#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.

Oh, Seznam, and don't forget to ask for paid Premium plan for something you have actually taken from volunteers...

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.

@jmlich no, they are not saying that they use data about communications from OSM in the Czech Republic. You can't just blend OSM objects with proprietary objects of the same type. It's a license violation.

@jmlich Pepo, if you want to make judgments, please at least study the OSM license first. You cannot use OSM objects in a map where you already have proprietary objects of the same type. And you can list sources however you want.
They use OSM for everything in other countries. That's fine. They only use OSM for certain types in CZ, such as benches, recycling points. That's fine. They use their own proprietary data for roads and paths and they can't add roads and paths from OSM to them.

additionally it is question if it is their fault. Maybe some 3rd party daty provider made shortcut by using OSM data without considering impact to licence. Anyway, you can ask them to fix attribution ..

@jmlich it isn't about fixing attribution. It's a license violation. It's like as if Microsoft took GPL code from Linux and put it in Windows without releasing Windows as GPL. Attribution doesn't fix it.
Whether it was added by them or their supplier, is their problem and their legal responsibility.
It has already been raised with Seznam BTW.

omg we should create librestreetmap, something with bsd license instead of gpl ;-D this rule that it cannot mix same types of objects in maps is terribily complex to explain. Or even that you cannot blend two images is something is irracional. At least for me. But IANAL of course

@jmlich yes, it's a bit complicated, but Seznam navigates well in it. All they are officially doing is in line with the license. Except for these "quiet copies". That's why I think it's not systematic, but rather a failure of an individual or individuals who wanted to make their job easier. For the sake of Seznam I hope they will stop it. We also wouldn't want an engineer in our kernel team who would copy code from BSD to Linux. 🙂

Prasata jsou to. A furt si myslim, že by se OSM měla bránit.

I was searching for alternative to @organicmaps
after reading some behind the scenes
mapstodon.space/@atvirasis/114…
and now I see #Mapycz #Mapycom got other problems 🙈
Anyone can recommend good #OSM based app with offline maps for #iOS?

atvirasis (@atvirasis@mapstodon.space)

@organicmaps@mastodon.social this block should have been done earlier. It does have contributors from moscow, still spreading lies in Europe. Organic maps is a descendant of mail.ru's crap.me - NOT to be trusted!

@systemz @organicmaps I still hope it's just a failure of an individual or individuals who wanted to make their job easier and the company will fix it. It's only a problem for the Czech Republic, elsewhere it's pure OSM with their really good renderer on the top.
I use OsmAnd myself.

@GuloGulo Ne, Locus Map nedělají to samé. Ti používají OSM mapy a ty vykreslují vlastním rendererem, to je naprosto v pořádku. Seznam v ČR používá své vlastní uzavřené mapy, do kterých zjevně kopíruje prvky z OSM, což je v rozporu s licencí.
Není to žádná averze. Jen apel na Seznam, aby používal OSM v souladu s licencí. Jim by se taky nelíbilo, kdybychom data z jejich proprietárních map, za které třeba i zaplatili, kopírovali do OSM.

@GuloGulo Doporučuji nastudovat licenci OSM, než začnete vynášet takové soudy. Licence OSM umožňuje vzít objekty stejného typu a umístit je do vlastní mapy, ale nelze je míchat s objekty stejného typu pod jinou licencí. Seznam třeba bere z OSM lavičky, recyklační místa apod, ale nemíchá je s ničím jiným. Má tyto objekty pouze z OSM. V tomto případě bere z OSM objekty komunikací a přidává je do vlastních map, kde má komunikace pod proprietární licencí. To je porušení licence OSM. Locus Map nic takového nedělá.

Old thread but still. I thought this was a common practice - I'm from Slovakia and I remember I added some shops in #OSM and then when I checked #MapyCom , at least one of them was already in it with a slightly different name - probably added by user of #MapyCom . But then after the synchronization with #OSM (which happens every few days), they took just the shop I added (maybe merged them?). I suppose someone is sitting there and solves such conflicts

@efreet The thing is that unlike in Slovakia Seznam doesn't use OSM in Czechia. Except for a few object types: waste bins, benches... But definitely not roads or POIs which are part of their proprietary maps.
