Summary
editDescriptionEastern part of Tanaga Island Alaska.jpg |
English: Here we are looking at the eastern part of Tanaga Island, Aleutian Islands Alaska, USA. SFO to TPE flight UAL 871. Taken with the assistance of Yingyu Deng.
The three pictures in the series all had the same GPS time and position, getting 17.5, 76.4, 117.5 seconds behind in their GPS updates. We noticed that the Location for this photo seemed wrong, so using ExifTool on the tags of the original file we found the photo's GPSDateTime was slower by 117.5 seconds than its SubSecCreateDate. So the GPS was not updating although the plane kept flying! (Note, different cameras have different Exif tags. Some might not even have GPSDateTime. And some with an up to date GPSDateTime might still say we are at coordinates 0,0!) Luckily we had downloaded the flight track KMLs from e.g., FlightAware (during the one week after the flight when they offer them for no charge.) Then using GPSBabel we interpolated a better coordinate pair for where the plane was the second the shutter was clicked, for our new revised Location! The GPSBabel team has squeezed an extra 146 meters out of the data just for us! We are at 32,000 ft. altitude for all three photos. |
