I would like to use my iphone for navigation. I want to read GPS data (latitude and longitude) from iphone and save the data into my computer to use it for navigation.
I am using Matlab in my computer.
Any one can give suggestion/ solution?
So the tool I mentioned in my comment is called exiftool by Phil Harvey. I probably didn't think this through thoroughly because looking at your question, you didn't specify your data coming from photographs which is what I do with this. The data would be coming from iPhone photos. If you ARE taking photos with the phone, this solution may work for you.
Once I have a collection of photos, I use the following two batch scripts. The first script calls the other and passes in the photos.
The first script that you run runs the other script. so this code is in a file called "output_files.bat" and it runs the "run_tool.bat" script.
for %%a in (C:\path\to\photos\*.JPG) DO run_tool %%a
Here is the "run_tool.bat" file
echo %1 >> output2.txt exiftool -s3 -C "%%+.6f" "-EXIF:GPSLatitude" %1 >> output2.txt exiftool -s3 -C "-%%.6f" "-EXIF:GPSLongitude" %1 >> output2.txt REM Add a blank Line echo[ >> output2.txt
It creates an output file (output2.txt in this case) with the Latitude and Longitude for each photo.
