Abies alba chorology

Distribution map of silver fir (<i>Abies alba</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.

欧洲银杉（*Abies alba*）分布图谱

本图谱由多源异构数据整合制作而成，数据来源涵盖发布完整物种分布图谱的图集专著、国家级至区域级森林树种分布图集、物种出现点位地理数据库，以及学术文献与灰色文献。

本图谱以归档于ZIP压缩包中的ESRI形状文件（Shapefile，包含*.shp、*.shx、*.dbf、*.prj格式）为载体。物种分布范围通过两类要素绘制：其一为多边形要素（文件名后缀为“plg”），用于表征物种连续占据的分布区域；其二为点要素（文件名后缀为“pnt”），用于标识更为破碎且孤立的种群。若存在物种自然分布范围之外的人为伴生出现记录，则将附带后缀为“syn”的额外点/多边形形状文件。

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概化处理，使用者可根据需求借助自选的GIS数据图层对海洋区域进行掩膜，或裁剪提取陆地分布范围。本数据集还提供了经海岸线裁剪的多边形范围版本（文件名后缀为“clip”），该版本数据源自Natural Earth数据集“Admin 0 - Countries”1:50M 4.1.0版（https://www.naturalearthdata.com）。
