A case study in the evaluation of geotourism potential through geographic information systems: application in a geology-rich island tourism hotspot

The significant growth in geotourism across all continents over the past two decades has created a strong demand for more creative, robust and systematic approaches to assessing the geotourism potential of natural areas, for identifying suitable sites of geological interest and providing comprehensive frameworks for management. We investigate a range of spatial data-sets using remote sensing analysis tools as well as geographic information systems (GIS) to complement field-derived data and allow for comprehensive analysis of combined data-sets. Such an approach allowed the creation of a spatial geological data base which can be assessed against access and management criteria, including environmental factors and risks. We used the relatively data-rich example of Rottnest Island in the south-west region of Western Australia to demonstrate the opportunities for future geotourism project development.
