GI_Forum publishes high quality original research across the transdisciplinary field of Geographic Information Science (GIScience). The journal provides a platform for dialogue among GI-Scientists and educators, technologists and critical thinkers in an ongoing effort to advance the field and ultimately contribute to the creation of an informed GISociety. Submissions concentrate on innovation in education, science, methodology and technologies in the spatial domain and their role towards a more just, ethical and sustainable science and society. GI_Forum implements the policy of open access publication after a double-blind peer review process through a highly international team of seasoned scientists for quality assurance. Special emphasis is put on actively supporting young scientists through formative reviews of their submissions. Only English language contributions are published.

Abstract:
The Harz National Park (NP) offers a well-developed path network with a total length of 813 km, as well as a high number of starting and destination points for hikes. It was visited by about 1.7 million visitors in 2014. Due to its large extent, an accurate measurement of visitor numbers and their spatio-temporal distribution is not feasible. This paper demonstrates the possibility of simulating visitor streams around Mt. Brocken buy using the agent-based model (ABM) methodology. The GAMA v1.7 RC2 modelling environment was chosen, be-cause it has very extensive spatial operators and simulation tasks, combined with an easy-to-understand modelling language. To reduce the simulation effort, a model reduction factor MRF = 10 was tested successfully: no significant change to the model was required. After an initial parameterization, a sensitivity analysis was conducted, with the results in-cluded in the final calibration. The observed error value was significantly reduced, from RMSEparam=0,3817 to RMSEcalib=0,1069, and therefore the model was applied to the study area. For the final validation, visitor numbers from other, independent investigations were used. In addition to the 12 main routes and 7 hotspots identified, basic socio-economic indicators emerged. Hikers’ changes in behaviour according to framework conditions were analysed, demonstrating the impact of current measures on the reduction of path use. The final result is a flexible and expandable baseline model, which provides a realistic picture of the spatial distribution of hikers in the study area and additional key so-cio-economic figures.

Keywords:  agent-based model, Harz National Park, socio-economic monitoring, streams of visitors, groups of hikers
