Bits n Bytes - GeoTagging snaps

Now you could GeoTag your snaps on Flickr or even use some 3rd party tools for doing it and then upload the map onto your Flickr profile. By Geotagging your snaps it gives more semantic sense to the snaps and would also help other viewers to know the place you have taken it.

Here is a quick explanation on how to do it. And this is how my Flickr map looks like

I remember having read (in some research paper talking about semantics in Image retrieval), that the new generation digital cameras would be having a GPS tracker built into them which would automatically tag the snap you have taken with its geographical coordinates. This geographical data would be encoded along with the other EXIF data of the snap. This simple act would be a big blessing for those researchers developing algorithms for implementing semantics in image retrieval engines/tools. By just knowing the location details of a snap one can extract a fair amount of relevant semantic information from the picture/photo.
