7th EC-GI & GIS Workshop, 14-June-2001, Potsdam, Germany 2
VISPA Objectives
Developing a Mobile Digital Tour Guide for mountaineers, providing: Guidance
Orientation
Geo-Information
Combination of position- and geoinformation-data
Demonstration of feasability of such a service using GPRS for internet communication.

Core Services
Navigation Service:
• Providing localized Geo-Information (2D-, 3D rendered-map) on PINA-Server
• On-Line Tour Routing on PINA-Server or TourGuide
• On-Line Tour Guidance on User ‘TourGuide’ Mobile Device
General Information Service:
• Providing additional personalized thematic data (Tourist data) on PINA-Server
Extended functionality option:
• E.g. routing with constraints, emergency call, personalized tracking, group tracking, weather forecast, general internet

Displayed User Information
• 3D-Terrain visualization of the terrain in the line of sight to the proposed path as static picture
• Proposed path as line signature is visible in the terrain from his point of view
• Distance to the destination and to the next waypoint
• Direction to the destination and to the next waypoint
• Indication of Mobile Device orientation derivation with arrows (Cross-Track Error)
• Etc.

First Results / Experiences
Examples: 2D-map 3D-image view, rendered
from DTM data
Communication between PDA and hardware components (GPS RCVR, compass, mobile phone) difficult due to interfacing issues (H/W and S/W level). Now, most problems solved.
Currently, low transfer rates on GPRS data link, but increase expected.

Conclusions / Perspectives
The VISPA-concept gives the mountain climber/walker a deep confidence in the activities he is actually performing.
This ensures that he will pay for the service, but also should create additional tourist attraction for this sport having such an innovative system at hand.
Safety-of-Life:
• The core services are the essential part to prevent the outdoor activists from critical situations.
• The service emergency call extension enables fast notification in case of an accident. The personal tracking extension enables the SAR authority to assess the overall situation (how many people need help etc.) and to reduce reaction time ( PARAMOUNT project).
• Generally, the safety-of-life risk will be reduced.
TourGuide hardware more compact: e.g. Siemens SX 45 Multimobile
