The Naval Research Laboratorys NRL Geospatial Information Database GIDB Portal System is a standards-based portal for geospatial information discovery, access and mapping over the Internet. The system has proven to be a powerful tool for gathering heterogeneous environmental data from disparate databases distributed across the Internet. Information is displayed in a GIS like fashion for data overlay and comparison using NRLs or other popular viewers Data can be exported in several formats for use in analysis packages. The technology is being used in the new Tactical Environmental Data Services TEDServices architecture. The portal system was developed in Java for platform portability. Its components include a downloadable thick client, a Web browser-based thin client, a PDA client and a flexible, plug-in server architecture implemented as a Java servlet that can allow data of any origin to be distributed to the clients. An open source, all Java object-oriented database management system, called Ozone, is also available for deployments requiring custom data storage. The GIDB Portal System presently connects the user to 128 servers including over 800 services across the U.S. The system is government-owned and requires no licensing. The GIDB Portal System is area-of-interest and theme-of-interest driven for ease of use from a neighborhood-level to country or world resolution. This Portal System technology has been under development at NRL for the past nine years with support from multiple sponsors including ONR, NRL, NIMA and SPAWAR. These efforts have culminated in an advanced portal system that is being used operationally by several programs. The U.S. National Guard Counter Drug Program is currently using a version of the GIDB Portal System technology as the basis for their Digital Mapping Server DMS Portal in support of counter drug agents and agencies.
