Geotagging? Is that some sort of wrestling manoeuvre?

Sadly, no. It’s adding geographical data to files, which is especially handy for images.

What witchcraft is this?

It’s pretty simple, really. Pro photographers used to carry an external GPS unit and marry up the co-ordinates with the time-stamp on their pics. But more devices such as mobiles and cams are coming with built-in GPS, meaning that your images or film already come geotagged.

Nice! Why do I want this?

Well, you can add your pics to various websites or online maps. Create pictorial maps of wildlife sightings, hiking trips or just to add that extra layer of smugness to your travel blog in order to annoy friends and family.

Right-o. Where can I find this?

Well, the Ricoh 500SE and GE E1050 cams both come packing geotagging as standard, while the Nokia N82 and N78 have also been born with the geotagging gene. Sony has a separate GPS-CS1 GPS receiver that can be used with Alpha DSLR and newer Cyber-shot ranges.

OK, I’m fully geotagged up. What do I do now?

Upload and share you dolt! Google's Picasa and Flickr Map both let you upload geotagged pics and add them to maps.

There’s also a few Flickr/Google Earth mashups like Geo Photos that will deliver a live feed of any geotagged Flickr pics in Google Earth. And you can now even geotag YouTube vids and plonk them straight into Google Earth. Sweet.

Cool – one last question… where am I?
