This paper presents a strategy for the analysis of landmine events, combining spatial data mining (SDM) and Geographic Information Systems (GIS) in an enriched data environment. This strategy allows to acquire useful information to improve the prevention, detection and response to the problems of planning humanitarian demining operations in Colombia. For this study, we analyzed the events in Colombia during the period 2006-2011, using GIS and tools for spatial analysis. Additionally, we present the techniques used and the results obtained by applying density tests, measures of central tendency, statistical significance, areas of influence, and hotspot interpolation methods.
