Indicators of Mine Presence: Focus on trenches

As of October 2013, some 59 states and four other areas were confirmed to bemine‐affected. Large "Suspected Hazardous Areas'', often overestimated, prevent thepopulation to use the land. In this context, aerial images provide an asset for a betterdelineation, based on indicators of mine presence (IMP) or of mine absence. Trenchesdetected thanks to their shadows are good examples of IMP. Their sparse presence over thehuge amount of images makes their detection by a photo‐interpreter an overwhelming task.We therefore propose an automatic tool based on dark line detection. In various envisagedscenarios, the most suspicious images and the detected objects are proposed to photointerpretersfor further analysis or for pre‐processing such as ortho‐photo production. Thetool is applied to the Suspected Hazardous Area of Bihac in Bosnia and Herzegovina.
