How do you "Geotag"?.

Just curious really have no real use for it but just wondered how you get the information from a picture?.
Do you require a certain software download?.
Usually on the images EXIF data, Saved image, right click, properties and details tab.Do you require a certain software download?.

There are a couple of ways to get the location in to the image data. One is to attach a specialised GPS unit to your camera. This will record the info at the time of taking the picture.
The other way is if you already have a general purpose GPS. You can download the track data to your PC, and using software that is freely available from the net, embed the information to your photo data. For this to work, it is important to make sure that your camera and GPS clocks are synchronised, as the software works by comparing the time on the image to where you were at the same time on the GPS data log.

That actually sounds like a very clever idea. Does it work as smoothly as it sounds or is that the simplified version? And do you know if any of the major phone OS' (Android or Apple essentially) do an app that would store the GPS data in the correct way?The other way is if you already have a general purpose GPS.

My new camera has a geotagging option built in. But I'm not sure what the point is. I know I can "right click" the image and it will give me lat/long... but what's teh point? I want to have a map with my photos overlayed or somethign. What can I use for that?
I like being able to show exactly where a shot was taken. And I sometimes use Google Maps/Streetview to have a nosy at an area. Geotagged photo's show up on the map (if you 'grab' the little man you'll see dots you can place him on) and that helped me decide to go when I was last in the Lake District - a lot of the photo's showed just how impressive the Langdale Valley is. Maybe a niche use but a nice touch nonetheless.I geotag all my photos with an Amod GPS logger and HaudohGPS on the Mac which is a brilliant bit of software. The latest version will map your photos as well as embedding the location within the exif data on the shot.
Practically it means when I upload a shot to flickr I don't have to add it to the map manually, flickr reads the location from the exif data.

As said, the GPS info can be embedded in the exif data.
I use an AMOD gps logger and HoudahGeo to tag my pics, works a treat.
Sounds interesting, I'll have a look into these.I use an AMOD gps logger and HoudahGeo to tag my pics, works a treat.
Do you just leave the logger in your bag when you are out and about, I'm guessing you don't have to do much else with it other than sync the clocks?
Pretty much that, even easier I've got my Macbook Pro syncing its clock with a time server and my bodies set to update to computer time through Eos Utility so every now and again I just plug them into the Mac and sync their clocks.
The logger itself is only about the size of a box of matches and I've put it on a karabiner, it either hangs off my camera bag or off the epaulette of my gitzo coat if I'm not carrying a bag and just does its thing.
The AMOD is driverless, when you connect it with a mini USB it appears as a drive with one folder, in that folder is just a list of log files, I drag them across to a folder on my Mac.
HoudahGPS is clever enough that if you can't remember which log file you need for an image you can select all and it will find the corresponding log for the image. It will also write xmp files, or embed the location in the exif.

I think Picasa has a map mode that uses EXIF geotags. Apple's iPhoto and Aperture certainly do (the latter actually has some very nice functionality around this). Flickr also do, although the default setting is for uploaded pics to not be put on your map - need to change in Your Account > Privacy and Permissions > Import EXIF location data.
I took a Qstarz GPS logger with me on a long trip - I found it tracked fine just inside one of the top pockets on my daypack, no need for it to be hanging outside. The other nice thing is that is uses a standard Nokia battery so easy to get a spare including higher capacity ones. Other than that, I just charged it overnight, switch on in the morning and forgot about it. Battery lasted about 36 hours at a time, and it stored a few weeks of data even logging all day. The software that came with it is awful but Houdah and others support getting the data from the device, once you've got a GPX that can be fed into Aperture or something else to tag them properly.
I'm looking forward to more cameras supporting this stuff natively, I really like having map-type views of photos, and if I can have the camera do it without hammering battery life it would be a very good thing.

There are loads of phone apps that can create the track logs you need to geotag images.
It's easier if you pick one that will output a gpx file for you, although there are numerous file converters if you find an app you prefer which uses a different format for the log file.
Again, plenty of free software for doing the actual "tagging" bit.
There are even websites where you can upload the gpx file and your images, the website then tags the images for you.
One such is http://www.gobreadcrumbs.com/ , which also does some other neat stuff with gpx logs.
