| Abstract: | Previous research on the RAG color‐coded prioritization systems for the discovery of clandestine graves has not considered all the factors influencing the burial site choice within a GIS project. The goal of this technical note was to discuss a GIS‐based quantitative approach for the search of clandestine graves. The method is based on cross‐referenced RAG maps with cumulative suitability factors to host a burial, leading to the editing of different search scenarios for ground searches showing high‐(Red), medium‐(Amber), and low‐(Green) priority areas. The application of this procedure allowed several outcomes to be determined: If the concealment occurs at night, then the “search scenario without the visibility” will be the most effective one; if the concealment occurs in daylight, then the “search scenario with the DSM‐based visibility” will be most appropriate; the different search scenarios may be cross‐referenced with offender's confessions and eyewitnesses’ testimonies to verify the veracity of their statements. |
