reverse geottaging?

[dltmdan]

Hi.

I wanted to create gpx file from my photos with gps information.
all of my photos are in the directory d:\photo

I copied exiftool to d:\photo directory and entered the phrase at dos prompt, win 7 32 bit as follow. 

d:\photo\exiftool -p gpx.fmt -d %Y-%m-%dT%H:%M:%SZ d:\photo> out.gpx

and I have an error message saying

"error opening directory >
file not found: out.gpx
1 directories scanned
15 image file read
1 file could not be read"

Could someone help me to figure this out?

I can't download your screen cap right now, but the only way this could happen at the cmd.exe prompt is if it isn't a normal ">" character.

But my guess is that the command wasn't run in cmd.exe, and that you used the GUI, which doesn't handle redirection with ">".

Also, in your output "gpx.fmt" is printed a number of times, so exiftool must not have been able to read the gpx.fmt file -- probably because it wasn't in the current working directory where exiftool was run.

Hi Phil,
Just to help...
From screenshot (taken with camera) I can see, that ExifTool is being used in console window (I'm not sure if it's Windows).
The screenshot doesn't contain actual command; just ending of result:

Code Select Expand

gpx.fmt
gpx.fmt
......
gpx.fmt
Error opening directory >
File not found: out.gpx
    1 directories scanned
   15 image files read
    1 image file could not be read


-that's all (no path/prompt at the end).

Hi Phil,

I ran the command from 'RUN" prompt.
So this time I tried cmd.exe.

It does generate out.gpx however it turns out that is not track record file.
It is the text file only with 'gpx.fmt' repeatedly typed. 

What did I  do wrong?
I am attaching captured image of the command prompt along with the text editor of out.gpx

Hi,

And you do have gpx.fmt file (from ExifTool full distribution package) in the same folder where exiftool.exe is?

[Phil Harvey]

Type the "pwd" command before running exiftool to see the current working directory.  If the gpx.fmt file isn't in this directory, then specify the directory on the command line with -p D:/SOME_DIR/gpx.fmt

My bad.. I have assumed gpx.fmt file should be where exiftool.exe is. Sorry for confusion...

Thanks Phil and Bogdan

Copying gpx.fmt to the picture directory solved all problem.
Thank you very much.

One more question.
Some of the photos lack gpstimedate tag.
How can I output gpx file in the order of  original date/time (not modified or created date)?

I tried
exiftool -fileOrder datetime -p gpx.fmt  d:\photos > out.gpx

but it does not seem to create chronological track.

[Phil Harvey]

The -fileorder option takes a tag name for an argument.  So I think you want

-fileorder datetimeoriginal

or

-fileorder gpsdatetime -fileorder datetimeoriginal

to sort on GPSDateTime, or DateTimeOriginal if GPSDateTime isn't available.

It works perfectly.
Thanks a lot for the help and your amazing software.
