Aerial images collected by UAV, Aldabra gigi, Seychelles - 20221024 - 02_31
收藏资源简介:
"This dataset was collected by an Unmanned Aerial Vehicle in Aldabra gigi, Seychelles, on 20221024 Underwater or aerial images collected by scientists or citizens can have a wide variety of uses for science, ecosystems management, or conservation. These images can be annotated and shared to train IA models which can in turn predict the objects on such images. We provide a set of tools (hardware and software) to collect marine data, predict species or habitat, and provide maps. The depot consists of the following elements: - 00_: Image preview panel - DCIM.zip: RAW images from UAV - GPS.zip: GIS file (Geopackage) containing the overflight area as well as the geolocation of the images accompanied by their thumbnails in the base64 attribute table. - METADATA.zip: Exif metadata in CSV format, OGC metadata in ISO19115 / 39 XML format, flight reports with thumbnails of drone images (tb folder) and flight statistics (html or pdf files).
