Uncertainty in Mine Risk Visualization within Non-technical Survey

Landmines affect the lives of people living in war-affected countries. The real challenge in humanitarian demining nowadays, within Non-technical Survey, is finding new approaches to SHA reduction. The establishment and use of mine information systems in humanitarian demining can improve the land release process by efficient mapping of suspected hazardous areas and visualizing of mine risk on it. Croatian Mine Action Center established such system and uses it for marking all suspected hazardous areas in Croatia. Nevertheless, data in this system comes from different sources and contains some inherent uncertainty. The level of ambiguity is being attempted to diminish by conducting analytical assessments of mine information system data and by collecting additional information about suspected hazardous areas. The landmine risk mapping requires defining the input data (indicators) from mine information systems and additional data that most suitably capture the association between the spatial objects of interest in the surrounding geographic area. The confidence level for each indicator is determined, which is, in fact, an estimate of the level of uncertainty. The fusion of all existing data is used after that for the purposes of creating of mine danger maps. These maps show the overall uncertainty of all input data and need further action for their use in reduction according to the Croatian Mine Action Center Standard Operational Procedures.
