I have a map file which has some layers. The layers data is read from a postgis db extention. I have some linestrings which are read from a database with, <br>DATA "geometry from schnittverlauf"<br>and viewed in the rosa applet.<br><br>What I want to do is, I want to dynamically filter the geometries read from the database as per the users input, since I don't want every linestring to be drawn. <br>Can anyone tell me how I can do that? <br>Thank you all<br><br>Baris<br></div></body></html>
