Reading soil and elevation without false precision
The soil map and elevation view help explain a location. They answer different questions and have their own scale, coverage and source dates.
A soil type is regional context
The BRO Soil Map describes soil profiles in mapped areas, generally down to 1.2 metres. Its survey scale is 1:50,000. Zooming in does not increase the detail of the source information. Urban areas often have no soil information; missing coverage does not mean the ground has been investigated and found suitable.
Read overlap by mapped area
The parcel map compares complete parcel geometry with soil polygons. The displayed area is their overlap. If a mapped area describes several soil units, those units share the same area. They are not independent layers to add together. Use the result for initial orientation and read the BRO explanation before treating a classification code as a measurement at your location.
Elevation is not a ground investigation
The AHN elevation view displays a derived terrain surface referenced to NAP. The map interpolates between available raster values; missing values remain unknown. Elevation is different from groundwater level and does not predict flooding on its own. Foundations, contamination, drainage and building plans need other investigations and current local information. Compare sources and their dates, and obtain site-specific investigations when your decision depends on them.
