The Digital Mapping, Charting and Geodesy Analysis Program (DMAP) of the Naval Research Laboratory has developed an object-oriented (OO) digital mapping database prototype, called the Geospatial Information Database (GIDB), capable of importing any of the National Imagery and Mapping Agency's Vector Product Format data and converting the data into an object format. The DMAP Team has also investigated existing OO technology that would allow the transfer and retrieval of data from the GIDB over the internet. This article describes how we have used a Java applet and the CORBA standard to succeed in our endeavor to make mapping data from our GIDB accessible over the World Wide Web.
