Abstract
This paper presents new system architecture, design, tests, performance analysis and effectiveness of using TELETEXT of the Television signal to grant GIS with Real-time general and specific-location Textual information capable of offering personalised services to endless number of users.
This concept integrates both data frames of GPS and TELETEXT then builds geographical coordinates as used in the World Geodetic System (WGS 84) for the TELETEXT frames. The new concept provides a continuously and automatically data matching of location data frames with an equivalent TELETEXT data frames related to specific or general locations Afterwards, map charts and WGS 84 grid are matched with all data frames then displayed in layers.
The testing and results obtained were sufficient to prove that the challenge of using TELETEXT and location data frames is sound and workable for providing low cost Real-time information for GIS users. The system has been tested on approximately 450 hours of data and results have demonstrated good performance.
