Danish Groundwater mapping History•Large scale groundwatermapping campain in Denmark•200.000.000 $US spent on mapping and method development•15 years campain ending in 2015
GeoScene3D• The appointed modeling tool by the Danish Ministry of the Environment for
groundwater mapping• Intensively used in Denmark, new models build every month• Used by Public government and local authorities • Used by Private consultants and
Builds on Danish Knowhow on groundwater• Highly specialized software and methods• Proven and tested soulutions for water management• Danish groundwatermapping solutions used Globally• Examples: Indonesia, Thailand, India, Australia, US…

…by I•GISBuilding GeoInformation in GeoScene3D
Need and information overview -> GeoScene3D provides an intuitive understanding
In a full 3D environment, you :• collect and visualize data and other information (geophysical, geotechnical, chemistry, GIS maps, etc.) • build a geological model making use of all available relevant information.
Used for groundwater mapping, contamination mapping, geotechnical applications, infrastructure, geophysical surveys, visualization of complex information
…by I•GISGeological Model Types
Layer based Voxel based
Pro Con
Easy to under-stand
Complex geology hard or not possible
Common way to think geology
Pro Con
Very complex geology can be modeled
Many voxels to deal with (millions)
Fits automatet/ statistical models needs
Can be hardware consuming

GeoInformation Creation and Integration
Databases, maps, scattered information
Stakeholders
Gathering existing data and knowledge
Visualize situation and problems
Collect new data
Build detailed geological model
Use model for groundwater modeling
Communicate results
Project time line
…by I•GISDistributing GeoInformation
I•GIS delivers an integrated platform for building geological models and sharing Geological information.
For building and visualizing geological/geophysical and geotechnical information
For sharing and distributing geoscience data to all Share holders
Municipality
Authorities
Waterworks
…by I•GISGeoCloud
An online data warehouse for geological information accessible from both the web and inside Geoscene3D. Facilitates sharing and distribution of geoscience data and geological models.
…by I•GISLooking forward – Urban Area’s
URBANE GEOLOGY• Massive urbanization – need for more knowledge below the cities• Urban areas – new types information to integrate in the modelling workflow
• Man made structures integrate inito the modelling procedure itself• Smart GeoStatistics – models where information is sparce
GeoSmart Cities: A new paradigm for Geological model building in urbane areas using the city components
…by I•GISLooking Forward – Large Areas
The Geological Expert builds a geological Model basedon available data
The “interpretation typology” is captured in a statistical model on the fly
Based on the statistical model – suggestions for new “interpretation points” is made to the Geologist enabling fast Geological modelling.
MODELLING VERY LARGE AREAS• NEW REQUIREMENTS: larger areas, larger amounts of data, higher level of model detail and
lower experience level of the local workforce in Groundwater mapping.• NEW TOOLS:
• Smart Interpretation – an expert system for the Geological Expert enabling fast modelling of large areas.
…by I•GISPractical Implications of SI: Aid to others
An experienced Geological Expert Builds a geological Model.
The “interpretation typology” is captured in a statistical model
The statistical model can be distributed to other Geologists
And aid others working with similar data on a similar geological setting
