An update to the Antarctic Specially Protected Areas (ASPAs) March 2016

Two shapefiles are contained in this update on the location and extent of Antarctic Specially Protected Areas (ASPAs). The first is a point file (centroids of ASPA locations) and the second i sa polygon file showing the spatial extent and boundary of each ASPA. This update builds on the point and polygon files originally provided by Environmental Research and Assessment (2011). The update includes the removal of ASPAs that have been de-designated and new ASPAs that have been designated since 2011. New ASPA boundaries were created from coordinates provided in the management plans.

本次更新包含两份用于呈现南极特别保护区（Antarctic Specially Protected Areas, ASPAs）位置与范围的形状文件（shapefile）。其中第一份为点要素文件，存储各ASPA的位置质心；第二份为多边形要素文件，展示各ASPA的空间范围与边界。本次更新以环境研究与评估机构（Environmental Research and Assessment）2011年最初提供的点要素与多边形要素文件为基础进行更新。本次更新移除了2011年之后已被撤销指定的ASPA，并新增了同期获批设立的ASPA。新增ASPA的边界依据其管理计划中提供的坐标信息生成。
