How to extract GPS tags from a image

Hi all,

I think I have tried almost everything.

1. I have been able to do that from a .NET program and by using
PropertyItems. Unfortunately PropertyItems is not available in CF

2. Using OpenNetCF. The GPS tags are not defined in this library.

3. Using a C++ COM Class and calling that class from my CF program.
Based on this
http://www.pocketpcdn.com/articles/...=57&atb.set(a_id)=6211&atb.perform(details)=&
Unfortunately that function doesn't return the GPS tags either.

What else can I try? I'm really desperate with this.
Any help will be appreciated.

Thanks a lot.
 
Hi LEM,

I had the same problem as you: I needed to get the georeferencing data
of images - in particular case of GeoTiffs.
I wrote myself a C++ Wrapper DLL which holds references to the image
loaded via GDAL - which you can, with a bit of tweaking and searching
compile for WinCE. An advantage is that you can read a wide varity of
file types.

I hope this helps,

Cheers,
Tom
 
Hi Fabien,

I'm not sure if I understand you. What I need is to extract the EXIF
data associate with an image.

Fabien, I appreciate your help but in my first post I mentioned that
I used OpenNetCF but that doesn't return the GPS tags.
 
Do you need the EXIF Tags or sticking to a ready file format like
GeoTiff (which again would work with GDAL, s.o.)?
