El trabajo de Diego, lo vi, es fenomenal. Como me gusta la autopromocion, durante mis tres meses de viaje en el Peru en 2014, he puesto como 500 notes (300 ya lo corregí), he grabado y subido GPS track de todo el viaje para uso en OSM, he mejorado un monton de rutas principales en el Peru, y he puesto la informacion sobre pavimentacion (surface) y calidad de las rutas (smoothness).

Si usas Osmand, se puede actualizar el mapa cada semana.

Because of population density? This is what Japan looks like at night, a good proxy for population density within a country (actually population density * prosperity * measures to decrease light polution). Striking similarity, no. It could be interesting to overlay both images and look for outliers. A bit like I believe members of your team did some time back, but using image complexity in stead of population density as a predictor of expected data density.

Thanks for the write-up. Looks like a good way to fix errors. Can’t see how anyone could have anything against this method.

@SomeOneElse a more systematical approach is needed to get statistically valid results. The good thing is, the longer we wait, the more likely we have enough data :) I’d like to look into this further in June 2015…

I think Switserland and Belgium might be interested in the automatisation. I’ll send this diary to @xivk from Belgium. Do you think you can share this?

We had some success in Belgium. I think we recruited some people for the Meetup group.

Please don’t kill overpass :)

Just only make the call after a certain zoomlevel is reached?

I’ve been navigating for 25000km through South America, using Osmand. In general, quality is definitely good enough, though making notes of all the errors made me a top 50 note maker worldwide :)

Now that I’ve actually tried the thing: - the “world map” only shows café’s that already have the info? I’d like to be able to browse the map to check for places I know, not just places closest to me. - the rendering doesn’t seem to show plaza’s clearly, good points of reference when it comes to café’s - the little map for a café isn’t always very clear. It would be nice if you could zoom in/out there as well

@Dietrdreist, I’ve been adding that tag on the road with Osmand. It’s easy! If you’re a mapping nerd! But with a dedicated editor it might be easy for any old nerd.

Anyone who defines themselves as an expert on OSM is an expert on OSM. Do we need to formalize that? If we do, we might restructure our communications system Reddit style. Edits and comments can get you positive and negative “karma”, which is the opinion of the rest of the community. Bullies would easily get downvotes, making their behavior less rewarding.

It’s the nature of OSM that opinions will differ. New contributors who cannot deal with that, might not be the most suitable contributors anyway. But the more discussion about “the right way to map”, the more probable that some formalization will take place, right? If you have a real voluntary “human validation process”, you do indeed need some guidelines. As @tmcw said, database conflicts might be a problem. So approval has to be as quick as possible. Changeset approval and discussion should thus be separated. If things are “about right”, approve the changeset and open the discussion afterwards on how things can be done even better. Only if things are really bad (breaking things, doing things in completely different ways from standard practice), disapprove. For example, breaking a relationship would result in disapproval, mapping landuse including ways would be approved but commented upon.

Again, anyone could sign up to approve or disapprove changesets. But anyone can “upvote” or “downvote” their decisions. People with too many downvotes could be excluded from the process if the need arises.

When it comes to time and energy, I believe the first priority should be on making some automatic error detection. Because even experienced users make mistakes, automatic error detection can help everyone.

@Rob, would very much like to help out. I’ve got a thinking session on my to do list about dealing with and preventing (new) contributor mess-ups, which sounds like a similar communications problem

Absolutely love the concept. Would like to see an application to add WiFi availability this easily.

Just passing me the ball now, aren’t you :)

Well, I do like to think about things like this, and I don’t have enough internet at the moment do do a lot of mapping (apart from making notes and adding POIs). So maybe, maybe.

Examples: The sad story of a new contributor messing up http://forum.openstreetmap.org/viewtopic.php?id=27704 , and someone who’s annoyed osm.org/user/Gerald%20Weber/diary/23680

The solution of course can’t be all technical, but I do believe editors should warn you when they think you’re doing something strange. But how about giving a contributor the option to “send changeset for review” when this happens? An experienced user can probably approve, comment or disapprove ten changesets in the time of one revert.

This is a recurring issue on the diary and on the forum. I think we should try to join forces and write up some proposals. I’m sure that we can do better than we are doing now, both protecting data integrity and contributors making mistakes… Then, it will be easier to stay patient.

Here’s another simple way to see if the most important roads in your area are already tagged as paved/asphalt/concrete: using Overpass

Asi que me fui a Ayacucho. La primera impresion era pesimo: llegamos de noche, bajo la llucia - que caotica la ciudad! Pero de dia parecio una belleza el centro; y que encanto esta zona con puro calles sin trafico y mucho espacio verde. No vi algo parecido en el Peru!

En cuanto al mapa: bien bonito, pero le falta informacion basica. Por ejemplo, aqui la calle 28 residentiales de hecho son gradas. En esta zona, falta definir one-way streets. Y me fui hacia Cuzco por esta carretera “trunk”, qua aun es muy bonito, es mucho mas lenta que la carretera supuestamente secundaria que es mucho mas amplio y rapido. (Se juntan aqui, y ya cambié la classificacion.

Como no es muy facil hacer la travesia de Ayacucho, seria importante classificar algunos de las calles residenciales como tertiary o secondary para dirigir un poco el trafica hacia calles aptos para esto. Si es que existen calles aptos :)

Gerald, That’s exactly how I would like to see it, and how I used to map in South America. Unfortunately I’m afraid that’s not realistic in Peru and Bolivia, where that would imply mapping a lot of the most important roads in the country as tertiary …

As a heavy, happy, old fashioned Potlach2 user I am glad to hear it is still alive.

And yeay for the undelete function!
