Abstract

Accessing the National Geologic Map Database via ArcGIS Image Server
Track: Mining and Geosciences
Authors: Christopher Garrity

The AASG-USGS National Geologic Map Database, through its Geoscience Map Catalog, provides access to 89,000 maps and reports by 630 publishers. More than 23,000 of these publications are geologic maps.
The ArcGIS Server Image Extension by ESRI is used to display all of the available geologic maps in a web mapping environment, with a query function to identify the map and link to the catalog record. The extension is used to provide access to geologic maps for: (1) users of ArcGIS, who can directly link to our Web Service; and (2) the general public, who will gain access via a map viewer in the NGMDB Map Catalog web pages. This summer, production work begins on this initiative, refining the workflow, georeferencing maps, managing the map images within the Catalog's Oracle database, and preparing the website for public access to the REST service.
