[mapserver-users] How to query attributes via WMS

[Bruce Cheney]

Steve,
 
I believe I misunderstood what you are doing. Maybe a slight
clarification would be helpful.  I see three different options:
 
1.  Create a Mapserver WMS that feeds into the Google Maps API (Google
API controls display)  = allowed
2.  Use Google Maps as a WMS to feed into Mapserver on the server side
(Mapserver API controls display) = not allowed
3.  Use Google Maps to mesh with Mapserver data on client side (example:
Open layers meshes two on client side - Openlayers controls) = allowed

 
If I understand you correctly you are using #1 where Google Maps is the
controlling environment.
I thought you were implementing #2.  
 
For a MapServer discussion reference on this not being allowed see:

<BLOCKED::http://www.nabble.com/Google-Summer-of-Code-Ideas-td9378841.ht
ml#a9399538>    Refer to Jan and Daniel's comments.
 
Obviously this is not an official statement.  Maybe someone has an
official statement from Google that they could post?

Bruce -

 

I don't see anything in Google's T&Cs that disallow adding layered tiles
over their own. In fact since the API has a class called
GTileLayerOverlay it looks like they are encouraging it.

I am not answering your question - sorry.  Instead I have questions for
you.  Will Google allow using their maps as a WMS?  Did you get special
permission for this?  Everything I have read says this is not allowed
from the Google side. I am asking because we would really like to use
Google as a background for our web app also and if this is a new
development then we would be interested in doing it also. Thanks.

I'm using mapserver to overlay png tiles over a google maps interface
and it's working well. I have a series of shp files on the server and I
want to build a search interface so the user can query the actual data.
An example would be in simple terms: 'select all data from shp where
layer = 'thislayer' and field like '%castle%''.

 

Is it possible to interpret a variable if I sent it via the Url with the
WMS call? For example, I'll tag on &TestVar=castle to the WMS call. Can
the map file be set up to interpret TestVar and perform a query against
a shp file field in a given layer?

 

Thanks,

 

Steve
