Rothera Point Orthomosaic 2026-04-02

The orthomosaic was generated from UAV imagery captured by the BAS Engineering Team at Rothera Research Station.

Instrumentation

UAV model:

• DJI Mavic 3 Enterprise

• Mechanical shutter speed: 8–1/2000 s
• Maximum image size: 5280 × 3956 pixels

Data processing and accuracy

The orthomosaic was produced through photogrammetric processing of the UAV imagery and exported in the UTM Zone 19S coordinate system.

No surveyed Ground Control Points were used during the processing. The dataset was therefore georeferenced using the UAV’s internal positional information only.

No independent accuracy assessment was undertaken; therefore, the positional accuracy of the dataset has not been independently verified. As the imagery was not acquired or processed for accurate mapping or survey purposes, no Ground Sampling Distance (GSD) has been specified, and no photogrammetric processing or accuracy report is available for this item.
