I find the optimism of this idea adorable.
Case in point. My city, Dallas, which has no shortage of funds to implement good GIS has this to say about the GIS data they publish.
The accuracy is not to be taken / used as data produced by a Registered Professional Land Surveyor for the State of Texas. For this level of detail, supervision and certification of the produced data by a Registered Land Surveyor for the State of Texas would be required
In other words “Are you kidding? This GIS data is a joke” which explains why there are so many construction related service outages. What kind of resources and GIS quality assurance do you have in your neck of the woods? GIS might get you close, but only close.
