Amphibians 2023 – spawning water

Has been screen digitalised based on various substrates such as Ortofoto 2019 Stockholm City, the Park Database Stockholm City and Tätortkartatan Stockholm County. Point objects (water collection/dust) from Stockholm Biotop Map 2009 have been added to the layer in the form of circles with a 5 m radius in the places where the objects could not be seen in orthophotos. Information from various amphibian inventories (by the 2018 inventory of environmental management) and observations from the databases ArtArken and the Art Portal have also been added, as well as surveys of spawning water for amphibians for certain areas (Calluna AB). The layer has been supplemented with both objects and attributes based on the environmental administration’s amphibian inventory 2018 and 2023.本数据集已基于多种基底完成屏幕数字化处理，所用基底包括2019年斯德哥尔摩市正射影像（Ortofoto 2019 Stockholm City）、斯德哥尔摩市公园数据库（Park Database Stockholm City）以及斯德哥尔摩郡城镇地图（Tätortkartatan Stockholm County）。针对正射影像中无法识别的点位，已将2009年斯德哥尔摩生境地图（Stockholm Biotop Map 2009）中的点要素（集水点/扬尘点）以半径5米的圆形形式添加至该图层。此外，还补充了多项两栖动物调查数据（源自2018年环境管理调查）、ArtArken数据库与物种门户（Art Portal）的观测记录，以及部分区域的两栖动物产卵水域调查数据（由Calluna AB实施）。本图层还基于当地环境管理部门2018年与2023年的两栖动物调查数据，补充了相关要素与属性信息。
