Well, there are a few reasons why using MapServer is out of the question. 1. I
am running my mapping application on some server space that I have on the
computer science servers here on campus. Although I am granted server space, I
obviously have no ability to change the settings to Apache or put MapServer
into the cgi-bin of Apache. Therefore, although I can run PHP scripts (which I
do), running something like MapServer is out of the question. 2. I am running
Apache on my personal machine....and so of course I could install MapServer on
here, but my personal machine is not the "production environment"...it is
simply the testing environment. The production environment is my server space
on the CS servers - and if I can't run MapServer on those servers, there is no
point running it on my test server (my personal computer). 3. Even if I did
have access to a production server where I could configure Apache how I wanted
it to be - I am completely unfamiliar with MapServer and WMS requests -
although I am very familiar with HTTP requests and networking in general. WMS
is simply a protocol I don't know. In addition, I don't know how to create a
map that would work with MapServer. Consequently: I am currently using the free
map available at: http://labs.metacarta.com/wms/vmap0? Which is also used in
many of the OpenLayers demos. I am thinking, however, of using Google Maps
possibly, but I am not sure yet. So this is my dilemma: Under these
circumstances, how can I recognize which country a user has clicked on the map?
Several months ago at work I made a simple mapping application in Flash (at
which time I didn't even know OpenLayers or MapServer existed). For that
mapping application we simply overlayed an image of each country on top of
itself on the world map, and then the overlayed image acted as a button - thus
making it quite simple to tell which country had been clicked. I was hoping to
do something similar with OpenLayers in this mapping application that I am
currently building, but using the "Features" in OpenLayers to create polygons
that I could overlay over each country - and essentially have each polygon act
as a button so I could tell which country had been clicked. I noticed however,
that if I held my mouse button down on one of these polygons, I could no longer
pan around the map...which is definitely a problem. How does the example map at
http://world.freemap.in/ accomplish this task? I looked at the code, and
although I am new to OpenLayers and this whole WMS thing...it seems like it is
making some WMS requests to a MapServer server. Thanks for any help. David>
