LAI Estimations of Coffee Hedges through different methods.

The attached excel file has the datasets for the process described on the paper submitted by Castro-Pacheco et al, with the title "Visual Assessment of Leaf Area Index in Coffee (Coffea arabica L.) Fields."

Two datasets are shown and described.

First, a main dataset containing the results from the the first experimentations done, in which the Leaf Area Index (LAI) was estimated with three different approaches on 80 different sampling points. These approaches were: direct defoliation, visual assesment from trained persons, and through the use of specialized equipment (LICOR LAI-2200C or Accupar LP-80 Ceptometer).

The second -supplementary- dataset corresponds to a second experimentation done, which included 40 sampling points. In these points, LAI was still estimated with the same three approaches, but two different protocols were tested with the instruments.

所附的 Excel 文件包含了由 Castro-Pacheco 等人提交的论文中描述的流程所涉及的数据集，论文题目为《咖啡（Coffea arabica L.）田间叶面积指数的视觉评估》。其中展示了两个数据集及其描述。首先，为主数据集，其中包含了首次实验的结果，该实验中采用三种不同的方法对 80 个不同的采样点进行了叶面积指数（LAI）的估算。这三种方法分别是：直接去叶，经过培训人员的视觉评估，以及通过使用专用设备（LICOR LAI-2200C 或 Accupar LP-80 Ceptometer）。其次，为补充数据集，对应于第二次进行的实验，其中包含 40 个采样点。在这些点，仍采用相同的三个方法对 LAI 进行估算，但测试了两种不同的仪器协议。
