Any distortion is due to the software that changes imagery from oblique to overhead having difficulty dealing with steep slopes and objects that are above ground level.

Ground level objects on the map might be between 3-5 metres of their real world position, but tall buildings and bridges, etc. get distorted.

I might have another look at this. However, while we can edit things to make them more accurate, getting them precise is another matter.
