Check out this cool site (Panorama Explorer) which is based on Google Map API. It's a photo sharing site which allows you to tag your photos on a Google Map. It also can place photos on the correct location if GPS track data (GPX format) is provided. At the moment there are few digital cameras w. built in GPS receivers that offer the ability to store GPS data in the EXIF header. But there is a workaround - just synchronize the GPS receiver time w. your digital camera clock. Or you can calculate the time offset and get the appropriate track record to retrieve the coordinates (long/lat). Exactly that does Panorama Explorer !
