Searching and Exploitation of Distributed Geospatial Data Sources via the Naval Research Lab''s Geospatial Information Database (GIDB™) Portal System

摘要

The Naval Research Laboratory''s Geospatial Information Database (GIDB™) Portal System has been extended to now include an extensive geospatial search functionality. The GIDB Portal System interconnects over 600 distributed geospatial data sources via the Internet with a thick client, thin client and a PDA client. As the GIDB Portal System has rapidly grown over the last two years (adding hundreds of geospatial sources), the obvious requirement has arisen to more effectively mine the interconnected sources in near real-time. How the GIDB Search addresses this issue is the prime focus of this paper.
