Victorian Wetland Inventory (Pre-European)

Polygons showing the extent of wetlands in Victoria prior to European settlement. Includes all wetlands from Wetland_1788 and naturally occurring wetlands that were added to the updated current wetland extent (WETLAND_CURRENT). Where available original Corrick classification (primary categories based on water and salinity regimes) were retained. The polygon boundaries were derived from aerial photography interpretation. The most recent update to this database was in 2021.本数据集包含展示维多利亚州欧洲殖民前湿地分布范围的多边形矢量数据。其涵盖源自Wetland_1788的全部湿地，以及被纳入更新后的现行湿地范围（WETLAND_CURRENT）的天然湿地。若可获取相关资料，则保留原始的科里克分类法（Corrick classification）——该分类法以水文动态与盐度状况为依据划分湿地主要类别。该多边形的边界通过航空摄影解译方式获取。本数据库的最近一次更新于2021年完成。
