As part of a collaboration with the Federal Ordnance Disposal Coordination Center, a method was developed to identify risk zones for unexploded bombs based on the observed locations of bomb craters from exploded bombs. For example, it can be applied to study areas where information on the coordinates of exploded bombs is available from World War II aerial photographs. This method is based on techniques from spatial statistics and the theory of spatial point processes. The methodology has been implemented in the R package highriskzone. In addition, scripts were created that integrate the functionality of the R package into the geographic information system QGIS, thus enabling interactive analysis of the relevant data and embedding the methodology into existing workflows.
