Terrestrial laser scanning of forest plot HV011, Hidden Vale, Queensland, Australia (May 2026)

Terrestrial laser scanning of forest plot HV011, Hidden Vale, Queensland, Australia (May 2026) This dataset contains terrestrial laser scanning (TLS) single scans of forest plot HV011 at Hidden Vale, south-east Queensland, Australia (approx. 27.711° S, 152.466° E), acquired on 26 May 2026 with a RIEGL VZ-600i from 140 scan positions. Scanner settings All scans used identical settings: RIEGL VZ-600i, 2200 kHz pulse repetition rate, 0.034 degree angular resolution in azimuth and zenith (approx. 5.9 mm point spacing at 10 m), 360 degree x 25-130 degree zenith field of view, 25.2 s per scan, upright mounting. Processing Scans were registered in RIEGL RiSCAN PRO using multi-station adjustment and georeferenced using the scanner's GNSS, post-processed against the Rosevale (ROSV) continuously operating reference station. The neighbouring plot HV010 uses the same base-station coordinates, so both plots share one geodetic frame. Contents - Single scans: one LAZ file (LAS 1.4) per scan position, in the scanner's own coordinate system (SOCS), with all attributes retained (intensity, GPS time, amplitude, reflectance, pulse-shape deviation). Packaged in three zip archives. Points were filtered at export to reflectance -25 to +5 dB, pulse-shape deviation <= 12 and range 2–75 m. The LAS Intensity field is a linear rescaling of RIEGL calibrated reflectance (the filtered -25 dB to +5 dB window mapped to 0–65535; Intensity = (Reflectance + 25) / 30 x 65535), not raw amplitude; reflectance (dB), amplitude (dB) and pulse-shape deviation are also provided as LAS extra bytes.- Transformation matrices: 4x4 matrices for each scan from SOCS to the project coordinate system (PRCS) and from SOCS to geocentric ECEF (EPSG:4978), plus the project PRCS to ECEF matrix.- Metadata: RiSCAN PRO registration report(s) and scan position coordinates.- README describing coordinate systems, file formats and how to apply the transformations, and MD5 checksums of every file inside the archives. Related data Merged, clipped and 2 cm subsampled/denoised plot point clouds derived from these scans are available on 3DTrees (https://3dtrees.earth). Plot HV010 is published as a separate record.
