Comparing OSM data with government data

[Dimitar5555]

The Bulgarian road agency has released a dataset of the republican and municipal road routes in Bulgaria. They have ref and geometry which can be matched to OSM relations (with network=bg:national and network=bg:municipal for respectively republican and municipal roads). Can Osmose detect the differences and report them?

The data is hosted on their website (https://api.bg/bg/gis.html) inside .shp files.

Yes it is possible to do this. It as already done for France and Spain.

For this tow countries it is only done on geometrical matching.

As first step I also only recommend to match only geometry, and when few geometry as missing, also check for ref.

Something like this must be setup

You can try to make a file like this. Even if you are not able to run it your self, it help to find the fields and the OSM tags required.
We can help to setup and test it.
