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
