Liquidambar orientalis chorology

Distribution map of oriental sweetgum (<i>Liquidambar orientalis</i>)<br><br>These maps were produced by combining numerous and heterogeneous data collected from atlas monographs providing complete species distribution maps, from national to regional atlases, occurrence geo-databases, scientific and grey literature.<br>The maps were created using ESRI shapefiles (*.shp, *.shx, *.dbf, *.prj files) archived in the ZIP file. Species range is mapped with polygon features (name suffix "plg"), which define continuous areas of occupancy of the species, and with point features (name suffix "pnt"), which identify more fragmented and isolated populations. If synanthropic occurrences are reported outside the species natural range, additional point and/or polygon shapefiles are also present (suffix "syn").<br>Polygon borders delimiting species ranges are generalized across the mainland and sea boundaries. This offers the possibility to mask sea areas or to clip and extract the terrestrial range parts using GIS data layers of the users' choice. An additional version of polygon ranges are clipped with a coastline (name suffix "clip"), which have been derived from Natural Earth dataset "Admin 0 - Countries" 1:50M version 4.1.0 (https://www.naturalearthdata.com).<br><br>Please cite as:<br>Caudullo, G., Welk, E., San-Miguel-Ayanz, J., 2017.

东方枫香（*Liquidambar orientalis*）分布地图

本数据集的分布地图通过整合多源异质数据制作而成，这些数据涵盖了提供完整物种分布图谱的国家级至区域级地图集专著、物种出现点地理数据库、科学文献以及灰色文献。

本地图采用存档于ZIP压缩包中的ESRI形状文件（*.shp、*.shx、*.dbf、*.prj）制作。物种分布范围通过两种要素进行可视化：一是多边形要素（文件名后缀为"plg"），用于表征物种的连续分布区域；二是点要素（文件名后缀为"pnt"），用于标识更为破碎和孤立的种群。若在物种自然分布区外存在人为伴生出现记录，则会附带额外的点和/或多边形形状文件（后缀为"syn"）。

用于界定物种分布范围的多边形边界已针对陆地与海洋边界进行了概化处理，支持用户根据自身需求，通过地理信息系统（GIS）数据图层掩膜海洋区域，或裁剪提取陆地分布范围。此外还提供了海岸线裁剪版的多边形范围数据（文件名后缀为"clip"），该数据源自Natural Earth数据集"Admin 0 - Countries"1:50M 4.1.0版本（https://www.naturalearthdata.com）。
