Adapting geodata and metadata for geodata services in the area of water networks

If you notice that the digital water network does not correspond to the conditions on site, you can report this. This takes the form of an adaptation, supplement or deletion of data (geodata or metadata) on a body of water at the Lower Saxony State Agency for Water Management, Coastal and Nature Conservation. This data is then updated in the digital water network. The water network is a database of water bodies within the state of Lower Saxony. Please note that the information necessary for the information is available. This includes the coordinates of the water section, water body name, water body code, connection to the digital water network and, if necessary, the location sketch and query about regular drying of the water. Missing information can be found online from the Lower Saxony Environmental Card. Your ad is free of charge.
