Bug#385488: ITP: gpscorrelate -- correlates digital camera photos with GPS data filling EXIF fields
Stefano -
Looks very close to a program I started writing at one point :-)
The only changes I would suggest to the description are here:
granularity) the photo as been taken, the GPS data are stored unmodified
^^ has ^
A few things I'd suggest:
- There are times I am taking pictures intermittently and would
rather run my GPS receiver only at those times (say, at each scenic
overlook along the highway). In that case I would like the program
to compare the times on the preceding and following track points.
If they differ by less than T, then interpolate. If they differ by
more than T, then use the location for the track point that is
nearer in time. I should be able to set T in either a
configuration file or on the command line.
- The GPS can report time in UTC, but the camera may be set to local
time. The user should be able to specify what time zone the camera
is set for, or to ask the program to guess the zone based on the
longitude. (Admittedly the EXIF time can be adjusted using jhead.)
- I would like the option to store the location as a JPEG comment in
addition to the EXIF header. Some viewers can show only the
former. I seem to remember a web site that expected geotagging in
the form of JPEG comments, but now I can't find it.

Description : correlates digital photos with GPS data filling EXIF fields
gpscorrelate fills EXIF (Exchangeable Image File Format) fields of
digital photos related to GPS (Global Positioning System) information
(e.g.: GPSLatitude, GPSLongitude, GPSAltitude, ...). The act of filling
those field is referred to as "correlation".
.
Inputs of the correlation process are a set of JPEG images and GPS data
encoded in GPX (GPS Exchange Format) format.
.
If GPS data are available for the precise moment (with a 1 second
granularity) the photo as been taken the GPS data are stored unmodified
in EXIF fields. If they are not, linear interpolation of GPS data
available for moments before and after the photo has been taken can be
used.
.
Both a command line tool (gpscorrelate) and a GTK+ graphical user
interface for it (gpscorrelate-gui) are provided.
Review of the above descriptions by some native english speaker would be
greatly appreciated :-)
Cheers.
