Abstract

Access to the National Imagery and Mapping Agency´s (NIMA´s) Vector Product Format data is essential to the evolution of digital mapping products. Currently, users of NIMA data must have software to view the data resident on their own computer systems, and must obtain the data on CD-ROM or other storage media. This paper examines the design of an object-oriented (OO) digital mapping database prototype, called the Geospatial Information Database (GIDB). The GIDB provides accessibility to NIMA mapping data over the Internet in a CORBA-compliant manner. We describe a software solution to create a thin client product to enable viewing and manipulation of NIMA mapping data, and utilize n-tier concepts for data manipulation on the server side. We discuss difficulties encountered during the modeling and implementation stages of our development of the GIDB, as well as examine improvements made to increase the efficiency of our system
