UAS Multispectral Orthomosaic of Okehampton Bay, Tasmania at 5 cm Resolution

A 5-band multispectral orthomosaic with 5 cm resolution was generated from UAV imagery collected for the TERN Drone project. The Terrestrial Ecosystem Research Network's Data Discovery platform published this cloud-optimised GeoTIFF, which contains relative reflectance values for Blue, Green, Red, Red Edge, and NIR bands. Flights were conducted at 80m altitude using a DJI Matrice 300 RTK equipped with a Zenmuse P1 camera and a Micasense RedEdge-MX sensor.

Use Cases

• Calculate vegetation indices like NDVI based on the Red and Near-Infrared (NIR) reflectance bands.
• Perform land cover classification for coastal areas using the five spectral bands (Blue, Green, Red, Red Edge, NIR).
• Conduct precision agriculture or ecological monitoring based on high-resolution (5 cm) multispectral imagery.
• Test and validate drone-based remote sensing workflows for environmental data collection.

Strengths

• High spatial resolution of 5 cm per pixel for detailed analysis.
• Contains five calibrated spectral bands (Blue, Green, Red, Red Edge, NIR) for multispectral applications.
• Imagery was collected with professional-grade equipment (DJI Matrice 300 RTK, Zenmuse P1, Micasense RedEdge-MX) and processed using a standard photogrammetry workflow.
• Data is provided as a cloud-optimised GeoTIFF (COG) in a defined coordinate reference system (EPSG 7855).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; band order and data semantics must be inferred from the description.
• The temporal coverage is limited to a single flight period on one day.
