Assets in mapping for demining	Able to cover large areas, change detection since the 80s	mage acquisition more dependant on cloud conditions, images available also in near infrared	More independant then satelitte sensors from cloud conditions, required a suitable available air-plane, required national authorization	?	Vertical or oblique views of small objects of interest (bunkers, …)
