Result types

The overlay offers the following result types:

Result type Unit Description
SUBSIDENCE m change in land height The amount that the ground has lowered as a result of subsidence, both oxidation and compaction. A positive number means the ground has lowered.
OXIDATION m change in land height The amount that the ground has lowered as a result of peat oxidation.
SETTLEMENT m change in land height The amount that the ground has lowered as a result of compaction.
HI_GROUND_WATER m distance from surface to groundwater The distance between the ground surface and the highest groundwater level. This number is lower than that of the lowest groundwater level. A positive value means the groundwater is below the surface of the land. A negative value would theoretically mean the groundwater has risen above the surface of the ground.
LOW_GROUND_WATER m distance from surface to groundwater The distance between the ground surface and the lowest groundwater level. This number is higher than that of the highest groundwater level. A positive value means the groundwater is below the surface of the land. A negative value would theoretically mean the groundwater has risen above the surface of the ground.
