I have been using PTP for a few years now. I'm doing a project in China which requires us to use the map function with openstreetmap as google maps are very poor in our location (South China). The problem is I can't find a way to show OSM in PTP's UI instead of google. If I put the pins linking to the pano images in the right place on the google map they show up in the wrong place when I load the pano online (in OSM). This is because the Chinese government restricts google maps, forcing google to make them show a certain degree of error, where as OSM is unrestricted. I also downloaded a demo of the new PTP 2.0 but I could not get OSM to display in the UI either, I would happily pay for an upgrade if this was possible. Dose anyone else have problems with nodes showing up in the wrong place when switching between different maps? If we can't get OSM inside PTP then is there a work around for correcting a large number of nodes between one layer and another?
