Every year, hundreds of people go missing in the wilderness of Saudi Arabia. There is an immediate need to examine modern geographic techniques for finding these people. Geographical information systems (GIS), for example, play a crucial role in WiSAR, not only in mapping probability areas but also in applying further analysis and modeling methods to reduce time and effort and guide life-saving task forces in the right direction. In a hypothetical case study conducted in Saudi Arabia, this study compares two standard WiSAR models, ring and mobility. In these situations, both models can be used. However, the new approach in the mobility model drastically reduces the possible search areas, from 101,787 km2 in the ring model to 335.34 km of likely trails and unpaved roads, and gives exact directions to where a missing person may be.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
