I use geocorrelate-gui which is excellent. I leave my camera on winter
time and make a 10 hour adjustment in the GUI, then a few seconds change
after that as needed, in a separate box in the GUI.
Of course this person may not be using Linux and need some other program.

The Canon PowerShot camera series comes to mind. I have an S5IS, and play 
around a little with it, but haven't done any development work. With the 
CHDK (Canon Hacker's Development Kit) you can do all sorts of things 
inside the camera, such as run a script to detect motion, set 
speed/aperture outside the manufacturer's default ranges, and convert the 
USB input into a remote camera trigger.

I can conceive (although I haven't into it) that you might be able to 
insert a script that would accept GPS position data through the camera USB 
port, and write it in the EXIF data on each photo as it is taken.

It might be worth a look to anyone interested in this with the time to 
investigate. Check http://chdk.wikia.com/wiki/CHDK for more info.

I own a Nikon L19 (among others). I'm looking into ways to geotag its  
photos, and more for the challenge than anything else, am avoiding  
computer-based software, i.e. I'm looking for hardware solutions, ideally  
an integrated GPS logger and photo tagger. My research so far is on my  
blog .

BTW, I use Geosetter  and have been able to add  
various EXIF values including the date/time stamp and location to regular  
JPEGs, such as those taken by typical mobile phones.

Re: [OSM-talk] I ordered my first personal camera so I can do 'photomapping' or 'geotagging'

[Greg Troxel]

  Yesterday I ordered my first camera(Nikon Coolpix L19). Mostly with the
  purpose of taking photos while I have a gps along with me, to later
  geotag photos with josm and later use the pictures as sources for street
  names or Points of Interest.

  Does anyone have that camera? I was a bit unsure whether to buy it or if
  I should ask first here if anyone has it, but as I read it supports exif
  2.2 and memory cards(SD) I'm familiar with I decided to buy it without
  asking/mentioning first. Just wanted to share.

I don't have one, but I've looked at image files from a nikon s210,
which I'm sure has similar firmware.  So it's virtually certain that the
camera will be straightforwardly usable for creating geotagged phtotos.

My advice:

  set the camera clock in UTC (regardless of where you live; it's the
  One True Timezone :-)

  Before going out geotagging, set the clock, because if it's right you
  can either skip or have an easier time with the time sync issue.

  take a picture of the GPS receiver's time before and after your
  session (of course your GPS receiver should be set to display in UTC
  as well, but this is only for your benefit)

  figure out how to deal with timezones with your geotagging setup
  I would use exiftool calling it as "TZ=UTC exiftool "

  install exiftool and read the man page; it is set up to geotag the
  images from a gpx file.  Or you can use the builtin support in josm.

[OSM-talk] I ordered my first personal camera so I can do 'photomapping' or 'geotagging'

[Niklas Cholmkvist]

Hi,

I own a cell phone which can take pictures, but it doesn't store
pictures in exif format. After much research over time it seems I
couldn't even add exif by hand to the pictures I took with it.(with the
purpose to put the modification date in exif format in the picture by
hand)

Yesterday I ordered my first camera(Nikon Coolpix L19). Mostly with the
purpose of taking photos while I have a gps along with me, to later
geotag photos with josm and later use the pictures as sources for street
names or Points of Interest.

Does anyone have that camera? I was a bit unsure whether to buy it or if
I should ask first here if anyone has it, but as I read it supports exif
2.2 and memory cards(SD) I'm familiar with I decided to buy it without
asking/mentioning first. Just wanted to share.
