“getting to the Z of it all”

What's the Problem?What's the Problem?

• Aquifers are 3D in nature

• A stack of related structural units

• Vertical structure or relationships are an

important

• New “mapping” at higher resolutions

• Such relationships are difficult in (planar) GIS

Difficult…mmm…..Or is it?

The basics!The basics!

• GIS is all about graphs

• Standard GIS is a graph of “x” and “y” viewed from above – planar

• The Z dimension is an issue for this framework

What's important?What's important?

• Communication of these 3D relationships

• Easy access for resource managers and the community

• Seeing the structure clearly(show me the “z”)

What about using 3D?What about using 3D?

• Powerful visualisation mediums

• Immersive

• Highly interactive

• Looks fantastic!

The intuitive choice

… well maybe???

• Special software / skills / conversion = ($ & time)

• Updating???

• Hidden Information

• Separate formats

• Systematic???

• Profiles – isn’t that the Z Dimension?

• Profiles are good at explaining structure

• Easy to understand & communicate relationships

So can we?So can we?

• Create multiple profiles (x-sections) from planar GIS surfaces

• Automate the construction of sections

• Have a relationship between planar and profile views

• Do all this in a standard GIS
