Aerial survey of Hound Bay, South Georgia, elephant seal colony during the 2024/2025 season, flight DLPUS_214_20
Aerial survey of Hound Bay elephant seal colony, Mirounga leonina, during the 2023/24 season conducted using a 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, the original RINEX GNSS (global navigation satellite system) base station files, the post-processed global navigation satellite system and 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_20 which was carried out on 2024-10-25.
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).

Coordinate reference system for outputs:
Projection: UTM Zone 23S
Horizontal datum: WGS84
Vertical datum: MSL (mean sea level), EGM2008 geoid
Resolution of final outputs:
DSM (2.1 cm)
Orthorectified mosaic (2.1 cm)
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.
