Dec 13, 2018 –<\/strong> Drones can be used to create low-cost and accurate 3D maps ofcoastal areas, new research shows<\/a>.<\/p>\n The technique – developed by the University of Exeter – was tested in beaches where seaturtles nest, allowing scientists to see how rising sea levels will affect them.<\/p>\n It combines drones and photogrammetry (extracting measurements from photographs) with accurate GPS satellite location to create detailed digital models ofcoastal habitats.<\/p>\n Previous methods were either cheap but low in quality, or high-quality but cost thousands of pounds to produce.<\/p>\n Scientists tested the technology at Alagadi in Cyprus – a key nesting site for loggerhead and green turtles – and found that a sealevel rise of 1.2 metres would result in the loss of up to 67% of loggerhead nesting sites and 59% of those used by green turtles.<\/p>\n “Being able to accurately map out terrains in such a fine and local scale is crucial if we want to develop effective conservation strategies,” said lead author Miguel Varela<\/a>, of the Centre of Ecology and Conservation on the University of Exeter’s Penryn Campus in Cornwall.<\/p>\n “Most of the studies on climate change impacts are done on a global scale, but is also crucial to understand what will happen on local areas.<\/p>\n “This method allows us to create realistic digital models that are highly accurate (less than 10cm error). This is a fine scale when compared to global projections.<\/p>\n “It’s ideal forsurveying coastal sites, but could also be applied to other habitats and species, and be used to help identify wildlife protection areas.”<\/p>\n In this case study, the researchers combined their imagery of Algadi’s beaches with data on the location and depth at which turtle eggs are laid.<\/p>\n Professor Brendan Godley<\/a>, who supervised the research, added: “Although some beaches may effectively move inland as sea levels rise, natural and human-made barriers will prevent this is some places.<\/p>\n “Thankfully, we can see from our modelling that our site has resilience and because of good management at our site, there is room for the beach to migrate landwards.”<\/p>\n The paper, published in the journal Global Change Biology<\/em>, is entitled: “Assessing climate change associated sea level rise impacts on sea turtle nesting beaches using drones, photogrammetry and a novel GPS system.”<\/p>\n Media Contact<\/span> Dec 13, 2018 – Drones can be used to create low-cost and accurate 3D maps ofcoastal areas, new research shows.
