Going Jogging

Today while mapping I came across an intersection that shows the different types of artefacts that can be found in Bing imagery.

It’s possible to re-align background imagery in JOSM, but there’s not much that can be done here. Any alignment to one side will mis-align the other. There’s also a more subtle problem which can be seen below

These small imperfections are found throughout the imagery, and I’m not sure what causes them. The larger jogs are from the imagery as it comes from the providers, but I’ve found places where I have the source imagery from another source and the small jogs are not present in it.

Just for reference, here is the imagery from the BC Openmaps server.

Although much less colourful, this imagery is higher resolution and much more accurate and more useful for mapping.
