I have used GPS on my camera since the Nikon D1 allowed it.

GPS is now well supported on Nikon cameras.
There are dedicated Nikon GPS units that work well and these populate the EXIF data fields so you can see where your pictures were taken.


I actually have used the Custom Idea GPS unit since 2007.  It is very small well featured and cheap.
See here.  Custom Idea GPS unit

Whilst I am sure that having GPS data in the EXIF of images is useful, I do rather draw the line at carrying more GPS devices than a modern airliner.

What would be useful to me would be a means of using the GPS data from my iPhone with my camera.

I think you will find you can use GPS data from an iPhone with your images.

All images are time stamped. All GPS data is time stamped. Putting the two together gives you a GPS location for the image. (Mind you, the camera clock needs to be right!).

There are several applications which combine the two, including Lightroom I believe. Just how you extract the GPS Data from the iPhone I don't know but given the number of 'apps' available for the iPhone there must be some that will do it.

I bet Doug will know of one.

That is possible but you need to be able to know that the time on the iphone and camera match. I dont know if you can get track data from the iphone or ide.nify later when you were where.
My iphone is an iphone 3G so I haveblocation services but no compass or other.
The GPS that I use is only anout the same size as 1/8 of an iphone.

You are both right but the GPS data is time stamped with much greater accuracy than is the EXIF and if the camera clock is out they won't align.

I was thinking more of a cable from the iPhone to the camera to allow a GPS entry into the EXIF of the images. I don't think the iPhone outputs NMEA data so it probably isn't possible.

That sounds like something I will have to investigate.
I'm sure that this should be possible but you might need an applet on the iphone to do this.

I will have a search.

Well here we go.
Since Geoff is a fellow Mac user I will target the responses more directly towards Mac.

How to get GPS data from iphone into Aperture.
http://documentation.apple.com/en/aperture/usermanual/index.html#chapter=13%26section=4%26tasks=true

http://documentation.apple.com/en/aperture/usermanual/index.html#chapter=13%26section=4%26hash=apple_ref:doc:uid:Aperture-UserManual-91292PLC-SW9

Note that for iphones if you have 'location services' on then automatically the GPS data will be put into the image EXIF. That means if you take a picture with your camera and a similar one with the iphone then you can just copy the GPS data from iphone image to main camera image.

To get photos from the iphone to PC is simple using iTune or iPhoto, Aperture, etc.. using the standard USB cable.

If you dont want to take a picture on your iphone at the same time you can however use this app and it will give you your current location which you can save or write down and input later.

Just to make yourself a little paranoid then see here.

Useful sometimes but then again big brother can be watching you also!!

It won't matter to even one minute unless you are in a car taking images at speed. If you are just walking about it will be right to within a yard or two.

There are several applications which do this I know.

When I am using several bodies I just dump all the images in one folder, they are sorted by time and usually come up in the right sequence.

I have all my bodies synchronised to within a second. That's near enough.

Yes indeed Robert.
I used to do this with a Windows PC program called OziExplorer which used a GPS track and the times from that track were matched with the image date/time created.
They matched very well unless you were traveling at speed.
