Ciao Benedetto, I used the same approach with an application written in java in the AppEngine. In that case I have a JSP page which outputs the KML (actually KMZ) dinamically. You should be able to do the same in any other language (PHP, phyton, cgi): produce the KML in memory and write it to output. Pay attention to: - declare the correct Mime type - the number of features must be less then 10000 - the size of the KML content must be less then 10 Mb
Hope it helps, Davide PS Have you considered usign FusionTables layer? They are quite powerful for filtering data dynamically. 2010/6/9 benedetto.bozano <[email protected]> > Hi all, > > I have a database containing several paths, each with its lat/long > points.
