Customer requests include a wide variety of requests for information. First and foremost is the information from NGOs on the affected population, which can be deduced from the number of buildings, huts or tents. Maps of flood areas, which can be easily mapped using satellite images, are often also required. The mapping of environmental resources and their changes is a classic field of activity in remote sensing and a topic that is also of interest to Médecins Sans Frontières projects, for example to gain information about the distribution areas of mosquitoes. A small proportion of the inquiries relate to the detection of destroyed buildings. However, often only a current satellite image without analysis is ordered, which is used for standard maps.
