PeilbuizenGroundwater monitoring wells
This dataset shows groundwater monitoring wells (peilbuizen) and their associated filters as points on a map for the municipality of Hilversum, Netherlands. The source data comes from BRO, the national Key Registry of Subsurface (Basisregistratie Ondergrond), and is updated daily. The dataset contains one map layer, Peilbuizen (monitoring wells), and is maintained as part of Hilversum's open data offering, providing location information on groundwater level measurement points within the municipality.#### Beschrijving Peilbuizen, en bijbehorende filers, in Hilversum als punten op de kaart.
