LadyBug can add geotag in to project by connect GNSS with computer. Only NMEA data format from GNSS LadyBug accept. When export panoramic image they are two way, One you can use “LadybugCap” and Two use “LadybugPro” software. Both Software can export panoramic image and you can see coordinate when it display but if you want to add geotag in to panoramic jpeg you should to use “LadybugPro”. I tried to export some of panoramic images from same project with both software and here is result when use Gdalinfo to see image infomation “Cap” is panoramic image from LadybugCap software and “Pro” is panoramic image from LadybugPro software.

Usage: gdalinfo [–help-general] [-mm] [-stats] [-hist] [-nogcp] [-nomd]
[-norat] [-noct] [-checksum] [-mdd domain]* datasetname
