I'd like to create a KML file which lists all the LPG/autogas fueling stations in Germany. I do have access to a database which is daily updated with added/removed gas stations and also with current prices. As this database changes very often and is rather big (~1500 places in Germany alone right now), I'd rather not update a KML/KMZ file here every day. I'd rather have it so, that Google Earth automatically fetches the most current data from my server. Much like it's done with the "Google Earth Community" layer. How can this be done? Thanks a lot, Alexander Post Extras:       Valery35 Master Craftsman Reged: 09/02/05 Posts: 2269 Loc: Russia, Perm, Sun Re: Howto create a dynmaic data layer?

Create Network link, open Property and paste into string Link path to base kmz file ("http://mysite/myfile.kmz") 3. If base kmz file large, you can place this as distribute KMZ ("http://mysite/myfile1.kmz", "http://mysite/myfile2.kmz"...) and make folder with need count of network links Myfile (folder) -NL1 (to "http://mysite/myfile1.kmz") -NL2 (to "http://mysite/myfile2.kmz") ... Also can see my flash animations "Step 3. My first network link". http://www.mi-perm.ru/gis/earth/present/step3.htm Example (and history) of large NL see http://bbs.keyhole.com/ubb/showflat.php/Cat/0/Number/220598 Regards! -------------------- Applications | Blog | Geoblog(ru) | Spreadsheets | Photos | Pict'Earth | Eastgeology (ru) Edited by Valery35 (08/18/06 04:39 PM) Post Extras:       A_Skwar Tourist Reged: 06/13/06 Posts: 6 Loc: Wuppertal, Germany Re: Howto create a dynmaic data layer?
