Authors: Christopher Garrity, David Soller, Mark Reidy

The AASG-USGS National Geologic Map Database, through its Geoscience Map Catalog, provides access to 86,000 maps and reports by 630 publishers. Access to these geologic maps and other types of geoscience reports is provided via the Catalog with links to sales offices, libraries, and web servers where the products can be downloaded.
ESRI's ArcGIS Server Image Extension is used to display available geologic maps through numerous image services, with a query function to identify the map and link to the Catalog. The extension is used to provide access to geologic maps for: (1) users of ArcGIS, who can directly consume image services; and (2) the general public, who will gain access via a map viewer in the NGMDB Map Catalog web pages. Work began on this initiative in the summer of 2010, georeferencing maps,and preparing the website for public access to the REST service via ArcGIS Server API for Flex.
