Yes, I’m allowed to indirectly use that data as I’ve described.

The first and most important question is what is the licence of the data you have? Is that licence compatible with OSM?

Cheers Chris

I have a dataset of Tehran roads (in Iran) with name of all roads. Many roads of Tehran are not named in OSM map yet. 

Coordinates on my dataset does not exactly match the ones in OSM, but I did a job and for first step I extracted very very matched records. These roads are only two node roads and also I programmatically put restriction is order to be sure the matching confidence is highest possible. So from about 155 k road records in my dataset and  44k road records in OSM data, I did extracted about 4K (exactly 4464) records where are closely match and from these road records 1376 roads are un named in OSM database. So I know the name of 1376 records in Tehran which have not name in OSM database. 

I can make a spreadsheet file with two columns of osm_id and name of those un named records to update OSM database. After that how can I update the OSM database?

This is first step, after this I’ll try to extract more matching data…


Thank you
