Spatial Database of Pondscapes

The spatial distribution of the pondscapes in Europe were obtained from global and local databases and presented in deliverable D3.2 (report on spatial distribution of pondscapes in Europe). However, the information was too coarse and necessary features of the ponds could not be retrieved from the available local databases. Therefore, available datasets from each participant country were collected and a common database was created. This database consists of spatial information such as latitude and longitude of the ponds in geographic coordinates, name, code, land cover, intensity, hydro period, surface area, perimeter, maximum depth, mean depth, altitude, measurement year, created year, information about work packages and installed sensor information. 

Geocoded and detailed GIS layers showing all ponds were created and it will be used as ground truth for mapping and validating hydro period information. A web application has been developed to display spatial distribution and available information of ponds from the individual countries. The application allows users to dynamically visualize the ponds and download pond’s available data, hydro period information and pond database spatially: https://ponderful.hidrosaf.com/.

欧洲池塘景观的空间分布数据源自全球及本地数据库，相关成果已在交付成果D3.2（《欧洲池塘景观空间分布报告》）中呈现。但现有数据分辨率过于粗糙，且无法从已有本地数据库中提取池塘的必要特征。为此，项目团队收集了各参与国的可用数据集，构建了一套通用数据库。该数据库涵盖池塘的各类空间信息，包括地理坐标系下的经纬度、名称、编码、土地覆盖类型、开发强度、水文周期、表面积、周长、最大水深、平均水深、海拔高度、测量年份、创建年份、工作包相关信息，以及已安装传感器的相关参数。

研究团队还构建了包含所有池塘的地理编码详细地理信息系统（Geographic Information System, GIS）图层，该图层将作为绘制和验证水文周期信息的地面真值数据。

项目还开发了一款Web应用程序，用于展示各参与国池塘的空间分布及可用信息。该应用支持用户动态可视化池塘分布，并可下载池塘的各类可用数据、水文周期信息及空间化的池塘数据库：https://ponderful.hidrosaf.com/
