Did the leaves fall off? Something not working right? Let us know how we can improve the Photosynth experience.
I've noticed that the auto-geotagging feature is not working correctly with my photos: the geotag point seems to have the correct latitude, but the longitude is too far to the east.
Please see this example:
Photosynth placed it in a eastern suburb of Paris, but the photos have geotags around Tour Montparnasse, which is a office tower just south of central Paris. Other programs correctly place the pictures at this location.
Hi, You are correct with your observation. I have reported this bug here over a year ago. Someone from Switzerland also reported it. I am in the process of migrating my Synths from one account to the other and I am experiencing this problem again. I have loaded photosets with Microsoft Pro Photo Tools and with Google Picasa. Both Msft PPT and Picasa show off position to the east. It varies from some km to more than 50 km. The difference between placement on aerial maps of PPT and Picasa is only a few hundred meters. After changing the gps co-ordinates of the photosynths by repositioning them on its Bing Map, then Photosynth has no longer a problem to position a Synth on Bing Maps correctly. This makes me suspect that there is something wrong with the gps software of my camera. It is a Panasonic DMC-TZ10.
I took a little time to test. I forced a GPS sync with my camera and shot 1 photo. I checked with PPT and Picasa. Both show an offset of about 5 meters to the east which is within GPS accuracy, I think. I did the same with a set of 40 photos and checked them as a set. The set shows exactly on the spot. However, generating a Photosynth with the set results in a Photosynth auto positioning of about 50 km to the east of the actual position. I will no further investigate this, but I hope the synth team will, as this is causing a nuisance.
Wow guys, I think I have got the reason why because of a conversation I had on the Google Panoramio help/support forum! Exactly, it is not the latitude, but the longitude!It is because our earth has a daily turnaround. GPS satellites are in geostationary orbit. They tell the point on the fictional sphere, but the place on earth depends on the time of day. This means that if something is wrong with the clock setting of the camera, like summer/winter time setting, then there will be a longitude deviation! It is that we have Lawrence here for many good answers, but the Photosynth team is doing a very poor job on supporting its community!
