I just got back from a trip to Manas & Kaziranga National Parks. One of the things I wanted to try was “Geotagging“. Geotagging helps to write the exact location where the pic was shot, into the EXIF of the pic itself. The software also creates a “.kml” file which will help view the route along with, the exact point on the track where the particular photograph was taken.
I took along a Garmin Etrex Legend GPS and also this is where it gets more interesting, a Nokia 5800 Expressmusic along with a Nokia LD-4W bluetooth GPS. Although the Nokia 5800 Expressmusic has a built in GPS, I took along an external GPS since that is so much more flexible for my application. Besides, the Nokia LD-4W is only a few tens of grams in weight and, smaller than a credit card 
. So its hardly any trouble carrying it.
I set the Garmin to “Log Track mode”. For the Nokia, here is what I did. Since the Nokia application, “Sportstracker” was at that time not available for the Nokia 5800 (Sportstracker for 5800 EM) , I downloaded another software called @Trip v1.01 . This is a simple phone app that creates a log of the GPS track and writes to a file. You can also use similar apps like GPSED. It will also geotag pics clicked by that phone. Besides you can use the bluetooth GPS + gps app on any non-gps phone.
