Uncrewed Aircraft Systems (UAS) RGB orthomosaic - Okehampton Bay, Tasmania
This dataset contains UAV RGB imagery collected as part of a field trial to test the Uncrewed Aerial System to be used for the TERN Drone project. The UAS platform is DJI Matrice 300 RTK with 2 sensors: Zenmuse P1 (35 mm) RGB mapping camera and Micasense RedEdge-MX (5-band multispectral sensor). P1 imagery were georeferenced using the onboard GNSS in M300 and the D-RTK 2 Mobile Station. Camera positions were post-processed using <a href=" https://www.ga.gov.au/scientific-topics/positioning-navigation/geodesy/auspos ">AUSPOS</a>. The flight took place between 14:00 and 14:08 at a height of 80m with a flying speed set to 5 m/s. Forward and side overlaps of photographs were set to 80%.

Agisoft Metashape was used to generate this RGB orthomosaic (resolution 1 cm). This cloud optimised GeoTIFF was created using rio command line interface. The coordinate reference system of the orthomosaic is EPSG 7855 - GDA2020 MGA Zone 55.

- Purpose
- The main purpose of collecting this data was to test and establish data processing protocols for the M300 RTK system. The onboard GNSS system enables direct georeferencing, and potentially removes the need for ground control points. The purpose of generating this orthomosaic data product was to test the data upload capacity with TERN Data Services team.

- M300 RTK onboard GNSS used with D-RTK 2 Mobile station was used for georeferencing. Additional control point of the D-RTK Base station added to reduce vertical offset error. Direct georeferencing assessed using Ground Control Point (GCP) panels and Propellor Aeropoints (Leica GS14 used to record GCP coordinates). Raw imagery were processed in Agisoft Metashape.

Resource lineage
- Statement
- Raw data was collected using the Zenmuse P1 RGB mapping camera in a DJI M300 RTK UAS platform. The images were processed in Agisoft Metashape. D-RTK coordinates collected in the field were post-processed using AUSPOS. The updated coordinate was used to shift the camera positions of the P1 camera prior to processing the imagery in Agisoft Metashape. <BR><BR> An orthomosaic of resolution 1 cm was generated and rio command line interface used to create this Cloud optimised GeoTIFF.
