Not necessarily a database, but you have to store the data somewhere. An example of reading marker data from a text file - http://econym.org.uk/gmap/basic9.htm > i read many codes but i can't save the markers That would depend on where you want to save them 'from'. Guessing it's a webpage, the difficulty is that its practically impossible to create or edit files from javascript. Good, I don't want other peoples webpages altering files on my computer. So the usual technique is for javascript to pass the data to some server-side application, which will do the actual saving to ... the file or database of your choice. http://groups-beta.google.com/group/Google-Maps-API/web/using-databases-with-gmaps-apps --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
