The Signalering Map Soil Drop shows which areas are (strong) subsidence sensitive in the Province of Zuid-Holland (PZH). For this purpose, several detailed maps have been used and aggregated into one qualitative interpretation. A simplification of reality, but one that signals where the local reality is susceptible to subsidence. This knowledge is important for above- and underground spatial developments; to avoid costs and inconvenience, or to capitalise on opportunities.
The total map is made up of hexagones of 250 meters, in which information is pooled from the underlying maps “stability”, “veen oxidation” and “carrying force”. The hexagones made this aggregation technically possible and prevent the information from being used at parcel level.
This map is accessed directly from the website Signage maps Soil and Underground of the Province of South Holland. Here you can also find the underlying maps including substantive explanations per map.
