I noticed an area where the air photos are shifted quite a distance to the left. When you follow in Suriname the road from Pengel Airport to the north, to Paramaribo, you will notice that suddenly the road jumps to the left. A few kilometers further north this road jumps back to the right. So the whole picture over this area has shifted to the left. This makes adjusting the map difficult. Is there someone who can repair this?

Which imagery are you looking at? Is it Bing, Esri, DG..?

If you mean here? https://www.openstreetmap.org/#map=19/5.81587/-55.17647 I would suggest that more gpxes need to be recorded and uploaded. The images may be 4 to 5 meters off the line of the road ( a car length maybe) but you need more gpxes to confirm where to check and possibly adjust the imagery before you move the roads and buildings. But they maybe OK.

I mean here: https://www.openstreetmap.org/edit#map=18/5.48774/-55.18410 In Bing air photos, in the edit mode.

Ok. i think you need several gpx traces to know where the error is.

Ok. Shifts like that used to be quite common in older aerial imagery. If you're using iD, I'll suggest that you click the "Background" icon and select either "Digital Globe Standard fotos" or "Esri World fotos". None of those exhibits the shift seen in Bing imagery. Also make sure to compare with the various gps tracks around the area.
