|Since 2005, the Swiss National Park offers a mobile information system called WebParkSNP which provides content about the users surroundings using smart phone services and GPS. Up to now, little is known about the use of Location Based Services (LBS) by visitors of remote and protected areas and about the contents they are interested in. WebParkSNP logs time, location and content of each action the user conducts. Contents are not only pushed but can be accessed from every location. With the consent of 419 users, WebParkSNP’s log files of the summer season 2007 have been analysed in order to compare the user’s actions with the topography of the Park. Topography is composed of specific places (vegetation classes, aspect, and slope of the trail), facilities (resting areas, huts) and viewpoints. The results show that clustering of access occurs on steeper slopes, within facilities, and on viewpoints on certain routes. The content accessed differs between facilities and other places. Nevertheless, these patterns are not only determined by topography but also by behavioural aspects; the use of the guide depends on the daytime and on the distance from the starting point of the walk as well. These results allow the evaluation and improvement of LBS concerning content and locations. In addition, conclusions can be drawn about the development and improvement of other offers in the Park. Further analysis and the integration of other visitor surveys like census and questionnaires will show the potential for more general insights into visitor behaviour in protected areas.
