I am a very enthusiastic Panoramax user, and link them to OpenStreetMaps where possible. However, I noticed that many of my Panoramax photos have moderate to serious GPS errors (as much as 10-30m), especially in dense urban environments.
Is there a way to update these GPS coordinates manually? Right now I download the photo, manually edit the EXIF, upload it back to Panoramax and delete the original. However, this does not scale up.
Suggestions are most welcome!
Shouldn’t that some what mostly do away with the need for “exact” coordinates? Not saying that it isn’t an issue, but “urban canyons” are always going to be a problem with GNSS.
PS: there’s no plural s in OpenStreetMap.
Not necesarily. Providing POI images is not the only use of Panoromax photos. They are also incredibly useful to mappers. For example ID editor has overlays for Panoramax images. If the coordinates are wrong, then it gets confusing.
Besides wrong is wrong, and should be corrected. It is usually trivial to find the correct location if you know the area.
Not exactly. I keep my uploaded Mapillary (haven’t switched to Panoramax yet because Mapillary has a JOSM plugin) photos until after I’ve had a chance to look them over because the position correction in Mapillary is not always great, particularly in spots where there’s only one or two tracks and not dozens. Mapillary does seem to try to triangulate what it sees in the photos against the EXIF position and HDOP and viewing angle to nail down the exact position and viewing angle and seems to get better with additional data. I’d be curious (and unsurprised) if Panoramax does something similar (and if not, I’d like to request that because it’s really handy in Mapillary).
There’s the photo geotagging in JOSM, but that runs back into the problem of “Panoramax doesn’t have any JOSM integration”. It’d scale up a lot better if JOSM had a way to lasso or rectangle select multiple geotagged photos at once for movement or deletion (a great deal of ending a session for me is deleting locally stored images, of which I have probably about 2 TB worth of imagery right now, so trying to manage this one image at a time is painful).
We do nothing like that in Panoramax.
We have in mind some “snap to road” feature, but not started working on it yet.
JOSM can be useful to check if some picture have very bad geolocation, and fix them prior to do the Panoramax upload.
I’d hope this would be viewer-togglable since if you’re trying to work out where exactly something is by photo, it would be more useful to know were the photo tells us it was taken than the nearest location on the road centerline to it.
Sure it will be on request because we also have RTK based location on many pictures shared by large municipalities.
@cquest a simple way to edit the gps coordinates of a photo on the panoramax website would go a long way here. Most of the errors are trivial to fix if there is a nice UI to do it.
