Using super‐high resolution satellite imagery to census threatened albatrosses
This study is the first to utilize 30‐cm resolution imagery from the WorldView‐3 ( WV ‐3) satellite to count wildlife directly. We test the accuracy of the satellite method for directly counting individuals at a well‐studied colony of Wandering Albatross Diomedea exulans at South Georgia, and then a...
