Hello, my name is Attila and I'm 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 land uses, aligned roads, forest land cover 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 (especially in Somogy and Zala Counties).

Edit counts: 443,436.[1]

In the US:

I learnt a lot by mapping that country, because it has so diverse land uses 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've already aligned a lot of roads by mapping that area. (Although, I'm focusing on mapping ONLY forest land cover recently)

Edit counts: 10,570,943.[2]

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/work or personal life.
