Hello!

I’m a mapper, validator and trainer who’s continually learning and seeking to improve.

I aim to provide clear, concise, valid, accurate and timely feedback to help OSM users improve the quality of their contributions, and subsequently the map.

Natuarally my interpretation is not perfect; if you see what you think is a mistake, then do not replicate it and feel free to ask about it.

Below are some useful links to various resources that have helped me; I hope they are also of benefit to you.
