<span class="gmail_quote"><br><br></span>Thanks for the reply.<br><br>Good news: I got my map returning the value of the pixel and then producing a plot based on the value. (I was finally able to find the php mapscript code for it... documentation for the organization of program files is quite lacking... perhaps I could help improve that somehow)..
<br><br>Anyone else have some ideas on how to hilight all the matching pixels? I think I've read that someone has been working on it, or I saw some hilight methods in the code somewhere. Ideas? Anyone?<br><br>Thanks for the help!

Hi Sam,<br><br>><br>><br>> What I need to do is first, be able to query the map to get the pixel<br>> value<br>> of the point clicked...<br><br>this should be already supported by query system.<br><br><br>
<br>

<br>but I've never finished due to other priorities.<br>If you're good with JS, php and Mapscript you can have a look to hilite<br>, wps, kaRouting tools. They use the same principle but they are not<br>simple scripts and there's no documentation. You'll need to do a good
<br>dive in the code.<br><br>ciao<br>Lorenzo<br>_______________________________________________<br>ka-Map-users mailing list<br><a href="mailto:ka-Map-users@lists.maptools.org" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
