Estimating the age of Eucalyptus plantations using monthly harmonized Landsat-Sentinel imagery and a LandTrendr-based workflow

This repository contains the core data and workflow files supporting the manuscript Estimating the age of Eucalyptus plantations using monthly Harmonized Landsat–Sentinel imagery and a LandTrendr-based workflow. The deposited files include: (1) a monthly fused HLS image used for analysis, (2) the Eucalyptus plantation classification result, (3) the final harvest-date output derived from the adapted LandTrendr workflow, (4) training and validation sample data, (5) the study-area boundary, (6) a README file describing the file structure and dataset organisation, and (7) two text-format Google Earth Engine workflow files, one for monthly HLS compositing/reconstruction and one for the LandTrendr-based harvest-detection procedure. Together, these files allow inspection of the dataset organisation and support reproducibility of the main workflow and results reported in the manuscript. All files are openly shared under the CC BY 4.0 licence.本仓库包含支撑论文《基于月度Harmonized Landsat–Sentinel（HLS）影像与LandTrendr流程估算桉树林分林龄》的核心数据与工作流文件。所归档文件如下：(1) 用于分析的月度融合HLS影像；(2) 桉树林分分类结果；(3) 经适配的LandTrendr流程产出的最终收获日期数据；(4) 训练与验证样本数据集；(5) 研究区边界文件；(6) 用于说明文件结构与数据集组织方式的README文档；(7) 两份文本格式的Google Earth Engine（GEE）工作流文件，分别用于月度HLS影像的合成与重构，以及基于LandTrendr的收获事件检测流程。上述文件可用于检视本数据集的组织形式，并支撑论文中报道的核心工作流与研究结果的复现。所有文件均采用CC BY 4.0开源许可协议公开共享。
