Wetland inventory VMI: Vectorised Objects 2021 to xx

The Wetland Inventory (VMI) was conducted 1981-2005. All inventored wetlands have been aerial image interpreters and this is documented on interpretation sketches. The exception is Norrbotten County, which performed the aerial interpretation digitally from the beginning. Work on geocorrecting the interpretation sketches and making them digitally available (in break format) has been ongoing since 2019 and is expected to be completed in 2022. The results are available through the Environmental Data Portal. The geo-corrected interpretation sketches (rasters) have now started to be converted into vector GIS layers, both for the delimitation of objects and sub-objects as well as internal objects fixedland islands and water. In addition, more attribute data has been included compared to the vector layer 2010. It is still unclear when the work for all counties will be completed. Download files are gradually added under each county in subfolder "5. GIS layer. For download, there is today object layer 2021 for Uppsala County.湿地调查（Wetland Inventory, VMI）于1981年至2005年间开展。所有纳入调查的湿地均已完成航空影像解译，相关工作记录于解译草图中。唯有北博滕县（Norrbotten County）自项目启动之初便采用数字化方式开展航空解译。自2019年起，针对解译草图开展地理校正并将其以断点格式（break format）数字化归档的工作持续推进，预计2022年完成。相关成果可通过环境数据门户获取。 经地理校正的解译草图（栅格数据 (rasters)）目前已开始转换为矢量地理信息系统（Geographic Information System, GIS）图层，既用于地物及其子对象的边界划定，也用于固定陆岛与水域等内部地物的标注。相较于2010版矢量图层，本次数据集新增了更多属性数据。目前仍无法明确全部县的此项工作完成时间。 下载文件正逐步按县归类至子文件夹"5. GIS图层"下。目前可下载的数据集包含乌普萨拉县（Uppsala County）2021版地物图层。
