GPS-MAP: A Real-Time Graphical Database and Navigation System

Steven M. Honkus

Abstract:	A portable navigation and mapping system was designed incorporating a portable pen-based computer, an integrated OEM GPS receiver (Trimble Sveesix), and Mapping software to provide the user with navigation and data collection capabilities. The system , GPS-MAP can be used both in an urban setting where, with street level maps and an included geocoding feature, the user can locate and navigate to specified streets and addresses. The GPS-MAP system can also be used in a rural environment where a user can collect raw GPS data to create maps and log features from GPS data. GPS-MAP also incorporates a powerful relational database engine that allows the user access to existing database information through SQL queries with respect to the user’s current location and other existing map data. The GPS-MAP system allows the user to create points, polylines, and region objects from GPS data in real-time and can work in both stand-alone and differential modes. The system can be used to verity existing data in a Geographic Information System (GIS) gather new data, or add coordinate information to kxisting database information. This paper will describe the GPS-MAP system features and the use of the system on a recent project in Kazakhstan, where the system was used in support of a GPS vertical control survey. The paper will show how the system was used during several phases of the project from the initial reconnaissance of the area, the recovery of survey control, creating project maps of the area, and in ground-truthing satellite imagery. The paper will also discuss how the system was used in conjunction with the other GPS equipment used on the project which included Trimble 4000SE receivers, .and Magellan NavPro 5000 receivers. This paper will discuss how the system can be used productively with stand-alone GPS, DGPS, or both, and the benefits of having access to all of the GPS data in real-time as it is being collected.
