As an efficient way to stimulate the growth of economy, tourism is promoted by most counties allover the world, and has
become one of the world's largest and fastest-growing industries. Essentially, tourism is a spatiotemporal system, with
tourist attractions located in different geographic areas and tourist flows exchanging between different geographic
regions. In this paper, we present a dynamic model for the simulation of tourism and tourist's activities in the context of
GIS and stochastic method, using a case of the Beijing-Tianjin-Hebei region. The model is developed on stochastic
method and multiple geospatial data sources. In the model, the spatiotemporal behavior of tourist on the Earth's Surface
is governed by the evolution rules, which are extracted from the researches on tourist's activities and executed via
stochastic method and multiple geospatial data. By means of the model, we simulate the tourism in the Beijing-Tianjin-
Hebei region, and find that there is good correspondence between the tourist arrivals calculated with the model and those
obtained from the tourism statistics. This shows that the animated dynamic modeling of tourism based on geospatial data
can be used as an indicator of the tourism in the realistic world, and is also can be embedded in the GIS applications.
