ReportedBy: wol...@si... QAContact: gst...@li... GNOME version: Unversioned Enhancement GNOME milestone: Unspecified It would be nice to provide the ability of storing geotags inside multimedia files. Of course some research would be necessary about which data is stored and in what format. The documentation about how the EXIF standard does this can be found under http://www.exif.org/specifications.html (specification 2.2, page 52) or http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/GPS.html -- See http://bugzilla.gnome.org/page.cgi?id=email.html for more info about why you received this email, why you can't respond via email, how to stop receiving emails (or reduce the number you receive), and how to contact someone if you are having problems with the system.

Currently, I don't really see the point though, since we don't support EXIF tags yet (AFAIK), and that's probably the main use case. -- See http://bugzilla.gnome.org/page.cgi?id=email.html for more info about why you received this email, why you can't respond via email, how to stop receiving emails (or reduce the number you receive), and how to contact someone if you are having problems with the system.

Actually, this idea is not intended to set EXIF tags, sorry for my unclear bug report. It is intended to store geotags in other file types like vorbis or speex. The EXIF specification is just there for information about how others store the tags. If I currently want to store geotags in an ogg/vorbis file, I can only store them inside the 'comment' field, but that means that the comment field is reserved for my geotags and cannot be used for anything else. Vorbis supports free-text tags, and I bet most other file formats do too, but I cannot set them using the TagSetter. That was the idea behind my feature request. -- See http://bugzilla.gnome.org/page.cgi?id=email.html for more info about why you received this email, why you can't respond via email, how to stop receiving emails (or reduce the number you receive), and how to contact someone if you are having problems with the system.

In addition to EXIF and XMP that has some tags related to GPS, there might be some other formats or individual applications interested in GPS tags. Follow bellow my suggestion for those tags: GST_TAG_GPS_LATITUDE G_TYPE_STRING "DDD,MM,SSk" fixed size string where: D- degrees, M- minutes, S-seconds, k- N (north) or S (south) GST_TAG_GPS_LONGITUDE "DDD,MM,SSk" fixed size string where: D- degrees, M- minutes, S-seconds, k- E (east) or W (west) GST_TAG_GPS_ALTITUDE G_TYPE_FLOAT (negative mean bellow sea level) GST_TAG_GPS_SATELLITES G_TYPE_STRING (This tag can be used to describe the number of satellites, their ID number, angle of elevation, azimuth, SNR and other information in ASCII notation) GST_TAG_GPS_MEASUREMODE G_TYPE_INT (2 or 3 dimensional) GST_TAG_GPS_DOP G_TYPE_FLOAT (data degree of precision, HDOP for 2-dimensional, PDOP for 3-dimensional) GST_TAG_GPS_SPEED G_TYPE_FLOAT (always in km/h) GST_TAG_GPS_TRACK G_TYPE_STRING "xxx.xxkyyy.yy" fixed size string where: xxx.xx from 000.00 to 359.99 yyy.yy from 000.00 to 180.00 (vertical from down to up) -01.00 for unknown direction k - 'T' true direction k - 'M' magnetic direction This value means the direction of movement. GST_TAG_GPS_IMAGE_DIRECTION same type as GST_TAG_GPS_TRACK this value means the direction of image (captured, or on user hands) GST_TAG_GPS_PROCESSINGMETHOD GST_TYPE_STRING (method used for location finding) GST_TAG_GPS_AREAINFORMATION GST_TYPE_STRING (name of the GPS area) GST_TAG_GPS_DIFFERENTIAL G_TYPE_BOOLEAN (if using measurement with differential correction) I think those fields are good for the time being (I have proposed them by looking at Exif and XMP, except for vertical direction with was by myself).

Its also sufficient for EXIF [1][2] [1] http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/GPS.html [2] http://www.exif.org/Exif2-2.PDF Instead of GST_TAG_GPS_AREAINFORMATION we could have GST_TAG_GPS_LOCATION (see Bug #548652).
