I am looking for the communities most useful GIS functions, not just image overlay, searching and styling, deeper broader functions such as finding the cause of a network fault as an example:
Water meter readings from a closed network should all add up, if they don't then theres a fault somewhere, using GIS analyst functions I could narrow down to a section where the water meters no longer add up therefore suggesting a location for the issue.
We currently have a very detailed cad style system but no network node / edge linkage thats workable, I'm looking at ways I can put monetary value on imporving our existing GIS dataset not just a change from now on etc etc... I'm suggesting the cost involved in improving existing dataset will be outweighed by the efficiency and benefits.
I realise this is a fairly basic issue for many I was just hoping for a compiled list of resources for which I can pull support from.
