This is a Point data set.
The map projection used is GS_1984_Web_Mercator_Auxiliary_Sphere.
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 0.00000001
Ordinates (y-coordinates) are specified to the nearest 0.00000001
Planar coordinates are specified in meters
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257223563.
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), Chris Ramey (programmer), Simone Montayne (geologist), and Ken Woods (systems administrator).
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 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. This project is funded through the federal Minerals Data and Information Rescue in Alaska (MDIRA) program. The primary objective of the MDIRA program 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.

AGDI records are entered by the owners of the dataset and may vary in accuracy. Data may be unknown or poorly known.
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.
AGDI contains a small subset of the unpublished geologic information of Alaska.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.
Referential integrity among the tables is enforced by the database system.
