IMPROVING ACCESS TO GEOSCIENCE INFORMATION -- THE REDESIGNED NATIONAL GEOLOGIC MAP DATABASE
In late 2012, a major redesign of the NGMDB was released, which focused on upgrades to the Map Catalog; the second phase of the redesign is now addressing updates to the U.S. Geologic Names Lexicon (Geolex) and the various NGMDB informational pages (e.g., standards development). The newest features at the redesigned site are: (1) “MapView”, which provides a mosaicked view of geologic maps , as a new front-end to the NGMDB's Map Catalog, and (2) topoView, which enables users to quickly search and browse the USGS Historical Topographic Map Collection. Also, the 94,600 "Product Description Pages" now include an improved map image viewer and a suite of image formats for download. This presentation will overview the redesigned site, and provide insight on the technical and other challenges faced during this database and Web site redesign.
