UAS RGB Orthomosaic of Okehampton Bay, Tasmania at 1 cm Resolution

DJI Matrice 300 RTK drone imagery collected during a 2026 field trial for the TERN Drone project. An RGB orthomosaic was generated from 80m altitude flights using a Zenmuse P1 camera, achieving 1 cm resolution and georeferenced with onboard GNSS and post-processed AUSPOS positions. The final cloud-optimized GeoTIFF is provided in the GDA2020 MGA Zone 55 coordinate system.

Use Cases

• Coastal landform and vegetation mapping based on the 1 cm resolution RGB orthomosaic.
• Testing photogrammetry and orthomosaic generation workflows based on the described UAS platform and sensor specifications.
• Geospatial analysis and basemap creation based on the high-precision, georeferenced imagery in EPSG:7855.
• Calibrating or validating other remote sensing data based on the high-resolution ground reference.

Strengths

• High 1 cm spatial resolution from an 80m flight altitude.
• Precise georeferencing using onboard GNSS and post-processed AUSPOS camera positions.
• Standardized coordinate reference system (EPSG:7855 - GDA2020 MGA Zone 55).
• Detailed acquisition parameters provided, including 80% forward/side overlap and 5 m/s flight speed.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects a single geographic location (Okehampton Bay) and a very narrow temporal window (8-minute flight).
