Hello everyone, I was editing a very outdated map in OSM, and noticed how different satellite views aren't properly aligned with the entire map. The map aligns fine with Bing, but those images are severely outdated (around a decade old). I had to use a recent (or as recent as I could) satellite view provider, but everything has a small, but significant offset (maybe of 10-15 meters). Istead of realigning the entire city with the more recent satellite views, is there a way to set an XY offset to the satellite images so that they would align better with the existing data? or maybe a tool to realign every road in a city with the more up to date views? |

Yes. If you are using iD (the editor built into the website), open the background panel by pressing If you are using JOSM, there is an 'Imagery Offset' submenu under the 'Imagery' menu. Select the layer you want to adjust and the click and drag the in the main window to adjust the layer. Other editors that support lots of layers should have some similar mechanism. Take your time deciding whether to adjust the existing data or not. It usually isn't that big an improvement and it is a lot of work. It can also be a bit of a chore to figure out which layer is really more accurate. |
