Acer platanoides chorology

Distribution map of Norway maple (<i>Acer platanoides</i>)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.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).Please cite as:<br>Caudullo, G., Welk, E., San-Miguel-Ayanz, J., 2017.

挪威槭（Acer platanoides）分布数据集
本分布图谱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图谱的国家级至区域级专题地图集专著、区域分布图集、物种出现点地理数据库，以及科学文献与灰色文献（grey literature）。
本数据集以ZIP压缩包归档，内含ESRI形状文件（ESRI shapefiles，含*.shp、*.shx、*.dbf、*.prj格式文件）。
物种分布范围通过两类要素制图：其一为面要素（文件名后缀"plg"），用于界定该物种的连续分布区域；其二为点要素（文件名后缀"pnt"），用于标识更为破碎、孤立的种群。
若存在该物种在自然分布区外的人工伴生种群记录，还将提供额外的点/面形状文件（文件名后缀"syn"）。
面要素的分布边界在大陆与海洋边界处已做概化处理，支持用户通过自选的GIS数据图层对海洋区域进行掩膜，或裁切并提取陆地分布范围。
另有一份经海岸线裁切的面要素分布范围版本（文件名后缀"clip"），其海岸线数据取自1:5000万比例尺的Natural Earth数据集"Admin 0 - Countries"4.1.0版本（https://www.naturalearthdata.com）。
