Aerial survey of Gold Harbour, South Georgia, elephant seal colony during the 2024/2025 season, flight DLPUS_214_32

Aerial survey of the Gold Harbour elephant seal colony, Mirounga leonina, during the 2023/24 season conducted using a fixed-wing remotely piloted aerial system (RPAS).

The aerial survey was conducted as part of the Darwin Plus (DPLUS) 214 project: Southwest Atlantic Elephant Seal Population Assessment (SAESPA).

Dataset includes the original images and log files, post-processed imagery data, along with the resulting georeferenced DSM (digital surface model) and an orthorectified mosaic of the imagery.

This dataset is from flight number DPLUS_214_32 which was carried out on 2024-11-10.

This work was supported by the Overseas Territories Environment and Climate Fund under Grant Darwin Plus ref: DPLUS214: Southwest Atlantic Elephant Seal Population Assessment (SAESPA).

The camera is placed in the centre of the central component of the drone, with the LiDAR ground sensor immediately below it and offset from the camera. The GNSS antenna is at the front of the drone, offset in the opposite direction.

The sampling rate varied throughout the flight, depending on the speed of the platform.

Calibration was accounted for in processing.
