#Mapycz (now #Mapycom) from #Seznam use #OpenStreetMap everywhere except their home country - Czech Republic, where they have their own proprietary maps.
There have been rumours in the #OSM community that they actually copy from OSM. Today I found proof that they really do.
I mapped a new park in #Brno just by surveying and taking notes last year. Later the park showed up on Mapy.com with exactly the same path layout. The new orthophoto is out and it revealed that I didn't get everything right and Seznam got it wrong too. Exactly the same mistakes.

Not cool, Seznam.

A screenshot from Mapy.com of the same park with the paths shaped the same way.
A screenshot from JOSM with the latest orthophoto in the background showing that the paths weren't completely correctly mapped.

@sesivany Yes, the same happened to me a few years ago. I've added a house that wasn't in photo maps yet into OSM, and it did appear in Seznam Maps in the same exact shape.
