Rijkswaterstaat Water Quantities Catalogue

rijkswaterstaatwaterwebservices/list-quantities

Lists the quantities Rijkswaterstaat measures, as pairs of compartment code (for example OW surface water, LT air, ZS sea) and quantity code (for example WATHTE water level, T temperature, Hm0 wave height), with the Dutch description of each, which names the quantity, the compartment and the unit. Use a pair as the compartment and quantity inputs of rijkswaterstaatwaterwebservices/get-observations. The list is the full catalogue of about 160 pairs. Public water data from Rijkswaterstaat published under CC0, served by Eden Engine; not an official Rijkswaterstaat product.
