Google Earth Engine——世界保护区数据库（点元素）（WDPA）是关于保护区的最新和最完整的信息来源，每月根据政府、非政府组织、土地所有者和社区提交的信息进行更新。

The World Database on Protected Areas (WDPA) is the most up-to-date and complete source of information on protected areas, updated monthly with submissions from governments, non-governmental organizations, landowners, and communities. It is managed by the United Nations Environment Programme's World Conservation Monitoring Centre (UNEP-WCMC) with support from IUCN and its World Commission on Protected Areas (WCPA).

WDPA User Manual. For details including methodologies,standards, data providers, metadata field definitions and descriptions, refer to the WDPA User Manual.

The WDPA has two feature classes with associated spatial and tabular data on more than 200k protected areas. About 91% contain polygon boundaries, with the remaining only as points, representing the center of the protected area as much as possible.

Asset Naming Conventions. WCMC updates the WDPA on a monthly basis. The most recent version is always available as WCMC/WDPA/current/polygons and WCMC/WDPA/current/points. Historical versions, starting with July 2017, are available in the format WCMC/WDPA/YYYYMM/polygons and WCMC/WDPA/YYYYMM/points.

Please see the WDPA User Manual for additional details on the field list.

世界保护区数据库（WDPA）是关于保护区的最新和最完整的信息来源，每月根据政府、非政府组织、土地所有者和社区提交的信息进行更新。它由联合国环境规划署的世界保护监测中心（UNEP-WCMC）管理，并得到世界自然保护联盟及其世界保护区委员会（WCPA）的支持。

WDPA用户手册。有关细节，包括方法、标准、数据提供者、元数据字段定义和描述，请参阅WDPA用户手册。

WDPA有两个特征类别，其中有超过20万个保护区的相关空间和表格数据。大约91%包含多边形边界，其余的仅为点，尽可能代表保护区的中心。

资产命名规则。WCMC每月都会更新WDPA。最新的版本总是以WCMC/WDPA/current/polygons和WCMC/WDPA/current/points的形式提供。历史版本，从2017年7月开始，以WCMC/WDPA/YYYYMM/多边形和WCMC/WDPA/YYYYMM/点的格式提供。
