Pinus heldreichii chorology

Distribution map of Bosnian pine (<i>Pinus heldreichii</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.

波斯尼亚松（Pinus heldreichii）的分布地图

本套地图通过整合多源异构数据制作而成，数据来源涵盖提供完整物种分布地图的专题图集、国家级至区域级的植物志图集、物种出现点地理数据库，以及学术文献与灰色文献。

本套地图基于归档于ZIP压缩包中的ESRI形状文件（*.shp、*.shx、*.dbf、*.prj）制作而成。物种分布范围通过两类要素制图：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"），用于标识更为破碎且孤立的种群。若在物种自然分布区外存在人为伴生的出现记录，则会附带额外的点或多边形形状文件（后缀为"syn"）。

划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，使用者可根据需求通过GIS数据图层掩膜海洋区域，或裁剪提取陆地分布范围。此外还提供另一版多边形范围文件（文件名后缀为"clip"），该版本已通过Natural Earth数据集"Admin 0 - Countries" 1:50M 4.1.0版（https://www.naturalearthdata.com）的海岸线进行裁剪。
