Geospatial Information System for tracking and navigation of mobile objects

摘要

Geospatial Information System (GIS) is a tool for manipulating, integrating and displaying geographically referenced information. It is a powerful system with high accuracy that is being used as the main backbone for a variety of path planning and navigation technologies widely used in the industry today. Tracking, security management, fleet management and industrial robot navigation are some regular applications. This paper presents the development of a geospatial information system for path planning and navigation of mobile objects. The system involves a GIS implemented using Google maps to visualize the routes of mobile objects acquired from GPS receivers over a GPRS network. A spatial database built into the system records the geographic information for later referencing. In addition, the GIS module is developed to perform route assignments and display historical information saved in the data repository.
