which Geo Information can be encoded in Exif and/or XMP

[calestyo]

Hi.

Maybe these questions are stupid and/or obvious, so please bear with me

1) What I want is, adding several kinds of metadata to my RAW (ORF) images.
Generally I do not wish to modify a RAW image, even not the metadata, so I'd like to simply put all my additions/modifications in an XMP sidecar file (of course this only works if the programs I use later on support these sidecar files, and if the let them override the image metadata itself).
Can I put/map all the Exif/tiff/EP/etc. tags also in XMP and is this than valid by the standards?

2) The main thing I'd like to add/modify as described in (1) are, apart from some general things like ImageDescription, TimeZone, Copyright, Geo Information.
I had a look at http://www.exiftool.org/TagNames/GPS.html .... but I'm not an expert and some I don't understand some of the tags.
I have a Solmeta Geotagger Pro[0], which gives some NMEA output, logging the usual suspects (GPS time, long, lat) but also compass direction as well as gradient and pitch.
Can all these be encoded in Exif? I'm especially not sure about the compass direction, gradient and pitch (whether there are tags for this at all).
Best would be if there was some tool that takes an NMEA file, reads as much information as possible from it and encodes as much as possible.


Thanks,
Chris.

Hi Chris,

Yes, this can be done.

Take a look at the Metadata Sidecar Files page.

And how about the NMEA->GPS encoding stuff?

See the Geotagging page for help with this.
