I'm Attila Kun, a university student from Rákospalota, Budapest, Hungary.

My goal is to have OSM be well mapped in the area I live in and where I go (and where my friends live).

This includes good landuses, aligned roads, forest landcover everywhere and rivers, streams, buildings, addresses, POIs and other smaller stuff.


In Hungary:

Eastern Hungary and Budapest mainly, but i touched some parts in Western Hungary. Edit counts: 283,194 [1]

In the US:

Edit counts: 2,408,282.[2] However, I learnt a lot by mapping that country, because it has so different landuses compared to Hungary, where there are many croplands crowded into a ~100 acres of land (or more..) I mostly map forests and align roads there, aligning the TIGER import mess, every state has poor data, but West Virginia is doomed completely, so i aligned a lot of roads by mapping that area.

Currently in progress:

I also made some presentations, like how I mapped USA or my own area: Github link

It may happen that I don't map for a while because of university studies or personal life.
