UAS RGB Orthomosaic of Cockatoo Hills, Tasmania at 1 cm Resolution

Terrestrial Ecosystem Research Network's TERN Drone project field trial data includes an RGB orthomosaic generated from UAV imagery. The imagery was collected by a DJI Matrice 300 RTK with a Zenmuse P1 camera at 80 m flying height between 10:26 am and 10:47 am AEDT. The final orthomosaic has a 1 cm resolution and uses the EPSG 7855 coordinate reference system.

Use Cases

• High-resolution land cover classification based on the 1 cm RGB orthomosaic.
• Validation of satellite or other aerial data products based on the georeferenced UAV imagery.
• Training object detection models for ecological features based on the detailed visual data.
• Creating baseline maps for environmental change studies based on the spatially referenced imagery.

Strengths

• Imagery has a very high spatial resolution of 1 centimeter.
• Georeferencing used post-processed camera positions from AUSPOS and an onboard GNSS with D-RTK 2 Mobile Station.
• Flight parameters are specified, including 80 m flying height and 80% forward and side overlap.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's single time and location may reflect geographic and temporal bias.
