Abies borisii-regis chorology

Distribution map of Bulgarian fir (<i>Abies borisii-regis</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 geodatabases and scientific 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>All polygon borders delimiting the range are generalized across the mainland and sea boundaries, and not clipped to a specific coastline. 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. <br><br>Please cite as:<br>Caudullo, G., Welk, E., San-Miguel-Ayanz, J., 2017.

保加利亚冷杉（Abies borisii-regis）分布地图

本套地图通过整合多源异构数据编制而成，数据来源涵盖可提供完整物种分布地图的专题图集、国家级至区域级森林图集、物种出现点地理数据库及科学文献。

本套地图采用存档于ZIP压缩包内的ESRI形状文件（shapefile）制作完成。物种分布范围通过两类地理要素进行制图表达：一是多边形要素（文件名后缀为“plg”），用于划定物种持续分布的连续区域；二是点要素（文件名后缀为“pnt”），用于标识更为破碎孤立的种群。若有物种在自然分布区外的人为伴生出现记录，还会附带额外的点和/或多边形形状文件（后缀为“syn”）。

所有用于划定分布范围的多边形边界已针对大陆与海洋边界进行了概化处理，未裁剪至特定海岸线。这一设置允许用户根据自身需求，通过地理信息系统（Geographic Information System，GIS）数据图层掩膜海洋区域，或裁剪提取陆域分布范围部分。
