Topic: Geo pin misplacement

I am using my new Panasonic DMC-TZ10 (ZS7) with GPS. I made a 100 or so pics in the gardens of a house. The camera puts both gps co-ordinates and country, city location string as metatags with the pics. The automatic geo pin positioning of Photosynth is off about 50 km to the east in a completely different city.

I'm seeing the same problem with photos that I Geotagged using Google Picasa.  They show up in the correct location in the more popular photo mapping web apps but Photosynth is placing them about 50 km east, as you've mentioned.
TonyErnst (Over 1 year ago)
Remember that a photosynth is made up of images, all of which have different geotags and we do our best to come up with an "average" location for the synth as a whole.  This may be off by a bit from what you expect, but the 50km you are reporting makes me think something else is going on here.  We're looking into this.

I just did a test synth with my brother's D90 which has a GPS attachment and the auto geotag did end up in the back yard of our neighbour from across the street, but I was actually standing in the middle of our street when I shot the synth, meaning that the geotag was only about 100 - 150 feet off.

I'm not saying that you aren't having this problem. I'm just saying that not everyone is experiencing it.

During my vacation travels I made a few 1000 photos which are to be Synthed. So far I synthed only the D'Artagnan statue in Maastricht The Netherlands. However, as reported for another synth before, Photosynth misplaces it on Bing Maps to the east in Germany. This is the link to the synth http://photosynth.net/view.aspx?cid=306ea121-e637-4fb4-95aa-b6baa4b79c93.
GPS equipped camera used is the one mentioned before.

To me it does not make much sense to start Synthing all the pics if Photosynth is misplacing them. It would be a tedious job to reposition them manually. So, please Photosynth team pay attention to this.

The browser link is fine. The only problem with the link in your first post is that the forum erroneously attached the full stop (period) at the end of the sentence to the end of the link.

Observe: 
http://photosynth.net/view.aspx?cid=306ea121-e637-4fb4-95aa-b6baa4b79c93 (with nothing attached to the end, it works)
http://photosynth.net/view.aspx?cid=306ea121-e637-4fb4-95aa-b6baa4b79c93. (with a full stop attached to it (or other url characters it breaks)


Share links are great for sending people to exact coordinates in a synth, but are long and ugly if you just want to send someone to the beginning of a synth.
Nathanael.Lawrence (Over 1 year ago)
Other ugly URLs include: 
having &wa=wsignin1.0 attached to the end of the synth URL (from when you just signed in to the site) or 
having &firstview=1 attached from when you've just clicked the 'View' button on the synther when you synth finishes uploading. 

Links with these URL fragments will work, but the &wa=wsignin1.0 will force anyone who uses that link to the synth to have a Photosynth account and be signed into the site, whereas using a clean link will work just like a link to a YouTube video - no need to sign into anything to just view it.

Example: http://photosynth.net/view.aspx?cid=306ea121-e637-4fb4-95aa-b6baa4b79c93&wa=wsignin1.0

::

The &firstview=1 attachment is harmless, but it's really not necessary and after serving its purpose the first time the synth really is viewed, just makes the link longer and more complex than it has to be.

Example: http://photosynth.net/view.aspx?cid=306ea121-e637-4fb4-95aa-b6baa4b79c93&firstview=1

Also, Joscelin, as much as I want this to be resolved for you and everyone else who is experiencing the problem, I can almost guarantee that you'll get this done faster if you just go ahead and make your synths and pretend that it wasn't auto-geotagging your synths and just manually geotag them yourself like most everyone does.

There's plenty of time between when one synth finishes and the next is being calculated to save a geotag. You can just drag the pin back to the sidebar and then either use the textbox to search for the correct location or you can just point your mouse cursor and zoom down with your mouse's scrollwheel - whichever is faster for you. It doesn't take long. ツ

Then may I add that it is not likely for someone as ordinary like me to remember the exact location of dozens of places on a vacation tour through part of the Alps. It would mean getting gps co-ordinates from photos, find the exact place on Bing or Google maps and then get back to the Photosynth webpage to set the location pin.
Nathanael (Over 1 year ago)
Pretty much. ツ It's actually not too difficult. Here's a small list of programs that will tell or show you directly on a map where the GPS coordinates for a photo are. 

Microsoft Pro Photo Tools 2: http://bit.ly/prophototools2 
(Shows you on a Bing Map where current coordinates are. Also contains an option to retain the GPS coord.s, but also translate those to the actual name of the place and fill in the location tags that are read by other photo programs.)

Google Picasa: http://picasa.google.com/ (Also requires Google Earth be installed)
(Very simply, highlight a photo and click the 'Geotag' button at the bottom of the screen. Google Earth will open and zoom to the coordinates in the photo.)

Windows Live Photo Gallery 4 Beta: http://explore.live.com/windows-live-essentials-beta (Requires Vista or 7)
Doesn't visibly display a map, but will read the GPS coordinates and automatically display the textual name of the location in the right hand tags pane.
OmniSynThesis (Over 1 year ago)
Thank you Nathan. I happened to become a Microsoft adapt since Windows 3.1 and Word 1. So, I use LPG 4 beta. As you say, it will only fill in the blancs and not give me the visual map point, which I would need to place the Photosynth geo pin manually. I think I will have a look at these Msft Pro Photo Tools some day.
To cut the discussion short... I sincerely hope the Photosynth team is monitoring this and will pay attention too it. I suspect it is in Msft's interest that the larger public is going to upload many photo(synth)s from their gps equiped smart phones. I suspect there will be a launch wave of such gadgets at the end of the year. Windows Phone 7 being one of them. All the material will facilitate the larger audience to have an enriched Bing Maps experience. Which in turn will create new business perspectives for the Redmond folks. Or, is this too much of a phantasy ;-) ?

Now synthing my shoots on Cuba, I find something to add to the original problem report.
In The Netherlands and France, being east from Greenwich, the Photosynth misplacement on Bing Maps is to the east. In Cuba, being west from Greenwich, the misplacement is to the west.
Latitude and Longitude properties in the photos come either from the camera's GPS sensor or from Live Photo Gallery's geotagging feature.

Why is there no one from Livelabs responding to bugs reported here?
Nathanael (Over 1 year ago)
JoscTr, just a minor note: the Photosynth team moved out of Live Labs and into the Bing Maps team back in 2008 and Live Labs closed in November 2010.

That said, I also often wish that there were more public response to the bug reports, but I know that they do read the bug reports. If you really need a response, try emailing the Photosynth team. http://photosynth.net/contactus.aspx
OmniSynThesis (Over 1 year ago)
Hi Nathan,Thanks for your comments. I wish there were a note on the about page about the current whereabouts and status of the team and development directions and priorities. I have the impression that some good things came out of Live Labs.

I feel that most people will stop reporting things, if it doesn't show that the team is listening. Photosynth is a crowd sourcing thing; team, be connected with your crowd!
OmniSynThesis (Over 1 year ago)
I had a further look at this today. First I have used Microsoft Pro Photo Tools. I have tested with photos having GPS co-ordinates from my camera. Locations are Netherlands, Cuba, France. MPPT shows for all photos the pin at the exact point I was standing on Bing Maps. I have also tried this with sets of photos I used for Synths. Perfect as well. Next I have uploaded some photos to Google's Panoramio. Also places them on the exact spot they were taken from on Google Maps. This definetely looks like Photosynth is having a problem with positioning a Synth correctly automatically on Bing Maps based on the GPS co-ordinates.
