Geographic and geological datasets including remotely sensed imagery are increasingly being incorporated in many geotourism projects. These spatial datasets support all key stages of geotourism projects including initial research, planning, management, monitoring design and implementation of the project. In this chapter, we describe selected applications supporting the needs and the activities of planners, managers, scientists through to visitors, using examples from recent projects on the applications of geographic information systems and science (GIS) in geotourism. Spatial data analysis tools and primary data acquisition methods offered by remote sensing are invaluable in mapping and assessing landscapes and its components. A range of tools, applications and datasets are available for planners, managers and users of tourism destinations. Some of the applications include route planning, risk assessment, event planning, site assessment, monitoring.
