Google Maps as Mapserver Layer

Puneet -

The chief difficulty is when cash-strapped state and local governments
eagerly provide data to Google (much as was done with Microsoft
TerraServer) and then think they've "solved the problem" because "look
how everyone can get it in Google Earth!".  That can make it hard to get
funding for a state GIS program to, for example, properly set up and
operate a WMS service for access to the same data - the budget-cutter
wonder why they should pay for something they "already have for free".
There's no problem with states providing data to any private firm.  The
problem is when the providing organization misunderstands what it has
accomplished.

The USGS learned a few lessons in the TerraServer experience; I expect
other organizations are simply beginning the process of re-learning some
of those lessons all over again.

this is getting quite OT for MapServer, but what the heck --

but, you do have access to the data. I just checked the Arkansas site
that Paul provided below, and besides a bunch of innocuous factual
errors, they clearly point to the repository where all that data are
still available for anyone to use. Of course, the linked site
<http://www.rgis.cast.uark.edu/> is non-functional, so I guess I am
better off using Google Maps ;-)

Think of it this way... the US has a long history of offering publicly
collected data to anyone for no or minimal cost, and that anyone has the
freedom to do anything they want to with that data, including selling it
back to the US! I, for one, am very happy of this policy.

And, so are the mapping companies, for this is what they have made their
empires out of. The nice thing with Google is, they are giving it back,
just doing so on their own terms. Given that they are not charging
anything for it, at least I can live with those terms. If I don't like
those terms, the original data, the one that Google took, are still
there for me to take.

I see absolutely no problem with this. If there is any, I would love to
be educated.
