The SkyTEM system is an innovative and technologically advanced airborne geophysical system specifically designed to mapping water resources. This unique technology, capable of mapping the top 500 metres of the Earth in fine detail and in 3 dimensions, was conceived and developed in Denmark, a country with a reputation for environmental care and R&D.
SkyTEM has helped geological organizations and government water agencies on seven continents unearth a wealth of information about their aquifers and aided in their understanding of how geology and mankind can affect, and be affected by, groundwater resources.
Drillling boreholes is not enough for mapping water
In most parts of the world groundwater mapping is based only on one data source – drilling information. A 6 inch borehole represents less than one millionth of acre. This 6 inch borehole will provide precise information about the geology immediately in the vicinity of the hole, but any assumptions made about the surrounding geology is a leap of faith or at best a guess. Drilling boreholes can be expensive particularly when insufficient information is available to determine where to drill and how deep to drill for water. If a large area is being studied, budgets may only allow for limited drilling so selection of where to drill is crucial. Also, access to some areas can be difficult and expensive if the terrain is remote, rugged or heavily vegetated. Limited drilling is often the only option cosidered and low borehole density can result in uncertainties and low confidence levels in geologial interpretations and hydrogeological models.
The SkyTEM airborne method of mappping quickly and economically delivers accurate subsurface data from which location of and depth to aquifers can be revealed.
