TERN Ecosystem Surveillance: Photopoint Panoramic Images 

Images are taken at sites across Australia by the TERN Ecosystem Surveillance team, using standardized AusPlots methodologies. High-quality digital images are captured using a digital SLR camera at each rangeland vegetation plot. Three photopoints are established configured in an equilateral triangle (2.5 m sides) with the center marked with a star dropper at the center of the plot, and the three photopoints recorded with GNSS/DGPS. At each photopoint a 360° panorama photographic sequence is taken, with up to 40 photographs with a minimum 50% overlap between consecutive photographs. The panoramic photopoint method may be most informative in open forests/woodlands and rangelands. See AusPlots Rangelands Photo-panoramas for more information on this method. 

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. 

Images can be processed to provide 3D reconstructions of each plot which can be used to monitor vegetation change over time to track plot condition as well as providing an estimation of the basal area at the plot level, which can be used to estimate biomass.
