UAV image and ground data of two citrus 'Valencia' orange (<i>Citrus</i> sinensis [L.] Osbeck) rootstock trials

The data are UAV (Unmanned Aerial Vehicle) and individual tree ground measurements collected from 2 citrus rootstock trials at the U.S. Horticultural Research Laboratory Picos Road farm site, Ft. Pierce, Florida, USA located at 27.437115254946757, -80.42786069428246. The trees in both trials were Valencia sweet orange scion grafted onto various rootstock selections and varieties. The trials are designated as Valencia 5-16 and Valencia 17-28, which indicate the row numbers used for each trial. Valencia 5-16 includes 648 trees and Valencia 17-28 includes 643 trees. The ground data was taken for the 5-16 and 17-28 trials in 2020 and 2021, respectively. The UAV images were taken twice the same day, 5/12/2021, once each under partially sunny (images 27-176) and overcast conditions (images 177-327). A single flight of rows 5-28 for each condition captured both trials. Some of the images under the partially sunny condition show tree shadows when the sun was not obscured behind a cloud, whereas the images under the overcast condition flight have uniform lighting and no sun shadows. Each image is notated to designate the flight condition. For example, the image labeled <strong>DJI_0033_R5-R28_Valencia_sunny.JPG</strong> was taken from the partially sunny flight and the image labeled <strong>DJI_0183_R5-R28_Valencia_overcast.JPG</strong> was taken from the overcast flight. The UAV images were taken using a DJI Phantom 4 Pro drone using a side-overlap of 80% and a forward-overlap of 80% of the flight lines. The images are suitable for orthorectification. The images were red-green-blue (sRGB) in a 3:2 format with 5472 x 3648 pixels. The dataset is included in one folder that contains 305 files – 301 image files, 2 Excel spreadsheets (one for each trial) that contain the planting plan and ground measures, and 2 images with the rows and tree spaces labeled. The 2 labeled images are composite images constructed from the 150 images from the overcast set and were created to label rows and tree space numbers. The composite image is useful for general orientation and matching the individual trees to the ground data and other post-processing image analyses.

本数据集包含无人机（Unmanned Aerial Vehicle, UAV）采集数据与单木地面实测数据，采集自美国佛罗里达州皮尔斯堡的美国园艺研究实验室皮克斯路农场场地（坐标为27.437115254946757, -80.42786069428246）的2项柑橘砧木试验。两项试验中的果树均为以瓦伦西亚甜橙作为接穗，嫁接于不同砧木选系与品种的植株。两项试验分别命名为Valencia 5-16与Valencia 17-28，其编号对应各自试验所用的行号；其中Valencia 5-16试验包含648株果树，Valencia 17-28试验包含643株果树。地面实测数据分别于2020年与2021年针对5-16与17-28试验完成采集。无人机影像于2021年5月12日单日完成两次飞行采集，分别在晴间多云（影像编号27-176）与阴天（影像编号177-327）两种光照条件下拍摄；单次飞行覆盖行号5-28的区域，可同时覆盖两项试验。晴间多云条件下拍摄的部分影像中，当太阳未被云层遮挡时会出现树木阴影，而阴天飞行拍摄的影像光照均匀，无太阳阴影。每张影像均标注了其对应的飞行光照条件，例如名为**DJI_0033_R5-R28_Valencia_sunny.JPG**的影像采集自晴间多云飞行任务，名为**DJI_0183_R5-R28_Valencia_overcast.JPG**的影像则采集自阴天飞行任务。本次影像采集使用DJI Phantom 4 Pro无人机，飞行航线的旁向重叠度与航向重叠度均为80%，采集的影像可用于正射校正。影像为红绿蓝（sRGB）色彩模式，画幅比例为3:2，分辨率为5472×3648像素。本数据集收纳于单个文件夹中，共包含305个文件：301个影像文件、2份Excel表格（分别对应两项试验，包含种植规划与地面实测数据），以及2张标注了行号与树间距的标注影像。该2张标注影像由阴天影像集中的150张影像合成制作，用于标注行号与树间距编号，可用于整体场景定位、单木与地面实测数据的匹配，以及其他影像后处理分析工作。
