The photos and ADAHRS data were taken along with using camera and ADAHRS devices which were installed on the UAV while the aerial observation was done. The data which were taken from ADAHRS consisted of date, time, air speed, GPS coordinates (latitude and longitude), altitude, temperature, air pressure, and UAV’s orientation angle (roll, pitch, and yaw). The method used in this system included custom tag configuration, extracted photo metadata, the synchronization between ADAHRS data with photo metadata and integrated data between ADAHRS and photo metadata. The configuration, extraction and integration process were done with using ExifTool which was a library and command-line application to read and write metadata files. Datestamp and timestamp which can be found in photo metadata and ADAHRS data were used as a parameter of integrating the data on the synchronization between ADAHRS data and photo metadata. The systematical experiment was done by using hardware functional test system which composed by reading the date and time on the RTC module which was already synchronized with the Western Indonesian Time (GMT+7) and the ADAHRS saved on data logger, also with the test on the effect of various image’s resolution and the number of photos to the duration of the whole process which was done by the system. This system was able to integrate ADAHRS data from the various image’s resolution, which were 230 pixels x 1536 pixels, 1920 pixels x 1080 pixels, 1280 pixels x 720 pixels, and 848 pixels and 480 pixels. The amount of average of time from the process that was done at the fourth experiment were 3,936 seconds per 100 photos, 7,454 seconds per 200 photos, 11,156 seconds per 300 photos, 14,740 seconds per 400 photos, and 18,460 seconds per 500 photos. Besides, this current system can be able to make the backup file from the extended version of photo metadata and also retain the originality from that photo metadata.
