At present , urbanisation is taking place . A s cities expand ,
areas previously omitted due to construction risks are now
being urbanised. These areas are typically characterised as
those with unforeseen soil properties , unknown
groundwater conditions and the risk of flooding from the
sea or rivers . Thus, to utilise these areas urban planners
need detail ed information about the geology, hydrology
and future climate impact on the area. W e have
investigated how high-density geophysical data in
combination with geotechnical data , borehole data and
GIS data could be used for develop ing a high-resolution ,
3D geological voxel model for Ny Rosborg. I n this
model , specific geotechnical values can be assigned to
each voxel thus providing a 3D overview of the
geotechnical properties of the study area. The 3D
geotechnical model enables city planners to identify those
areas that are the most sustainable and cost-effective to
develop . The 3D model output was combined with a map
showing areas prone to flooding enabling the construction
of a series of planning maps show ing the most suitable
locations for green areas ( such as parks), blue areas ( such
as lakes or wetlands) and grey areas ( such as buildings or
roads) within the Ny Rosborg area.
