#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.
