permeability, and capillary pressure measurements; organic geochemistry data; palynology data; fossil descriptions and analyses; and point count data.
Bibliographic and Reference Materials Items or documents compiled for the purpose of summarizing and/or sharing known information about a given area, project, or methodology.
Dissertation or Thesis A formal presentation of original research generated to fulfill university graduation requirements.
Geologic Interpretations Interpreted surface and/or subsurface data. This category generally indicates that the information was collected or interpreted via human observation, and/or presents a geologic interpretation of data collected by some mechanical, remote sensing, or geophysical means. Examples include well and drill-hole logs, field notes, cross-sections, illustrations, geologic maps and descriptions, and stratigraphic observations.
Geophysics, Remote Sensing or Aerial Images Information captured by technologies that provide information about features that are undetectable to the human eye, occur below the earth's surface, and/or occur at a regional scale. In the case of legacy data this information would typically be presented in print; however, modern technologies may produce a wide range of file and media types. Methodology examples include gravity, magnetic, radiometric, electromagnetic, ground-penetrating radar, seismic, lidar, satellite data, and aerial photos.
Photo or Raster Image Images captured by a conventional handheld camera or laboratory imaging device. Examples include SEM images and outcrop and rock sample photos.
Poster, Presentation, or Abstract Items that provide a concise summary of project findings and are formatted for inclusion in conference proceedings or as a poster display.
Sample Locations Items that provide the geographic location, surface elevation, or subsurface depth of a geologic observation or sample.
Summary Report Completed work summarizing and/or presenting a synthesized compilation of project findings. This category should be considered analogous to "gray literature". Items that fall into this category typically would be cited as an unpublished report. Documents and/or maps belonging to this category may be identified by elements such as a formal title and title page, standardized cartography, bound pages, numbered pages and sheets, funding agency and author credits, organized content, a reference list, and/or an agency publication number. Examples include mineral exploration reports, engineering reports, technical reports, contracted final reports, and finalized maps.
