Landscape-wide modelling of canopy tree crowns and heights using LiDAR: a case study in the Northern Rivers of NSW, Australia - Tree crown datasets

This dataset provides LiDAR-derived tree crown data for the Northern Rivers region of New South Wales, Australia, as part of the research paper “Landscape-wide modelling of canopy tree crowns and heights using LiDAR: a case study in the Northern Rivers of NSW, Australia” (2025). Australian Journal of Botany. DOI: https://doi.org/10.1071/BT25031 Dataset Contents: The dataset consists of individual crown files (gpkg.zip format store in EPSG:28356) for each Local Government Area (LGA) within the study area. Each file contains the following data for each crown: ID: Unique identifier for each crown. Height: Canopy tree height in meters. Geometry: Polygon geometry defining the crown footprint. Related Resources: GitHub Repository: https://github.com/patrick-m-norman/ALS_regional_forest_modelling This repository contains the scripts and workflows used to process LiDAR data, derive tree height and crowns, and perform boosted regression tree (BRT) modelling. The documentation within the repository details the processing steps and underlying methodology.本数据集为澳大利亚新南威尔士州北河地区提供了激光雷达（LiDAR）反演得到的树冠数据，相关研究成果发表于《澳大利亚植物学杂志》2025年刊发的论文《利用激光雷达开展景观尺度冠层树冠与树高建模：以澳大利亚新南威尔士州北河地区为例》，DOI：https://doi.org/10.1071/BT25031。 数据集内容： 本数据集包含研究区内各地方政府区域（Local Government Area, LGA）的独立树冠文件，文件以gpkg.zip格式存储，坐标系为EPSG:28356。每个文件包含各树冠的如下属性数据： ID：每个树冠的唯一标识符； Height：冠层树木高度，单位为米； Geometry：定义树冠覆盖范围的多边形几何要素。 相关资源： GitHub仓库：https://github.com/patrick-m-norman/ALS_regional_forest_modelling 该仓库包含用于处理激光雷达数据、提取树高与树冠信息并开展提升回归树（Boosted Regression Tree, BRT）建模的脚本与工作流。仓库内的文档详细阐述了数据处理流程与核心方法论。
