Urban road classification is hard. OSM’s highway=* classification scheme is defined nebulously using “importance to the road network”, and the examples given to illustrate importance are often more suited for rural roads. Generally, road classification seeks to identify the important destinations in an area, find the routes that best link adjacent destinations, and rank these routes based on the importance of the destinations. But this is difficult in urban areas, where there are often many closely packed destinations, and many parallel possible routes. Since the distances covered are often short, a local may choose a different route between two destinations based on the time of day, expectations of traffic, or simply on a whim, without great time differences. However, a hierarchical road network certainly exists in all cities, though it may not be entirely apparent to a non-local, or even a transplant until they’ve lived somewhere for many years.

Edificios:

Muitos edifícios são muito próximos mas na verdade não se tocam. Tente mapeá-los o mais próximo possível, sem permitir que eles se conectem entre si ou com as ruas. Caminho para pedestre: Selecione a tag “footway” - caminhos acessíveis apenas a pé.

In the OSM wiki there are some templates (KeyDescription and ValueDescription) that are used by Taginfo to show some useful informations to the user; since the same information is contained in the Data Item linked to the feature page, some wiki users, in good faith, shorten these templates to their minimum (e.g. “{{KeyDescription}}”), thus preventing Taginfo from fetching the data.

This is what ref:mise on Taginfo currently looks like: taginfo-wiki-description.png

I think that this issue is on Taginfo side but, for the time being, it doesn’t seem to be on their To-do list; for this reason, I believe that we should preserve (or restore if removed) the information stored in these templates (even if this means maintaining the same information in two separate locations, i.e. the Wiki page and the Data Item page).

Here is a sorted list of the OSM Wiki pages (tags or key related) which contain the text “{{KeyDescription}}” or “{{TagDescription}}”:

For my work at anyways.eu, I’ve been tasked to make sure that all schools are in OSM - especially with capacity.

No better way to do this by making it easy for contributors to add the correct data… So, I wanted to create a MapComplete theme for education. Normally, I would open up the wiki to see what tagging is needed, but for schools there is very little tagging available at the moment, which is a mess.

As it turns out, schools are diverse and this is reflected in the tagging.

This diary entry serves two goals:

  1. I want to organize my thoughts on how a tagging model could look like
  2. It is meant to stir up some discussion.

Hopefully, some tagging proposals will come forward from from this post.

So, what is a school (or educational institute) anyway?

This is already a hard question. The openstreetmap-wiki on ‘education features’ states:

Education features are map objects and object features which relate to educational activities

Well, thanks, captain obvious.

Let’s turn to the International Standard Classification of Education (from Unesco) instead:

As national education systems vary in terms of structure and curricular content, it can be difficult to benchmark performance over time or monitor progress.

So, in other words, it is difficult as this can be highly different amonst regions. The ISCED-document however does a good job to draw some lines and to give some definitions.

What does a standard school curriculum look like?

In most countries, the school trajectory for most people (according the the ISCED, page 21) looks more or less as following (but the precise ages can vary with a few years):

Before formal education starts, kids younger then about 4 or 5 go to preschool/kindergarten. This is optional in most countries, and some education takes place, often to prepare spelling and simple math. ISCED calls this level 0

Продовжую виправляти проблеми мікромаппінгу, які виникають, після втручання мотивованих новачків

На цей раз звернув увагу, що в одній частині міста, Komoot відображає якийсь концтабір замість приватного сектору або локацію зі зйомок “Той, що біжить лабіринтом”. Виявилось, що кожен вхід в приватний будинок був позначений точкою gate. Це все рівно, що на кожен будинок нанести точку, яка обозначає місто (і на кожному будинку буде здоровезний напис Citiname), тобто, це надлишково, не несе ніякої практичної цінності, не тільки ніяк не допомогає при навігації, а і шкодить, забиваючи візуальним шумом. Gate потрібен для конкретного вказання обмежень переміщення через певну дорогу. Наприклад, візуально можна подивитись, і побачити, що дорога не вільна, вона закривається воротами, але без заборони доступу. Чи навпаки - ворота з закритим доступом. Саме тому, ця точка відображається на навігаційних велосипедних мапах. Теоретично, таке позначення воріт буде корисна лише у випадку, коли хтось захоче підрахувати загальну кількість воріт у місті. Але перетворювати мапу міста на великих збільшеннях у суцільні ворота для цього мабуть не треба.

Here are a few edits I’m interested in making in the coming months. I’m hoping to get feedback and discussion here.

Use of Directional Prefix on Streets

The proposal here suggests a system that would change street names such as “East 200 North” to just “200 North” and moving “East” to name:prefix. This system is already in use in Salt Lake City and in my (limited) testing seems to work fine with geocoders. example

Some streets in Logan have already been changed to this format. Personally I think consistency throughout the city is more important than the tradeoffs between each way of doing things.

This change seems relatively simple to update all at once using an automated edit.

Address Import

Address data is available from UGRC, and according to the Wiki it looks like the license will work with OSM. Other than a few exceptions sprinkled here and there, the vast majority of Cache Valley does not have address tags.

Challenges

  • I don’t have experience with making automated edits, but am moderately confident at scripting, so I’m confident I could figure it out especially since there are a few wiki pages describing the process others have used.
  • Because of mostly hand-traced building outlines, there no doubt will be hundreds of conflicts or corner cases that will require manual review and possibly in-person survey. I’m happy to go in person to check an address in the valley, but one guy can only do so much of this. I’m not sure what system (if any) is best to queue up manual review cases and mark them as solved. Notes? fixme=* tags?
  • Building outlines have not been completed in Cache Valley.

I’m open to any criticism or comment on anything discussed here, or on other edits that might need to be made to improve the map!
