Good Morning,

I am trying with no luck so far to form an exif string that will extract the Geotagged information from .jpg images (EXIF 2.2 Metadata).
hardware and software details are as follows:

1. Camera - is a Chicony 5MP module (CKAC520) integrated into the GETAC F110 ruggedised Tablet.
2. Software - GETAC Virtual-GPS in conjunction with GETAC Camera software.

The Geotagged information is being watermarked onto the Image so I know it is being recorded, however I ahve had no luck so far extracting it via exiftool.

Any assistance is appreciated. I have attached a sample for any testing you want to run.

All I could see in that file was

So something is stripping the metadata.

Phil Harvey

ExifTool reads metadata, and can not extract text rendered in the image itself.  In your file, there is no GPS metadata to read as Alan points out.

- Phil
...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Thank you alan & Phil,

I did manage to extract the same ammount of information as Alan but thought I was doing something wrong.

I had a hunch that the GPS metadata was not being encoded. The software manual for the camera and  GPS states

"Getac Camera is a geo-tagging camera program, which allows you to stamp geographical information on photos as watermarks and embed such information into JPEG files as EXIF 2.2 metadata"

I have managed to get the geotagging watermark function to work however as we have discovered the Metadata is not being recorded.
I have downloade the latest camera and GPS software so I hope that this will fix the issue.

I will post the results.

UPDATE,

Latest Driver and software for the GPS and camera now save the GPS info in Metadata.
