What is WorldView 3?

WorldView 3 is an earth observation satellite (EOS) owned by the American firm DigitalGlobe. It was launched in 2014 and currently provides the highest resolution satellite imagery. It was used recently for counting of several wildlife species including the African elephant. In this new technique, researchers have combined the benefits of satellite imagery and artificial intelligence to improve the accuracy of surveys. The method was tested out at the Addo Elephant National Park, the 3rd largest national park in South Africa.
