[Chameleon] Problem with the Gazetteer Service

[Kralidis,Tom [Burlington]]

Yiasou Athanasis,

In trying your sample, I get results back.  Try "M6M" for the Postal
Code search, or "01" for the Watershed search.

1./ The functionality of the Locate widget is to use common geocoding
services (gazetteer, etc.) to acquire x/y points and navigate or plot
them on a map.

The geocoding services included in chameleon are specific to Canadian
placenames, postal codes, etc.  This is why you won't find any results
in your map, which is focused on Lesvos.

2./ To change the functionality of the services behind the Locate widget
(I've done this), your best bet is to:

A./ check out widgets/Locate/Locate.phtml which is the popup PHP script
B./ check out /htdocs/common/phpgeocoder/services, where there are a few
scripts which Locate.phtml calls
C./ add your own script to connect to one of your own geocoding
services/tools

That's the basic approach.  Some of the chameleon gurus may have advice
also on how to do this.

Cheers

..Tom

                Hello Chameleons,
        
        I am facing some trouble with the  gazetteer Service of
Chameleon.
        Independently of what I put in the text fields of "Place or
Feature", "Postal Code", "NTS Map Sheet" and "Watershed", no results are
returned! ("No Results Found"). You can check it out in
http://195.251.137.181/chameleon/samples/sample_bilingual.phtml
        

        1.                      What exactly is the functionality of the
button "Locate Place" as well as the other buttons like "Locate
Code/NTS/Watershed"of the Gazetteer? Why does it return places when the
gazetteer is appied with the demo map (chameleon.map) but NOT with my
map?
        2.                      How can I change the functionality of
the Gazetteer, in order to add my own queries?

        
        Thank you in advance!
