If you are interested in validation, check out our validation guide on using OSMCha. Do keep an eye out and comment on changesets which seem inconsistent to let the user know which will in turn helps users become better mappers and lets us maintain data quality on OpenStreetMap.

Look forward for another roundup next week.

Via is often part of the name and is on the street signs. I means “ the way to “ and is very common in Italy but is also seen in several countries. It is possible to contact the mappers of errors or possible errors directly instead of leaving notes in the data, while using Josm or Potlatch2 editors by ( or via !!) email. I was guilty of not connecting the ends of dirt footpaths ( rights of way in the UK) in my early mapping. I was contacted and informed that connecting end node allowed route apps to work. Dirt paths shouldn’t be deleted just because they are dirt, many in the UK are the legally recorded rights of way. Happy Mapping

Yes, “via” means “road” in italian.

I mean, “via” is what you use in road names: “Via Roma” is like “Rome Road”. (sorry, I clicked save too fast)
