Does anybody know a method to Geotag Olympus Raw files?

I have seen some GPS devices with software to add the co-ordinates to jpeg image exif information but I haven't seen one that works with Olympus Raw format, is there a solution out here?

I don't know re software and the ORF files, but isn't that a strange thing to do anyway ?

I always consider RAW files as "inviolate" and use an image management system to hold the metadata outside the files.

Here's a post on another forum I inhabit from that software on the topic of Geotagging and ORF that may be of interest.

You can still include various meta data in the EXIF region of ORF files. When I view them in Bridge I always add copyright and my email address. The image data is not affected and remains inviolate.

hi Jim

I agree in theory, but I've read a lot on a number of forums on how much software has not implemented the EXIF standard well (standard may be a stong name for something not maintained very formally ) and leads to problems.

This is also compounded in this particular request because Oly don't publish any documented standards for working with ORF files and therefore most of the software out there (even some big names) relies on 3rd party libraries that are developed by reverse engineering ORF into something useable by the various software developers so e.g. If Oly move the EXIF information around in their format or change the way that they present it in some way then the software developers have to start again.

Like You I write EXIF information into my files, but NEVER my RAW's

In the end of course each to their own and if Invicta wants to then he will find a number of hopefully useful discussions on geotagging software over in the Imatch forum

Thanks for the link. alas the software described in the thread does not support ORF format :(

It's possible that DNG files are supported, but I couldn't see any mention of this on the Robogeo site.

DNG files are so far the nearest that we have to a RAW standard, and there's the free converter DNG_Camera_Raw to convert from ORFs.

Just found it - DNG files _are_ supported:

http://robogeo.com/home/system.asp

So you can convert ORFs to DNGs (I do so as a matter of course) and embed the GPS data in the DNG. If you simply _have_ to keep the ORFs you can embed them in the DNGs, but I don't bother.

I might give Robogeo a try myself.

Good to hear you have found a solution that works for you.

I know it's an old debate (ORF vs DNG) and one that people are passionate about, but if you're happy to do away with the raw files then my concerns above are not so relevant.

This thread did interest me as I'm a techie geek, so I did do some digging and found a number of programs that claim to write the data stright into your files for you

http://www.geosetter.de/en/
http://geotag.sourceforge.net/?q=node/14

The former has the benefit of being based on the very reliable and widely used ExifTool so should have some stability

The latter has some useful features in that you can put the data into XMP sidecar files which can be read into DAM software if you ever decide to go that way. I also like the reverse lookup service they offer.

What format of ORF, neither say and as Oly keep changing them in un-publically documented ways the usual caveats have to apply.

p.s. Let us know how it goes as I think there will be other members interested.

I'm still going to keep my location information in a database because I understand databases better than RAW file formats and can debug them when I get it wrong .. IMatch for me

Why not just do a quick shot of the GPS display?

You don't have to discard the ORFs, there's an option to embed them unaltered in the DNGs. Obviously they take up more room then, but with external 500Gig drives costing 61 quid including VAT ( http://tinyurl.com/3s7m7t), file size is of little consequence these days.
