The University of Ballarat projectthat federates groundwater data from disparate sources to assist groundwater researchers and help water managers make the correct choices for the sustainable use of a precious resource is making significant progress.

2. About the project
An interoperable web-GIS that federates groundwater data from
disparate sources to assist water managers make the correct choices
for the sustainable use of a precious resource
• Use high-speed broadband to:
– Distribute groundwater bore data
– Visualise groundwater data
– Model groundwater systems on-the-fly

3. Partners

4. About the project
• Design Methodology
– Data resides with the data managers
– Intuitive to use (e.g. Google Earth)
– Allow data downloads (subject to data manager’s consent)
– Link spatial data to original documents and images
– Link spatial data to real time data (data loggers, webcams)
– Capable of generating models on the fly
– Allow users to add, edit or update data (subject to QA/QC)
– Spatial data and models should be credible to the user
