This paper presents the research for the development of a new travel aid to increase the independent mobility of blind and elderly travellers. This aid will build on the technologies of geographical information systems (GIS) and the Global Positioning System (GPS). The MOBIC Travel Aid (MOTA) consists of two interrelated components: the MOBIC Pre-journey System (MOPS) to assist users in planning journeys and the MOBIC Outdoor System (MOODS) to execute these plans by providing users with orientation and navigation assistance during journeys. The MOBIC travel aid is complementary to primary mobility aids such as the long cane or guide dog. Results of a study of user requirements are presented and their implications for the initial design of the system are discussed.

Accurate and precise reporting of forest survey locations is required to integrate forest survey data with Geographical Information Systems. The accuracies of five Global Positioning System (GPS) survey methods using a hand-held receiver were tested in a mixed forest of trembling aspen and spruce. Accuracy improved by eliminating positions obtained under poor satellite configurations and by using position averaging methods. Single fix positions, taking as little as two minutes to obtain, yielded better than 100m accuracy more than 80% of the time. Allowing the receiver to continuously collect fixes for 15 to 30 minutes and then averaging the fixes yielded a median position error of 17 m. Sixty one stands representing a diversity of cover types, canopy heights, and crown closure in the Petawawa Research Forest were tested during June and July of 1992 for canopy interference with GPS signals. A GPS position was obtained under the canopy in 74% of the stands. Launches of additional GPS satellites since the summer of 1992 have further improved the probability of obtaining accurate geographical positions under forest canopies. Key words: global positioning system, position accuracy, signal reception, canopy interference

Technical development of Global Positioning System (GPS) is the positional determination system of ground control point in the earth surface, which based on satellite. It leads to the significant influence on the methodological aspect of positional determination survey in the earth surface. Global Positioning System gives the three dimension position (X, K Z) or longitudinal, latitude and altitude which are formulated in the reference of World Geodetic System (WGS) in 1984. The data characteristic is the first data, which is required in the survey of limit mapping of historical and archeological site. This article tries to explain the possibility of using the technology of Global Positioning System (GPS) to map the archeological site which contains of potential, ohstacle, methodology and case study in Boko Prambanan temple area. It is also utilized to the possibility of using the Geographical Information System (GIS) to analyze the spatial existence site of environmental condition.

This paper presents research and development work on a novel system with a view of developing a navigation system for the guidance of visually impaired pedestrians. The prime aim of the new developed system is to enhance the mobility of visually impaired pedestrians using remote guidance provided by sighted person. However, the system can be used in many other applications. The system implementation is based on the integration of the Global Positioning System (GPS), Geographical Information System (GIS) database and a remote vision facility over the third generation (3G) of mobile networks, providing a technological platform enabling visually impaired pedestrians to be guided remotely by a sighted guide.
