I'm a little confused about what you say. Do you mean when i click one point , it's just ask for a query?<br><br>because i think query is just i type in some word, and then something happen to look up in some tables.
<br><br>I look through your suggestion and the URL you gave me , but found no example as i asked. <br><br>i think it's very popular application , maybe someone has realized before. I'm a beginner, so maybe i misunderstand what you say.

<br>ka-Map WIki:<br><br><a href="http://ka-map.ominiverdi.org/wiki/index.php/Query">http://ka-map.ominiverdi.org/wiki/index.php/Query</a><br><br>Basically speaking, you should redefine the myQuery function in the startUp.js
file<br>(either tools/kaExplorer or in the aqua UI).<br><br>Then, it is possible to use PostGIS functions to locate the point of the layer nearch<br>which the mouse was clicked.<br><br>With best regards,<br><br>Victor<br>
