I'll make this a feature request, sure. I know it's possible to read the 
location
from the EXIF header of a geo-located image. I would also have to extend Geo 
Mashup a
bit to be able to add located attachments to a map.

Hi dylan

This would be the 'icing on the cake'. 
I tested mobypicture.com (iframe with shortcode in wordpress - but photos are 
linked 
back to mobypictures...) before I found geo-mashup and this would be a great 
extension to the already 'formidable' plugin.

Look forward to it with anticipation and thanks.

this feature would be great! specialy when it would work with images uploaded 
through
NNGallery too.

any updates for this function ?

No progress yet, though I have one client with some interest in it. I'll post 
any advances when they are made.

This would be great!

I have a ton of images with EXIF geo tagged coordinates.

Does geo mashup only accept decimal geo tag format, or can it use the EXIF 
format too ?

I found at least that I can export the EXIF geo tags in decimal using exiftool 
like this:

exiftool -csv -gpslatitude# -gpslongitude# *.jpg>out.csv

however this sometimes produces decimal values with greater than 7 digits after 
the decimal point. eg -23.61133,-46.6748366666667

Does Geo Mashup accept such long numbers or must I truncate them ?

Geo Mashup will accept more digits after the decimal, but they'll be truncated 
internally.

Has there been any progress on this issue?  I've been looking for a plugin that 
will let me create a global map of all geo-located images on my site, ideally 
with a link in the info box to link back to the original post.  Is this a 
possibility using geo mashup?  If not, is there any modification I can make to 
accomplish what I want?  Thank you very much!

I haven't been able to implement this yet, but I'd still be very open to 
contributions.

As before, I'm exporting the geo-tagged data from the image and then importing 
that data into the db using a custom import/export tool. It's not a very clean 
way of doing it, but it works.

I did see there was a wp plugin for EXIF data on import but any such plugin 
would presumably need to be customised to make it place the geo-data in the 
geomashup table.

If another plugin supports http://codex.wordpress.org/Geodata, the "Copy 
Geodata Meta Fields" setting would take care of adding it to geo mashup.

Err, but wouldn't that mean you end up having a duplication of geo data ?
