[Geodata] What is the value of free data?

We're in the middle of these same sorts of discussions about making data freely available, both at the City and in the metro area in general. 

Here at the City we use the same system for internal and external access, and the extra costs have thus far been marginal to allowing access.   There are some potential problems with this though in the future, in that if a datasets becomes popular, it may impact bandwidth negatively and cause a rethink of the publishing. 

One big business need that this solves for us, is in being able to see other regional data owners data since they do the same as we do in the publishing department so we can see each others datasets and not have to worry about keeping a local set available and up to date.  While this is not happening across the board with all regional data owners, more and more are coming online all the time. 

A bigger concern is how to share data that is sensitive in nature between jurisdictions, that each agency should have access to but the general public shouldn't.  I know this thread is aimed at the public use, but I would suggest that there are a middle class/level of user, where the data usage needs to be tracked.  Not exactly closed off from viewing, but in many cases for security reasons, the usage needs to be tracked in some form.  This is something that is continuously being wrestled with here.

We are doing the same at NASA.  The problem is that it is not

There is a cost to doing this. As money gets tighter, you need to be 
able to justify it.  Hence the need for the business case.

Asking people may or may not work until you build a value model with a 
fairly solid foundation.

Can we use the economic value of people and infrastructure within an 
image?  I think that there is a value for a human being.
Value of trees...water...???

I think that there are population density and infrastructure density 
maps that could be used and then infer a price tag.

any better idea to can get us to some hard metric?

Anyone with experience in that area?
