Your KML doesn't show up in FF2, I don't know why but the file http://www.charitywater.org/map/wells.kml fails validation in http://kmlvalidator.com/validate.htm > The goal here is to allow a user to search and locate a project based > on it's GPS coordinates.

It's unlikely that any given set of coordinates will be an exact match. Even a GPS unit will give different readings from day to day. So you're going to have to search within some tolerance i.e. find nearby targets. You might find that the use of KML will hamper this. Using GGeoXml to render the KML en-bloc makes it difficult to get hold of the individual marker information to do any comparisons. The usual way to tackle this kind of requirement is to maintain a server side database, and have the webpage submit search criteria and receive in return data to display on the map - example http://code.google.com/apis/maps/articles/phpsqlsearch.html If you're stuck with using a spreadsheet, I guess its not easy to implement on demand searches in that. So you'd need to implement it client side - obtain the data for all of your markers, and iterate through them comparing to your target search data, displaying the nearest one found. It's not that difficult but not trivial. How about an alternative approach - just centre the map on the 'search' coordinates at a sensible zoom level and allow the end user to see what's nearby for themselves. You could add a circle to show a 10km radius or whatever. -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
