Continental HydroLAKES Subset Shapefiles (Africa, Asia, Australia, Europe, Eurasia, Holarctic, Indo-Pacific, North America, South America, New World, Old World)
收藏资源简介：
This dataset provides continental and regional subsets of the HydroLAKES v1.0 global lake polygon database (Lehner & Messager 2016) for use in large-scale environmental and ecological modeling workflows. The original HydroLAKES dataset was obtained from the HydroSHEDS data portal (hydrosheds.org/page/hydrolakes) and includes approximately 1.4 million individual lake polygons (surface area ≥ 10 ha) derived from HydroSHEDS and Hydro1K elevation data. To facilitate faster processing and region-specific analyses, the full global shapefile was spatially partitioned into eleven continental subsets based on predefined geographic extents: Africa, Asia, Australia, Europe, Eurasia, Holarctic, Indo-Pacific, North America, South America, New World, and Old World. Each subset was generated using bounding boxes consistent with other continental datasets in this project (for example, Copernicus GLO-90 DEM), ensuring spatial compatibility across environmental variables. All subsets are stored as compressed ESRI Shapefiles (.zip archives) containing the standard .shp, .dbf, .shx, and .prj components. Each file preserves the original HydroLAKES attribute fields (such as LakeID, CenterLat, CenterLong, Lake_area, Depth_avg, Depth_max, etc.) and retains the WGS84 geographic coordinate reference system (EPSG:4326). Users can load the data directly in GIS software (such as QGIS or ArcGIS) or within R using the functions terra::vect() or sf::st_read(). These subsets are particularly suitable for regional filtering of inland water bodies prior to background masking or terrain analysis in species distribution, hydrological, and landscape modeling applications.

本数据集提供了HydroLAKES v1.0全球湖泊多边形数据库（HydroLAKES v1.0，Lehner & Messager 2016）的大陆及区域子集，适用于大规模环境与生态建模工作流。原始HydroLAKES数据集获取自HydroSHEDS数据门户（hydrosheds.org/page/hydrolakes），包含约140万个独立湖泊多边形（表面积≥10公顷），数据源自HydroSHEDS与Hydro1K高程数据集。 为加快处理速度并支持区域针对性分析，完整全球形状文件被基于预定义地理范围空间划分为11个大陆子集，分别为非洲、亚洲、澳大利亚、欧洲、欧亚大陆、全北极区、印太区、北美洲、南美洲、新大陆、旧大陆。每个子集均采用与本项目中其他大陆数据集（如哥白尼GLO-90数字高程模型（Copernicus GLO-90 DEM））一致的边界框（bounding box），确保与各类环境变量具备空间兼容性。 所有子集均以压缩的ESRI形状文件（ESRI Shapefile）格式存储，即.zip压缩包，内含标准的.shp、.dbf、.shx与.prj文件组件。每个文件均保留了原始HydroLAKES的属性字段，例如LakeID、CenterLat、CenterLong、Lake_area、平均水深（Depth_avg）、最大水深（Depth_max）等，并采用WGS84地理坐标系（EPSG:4326）。 用户可直接在GIS软件（如QGIS或ArcGIS）中加载数据，或在R语言环境中通过terra::vect()或sf::st_read()函数读取。该子集特别适用于在物种分布、水文与景观建模应用中进行背景掩膜或地形分析前，对内陆水体开展区域筛选。 数据来源：HydroLAKES v1.0，HydroSHEDS数据库 — hydrosheds.org/page/hydrolakes 引用格式：Lehner, B. 与 Messager, M.L.（2016）.
