[Geodata] [Fwd: Fwd: [UMN_MAPSERVER-USERS] Google Maps as Mapserver Layer]

[Chris Holmes]

We have extra space on some of the SD state computers, don't we?

It seems like a cool thing to do would be to offer TileCache services to 
people.  They already have some WMS access.  It's nice, but super slow, 
and they'd like it to go faster.  We stick TileCache in front of it and 
let it iteratively cache, and those tiles in turn are made more public 
to all.

Thanks for the quick responses, that's what I was afraid of.  Fortunately,
for the State of Arkansas we have an online clearinghouse for all our
publicly available data (www.geostor.arkansas.gov
<http://www.geostor.arkansas.gov>) so the data is freely
available with or without Google's 'semi-free' services.  And the imagery
I'm wanting is running as a WMS service through ArcIMS WMS connector.  So
currently I'm using a Mapserver WMS layer to display the imagery.  It's
just frustrating when Mapserver displays the rest of the data so quickly
and
then takes so long to display the WMS layer through ArcIMS.  Guess we'll
have to bite the bullet and add disk space and serve it locally. At least
for my non-OpenLayers sites.  BTW...OpenLayers does display Google Maps
layers.  And it also allows you to define multiple connection url's
(www.domain.com <http://www.domain.com>, sub1.domain.com
<http://sub1.domain.com>, sub2.domain.com <http://sub2.domain.com>) for
your WMS layers which
increases the tile loading speed 5X.     Thanks again for the help.

Richie,

One of the quiet tragedies of the Google Earth/Maps mania is that once
public data is handed over to the Googleplex it becomes slightly less
public. You are only allowed to access mapping data served by Google via
Google-approved mechanisms, such as the Maps API or directly via Earth.

Another public geodata issue, I suppose. If enough folks who wanted to
"give their data to google" instead gave it to a 3rd party who processed
it into standardized tiles, then people could still get direct access to
the public data, and Google/Microsoft could easily integrate it as well.
