Thank you very much. Generally I agree and having local knowledge is always preferred. But I think if nothing is there, mapping something that might be mostly correct and in a few percentage incorrect might be better.

Welcome to OpenStreetMap!
OpenStreetMap is a map of the world, created by people like you and free to use under an open license.
In most cases - Geoportal. Sometimes Maxar. Bing for Poland is mosty obsolate.
That's why it is so important to know the area on the ground. Then you can compare your knowledge with different arial imaginaries.
