a Geomorphology of Nagura site with main geomorphic elements superimposed on Google Earth screenshot (© 2020 Maxar Technologies, CNES/Airbus, Google Earth), Yama_1 and Yama_2 are corals studied by Yamaguchi22. Red rectangle: location of (b). b Location of microatolls from total station and RTK-GNSS survey, superimposed on Google Earth screenshot (as in (a)) and drone imagery. Red line: location of the cross-section in (c). c Plot of the absolute altitudes of the corals as measured with RTK-GNSS and total station. Uncertainties on a single coral related to HLS measures and combination of total station and GNSS are of ±5 to ±7 cm (see Method).
