Title: Feature Request - GPS/IMU data format - POS
Post by: Rob_Aus on June 28, 2019, 01:39:23 AM
Hi,

I have some IMU data exported as POS file format. Is it possible to have exiftool able to support this file format for geotagging images with.

This is what the POS file data looks like

TimeOfDay(UTC) PosLat(deg) PosLon(deg) PosHeight(m) AngleRoll(deg) AnglePitch(deg) Heading(deg)

The POS file is exported with RTK corrected coordinates, and we wish to be able to override
existing SPS coordinates in an image with more accurate ones.

Alternatively we are able to export as CSV, which looks like this

Is there anyway to use the above file formates for geotagging?

Thanks

Hi Rob,

Could you attach a full POS file to your post?  I want to see the exact formatting and file name.  It should be easy to add support for this format.

No.  Wait.  There is no date in the POS file (only a time of day).  But there is a date in the CSV.  But the CSV is missing the orientation angles.  Is there a format where all information is output?

Hi Phil, thanks for the reply

Sure, we can choose the outputs for the CSV

Attached is one with the date/time/position/angles

Thanks

OK, thanks.  I'll add support for this in the next release.

ExifTool 11.54 is now available, and you should be able to geotag from the CSV file you sent with this version.

ExifTool should be flexible about the information included in the CSV file, and you will be able to geotag from any CSV as long as it can recognize date/time and lat/lon headings somewhere in the first line of the file, and provided the date formatting is "DD/MM/YYYY".
