Help about fixing wrong ferries in İstanbul

most ferries are removed or wrong in currently. I work hard to fix some of them but need your help. please look at this Changeset: 162771973 | OpenStreetMap

Hello my friend!

I’m not quite sure what you need help with, are you just looking for people to also work on the ferries with you or is there any specific issue, you need help with?

PS: I don’t read Turkish, but you can write in Turkish if it is easier for you to explain the issue there. People can use the machine translation to understand it.

yes, exactly. They’re quite old and wrong ferries data in İstanbul. I need people to help me fix this

Are you sure you’re allowed to use the attached pdf for the ferry routes?

Also, I think it would be better if you reached out to some local mappers who know the language. I am focused on Denmark for now.

im from istanbul.

what do you mean by “allowed to” ?

Hi @AnanasSuvyu.

If Şehir Hatları copyrighted this data, you cannot use it.

In these cases, I try to find open data sources. For instance, haritakaynak’s resources page is a good place to start. They list IBB data portal as an open data source. When I checked IBB’s data portal, I found the ferry lines data set, and the page says it was updated on 04/02/2025. Quite up to date. I am going to check if IBB’s licence is compatible with OSM. If it is, and if I have time, I can help you to update the data.

I think this kind of work is a small project on its own, and some research and planning is needed before diving into it and adding, editing and deleting data on the map.

@AnanasSuvyu I’ve checked, the data provided by İBB is licensed under Creative Commons BY 4.0, which can only be used if they sign a waiver document.

I will contact some local mappers to see if anyone has attempted to contact İBB about this. Hopefully we’ll have them sign the document for the datasets we can use.

But until then, please continue your regular contributions, and do not delete the ferry lines, or add new ones. Let me know if you have any questions. Thank you.
