Aerial images was conducted on
April 8, 2020, using a Mavic 2 Pro (DJI) at an altitude of 130 m with an
overlap rate of 80 % and a sidelap rate of 60 %. The resolution of the
images was 5472×3648 pixel with a ground resolution of 2.94 cm/pixel.
The photogrammetry software used was Photoscan Pro. ver1.3 (Agisoft),
and the resulting orthomosaic image was 4.0 cm/pixel. The kml is a patch
polygon of a Rhododendron reticulatum flower extracted using Picterra,
an online service that uses machine learning.
