Technical datasheet - Overflight for manual photographingObjective: Data acquisition to manually quantify and determine types of boats mooringor sailing in the MPA.Remark : the method described below is entirely manual for the sake of easy implementation. High-tech automaticmethods developed by specialized firms do, however, exist.Overflight preparationIs it possible to fly over the MPA : before considering an overflight of your MPA, make sure that no regulationsprohibit or control (applying for authorisation) overflying the study zone (military or environmental regulation forexample).Choice of aircraft : irrespective of the kind of aircraft chosen, the operator must make sure that it offers good visibilityfor taking aerial photographs. ULMs or high-wing monoplanes should therefore be preferred.Choice of photography equipment: a digital camera with a resolution of at least six million pixels allows boats to beidentified during post-processing. The camera must also be responsive, i.e. with short trigger and waiting time betweentwo photographs.Flight plan : a flight plan must be prepared and approved by the pilot and the photographer before the flight. The flightplan must be adapted to the site and to the aim of the flight. The plan must also avoid photographs being taken into thelight, allow an identifiable land part to be included in each wide-angle shot and avoid double counts.Precautions for aerial photographs during the overflightFlying speed and altitude : flying speed must be reduced and, depending on the aim of the flight, the aircraft will fly atapproximately 1,000 feet for simple boat counting and locating or at 500 feet to determine the type of boats from theshots taken.Taking shots : photographs can be used to quantify, characterise and spatialise boats in the MPA. Several hundredpictures can rapidly be taken during one overflight. The photographer must therefore bear in mind that a small numberof pictures will facilitate manual post-processing.Therefore, the photographer will opt for wide-angle shots including a land part in order to locate the photo. Boats will beidentified by zooming in on them when analysing the image.Manual photo processing and analysis: example of Porquerolles Island (France)1Porquerolles IslandN0 1 Km1 234Delimitation and coding of the MPA's mooring orsailing areas.
