The document discusses using profile databases to visualize and communicate 3D relationships in aquifers. It proposes creating multiple cross-sectional profiles from planar GIS surfaces to represent the vertical, or Z, dimension. These profiles could be automatically constructed and linked to the planar data in a standard GIS without additional software. This would allow groundwater managers and the public to easily see and understand the 3D structural relationships important for management.

1. Profile Databases An application in groundwater management “getting to the Z of it all”

2. 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?

3. 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

4. What's important? Communication of these 3D relationships Easy access for resource managers and the community Seeing the structure clearly (show me the “z”)

5. What about using 3D? Powerful visualisation mediums Immersive Highly interactive Looks fantastic! The intuitive choice … well maybe???

6. What about using 3D? Special software / skills / conversion = ($ & time) Updating??? Hidden Information Separate formats Systematic???

7. Deciding what I want? See structure (z) Easy to communicate Augment current business processes Open to a wide user base

8. Deciding what I want? Part of a standard GIS No additional software Automation Wide distribution (WWW) Extend the data model

9. So where to start? An old idea! A good model! Let’s break it down!

10. So where to start? Planar Profile Legend Insert Planar “ Graph”

11. So where to start? Profiles – isn’t that the Z Dimension? Profiles are good at explaining structure Easy to understand & communicate relationships

12. 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

13. So can we?

14. Enter the Profile Database Inputs Transects Transects Profile Database Profile Database automated

15. You are here! Condah Groundwater Management Area

16. Profile Database Bits 60km Trace Transect (section) automated

17. Profile Database Bits 50km automated

18. Profile Database Bits automated Convert “ x” , “y” To “ d” , “z”

19. Profile Database Bits Convert “ x” , “y” To “ d” , “z” automated

20. Profile Database Bits

21. If you really need a 3D hit! surface basement lta surface basement lta

22. If you really need a 3D hit! surface basement lta surface basement lta bores

23. It is GIS…really!

24. It is GIS…really!

25. Remember our “model”?

26. Is that the end? A safe return from the “z” dimension See structure (z) Easy to communicate Augment current processes Open to a wide user base Part of a standard GIS No additional software Automation Wide distribution (WWW) Extend the data model

27. No!…What else can I slice?

28. No!…What else can I slice?

29. What’s next? Concept development Core automation procedures Tool feasibility Tool development

30. This really is the end! Thanks to my team Mina Jahanshahi Luong Tran and [email_address]
