DETERMINING AND PRESENTING MOUNTAIN TRAILS QUANTITATIVE DATA
Abstract
Tourist trails are of great importance for mountain tourism and in recent years their situation came to the fore again in Romania too. Is typical of today’s tourists that they want to know more and more data regarding their destination, they want to visualize in a virtual world their selected places. Theref ore, a self-made analysis software were designed with the aim to determine the foll owing parameters: tota l length, rising and descending length over a given limit, mi nimum and maximum height, maximum elevation difference, hiking time, amount of burned calories. The input data for the software are data pairs which marks th e relative position along the route and their elevation values. Of course the main problem is the accuracy of those data which varies based on the used data acquisition sy stems and methods (GPS measurements, topographic maps, SRTM). Our research presents a short comparison of available basic data acquisition methods. The developed system offers the possibility to determine the hiking time and burned calories based on individual parameterization taking account the Tranter’s correction table and the person’s weig ht. The next step in our research was to recode in KML files the resulted data and presenting it in a Google Earth based website, offering the possibility for everyone to access it. In this phase the main problem that appeared and we have to overcome was that the Google Earth drape image for our main study region – the Easter Carpathians – has a 5-30m shift, which we demonstrated, based the Romanian National Geodetic Datum Grid.
