I put the latest available MAP module onto my test gallery, along with ~1000 raw images from my camera. Unfortunately the map module did not import any GPS information.
After a quick update to the exifer module, exif displays correctly for raw images.
I made a couple of quick tweaks to the map class, and now GPS data from raw images can be imported.
I can make this code available if you wish, however, it would make the module dependant on the exif module (didn't want to re-invent the wheel)
I can only test against Canon CR2 images, unless someone can provide new ones.
Why don't you go ahead and attach the patch to this feature. Making the map module use the EXIF module was a goal I had as well, but the original author of the EXIF import function said that he had problems with it importing from certain cameras. The EXIF library that's currently used in the map module apparently has better support, but I think it only supports JPG files. So, I can take a look at incorporating your patch sometime.
Sorry for the delay in responding. I suffered a corruption in my gallery install (was a debug system so not much of a problem). Anyway, wouldn't be right to upload a patch, no matter how trivial without checking that I cannot reproduce the problem. I believe that the problem was a hard disk error and that the machine crashed during a write.
There are two files. I updated the map module, and exif module to the latest available versions. Then applied these patches. I have uploaded >1000 images to the test server, and those which are tagged correctly display. However, these are tested against CR2 images only.
Both the exif module and map module need patching, separate files attached. The exif module has a patch released by the group, IF you can apply this then it will be sufficient. Unfortunately, the patch I had included a non-printable, non-writable character, which caused PHP header errors, so had to be reverted and applied in this way instead.
I have noticed that the position can be read on import either via web-browser, or local server (I prefer symlink but shouldn't make a difference).
I have not tested gallery-remote upload thoroughly (but again, should be no difference).
Going to edit photo, read exif from headers works, as does the maintenance mode read GPS data from headers.
Patch to allow map to drag exif data from raw, using exif module
Patch to exif version 1.2.5 to enable RAW formats
