Four years ago on May the 25th 2018 the, then new, EU-wide General Data Protection Regulations (GDPR) went in to force. It is therefore quite fitting that nearly to the day 4 years later, the OSMF has given up any pretense of ever fulfilling the legal requirements arising from the regulation and, perhaps more important, undertaking the ethically and morally indicated steps to protect the privacy of our contributors.

It isn’t as if the OSMF was caught by surprise in May 2018. The topic was by far the best researched, documented and planned change in its history. And it isn’t as if the quality of the work or the conclusions were in doubt, completely independent and unaware of what had been prepared by the LWG three years earlier, at last years SOTM there was a talk by Robert Riemann that came essentially to the same conclusions.

But, four years later, with the sole exception of new users having to accept the OSMF terms of service on sign up (added by yours truly), none of the required changes to the APIs and data access have even been started on OSMF properties.

To make the situation worse, OSM isn’t simply static, new services, third party and OSMF operated are being added, existing operations are changed and rarely are the data protection impacts and consequences considered.

Ironically some organizations in OSM-space have taken required steps, for example Geofabrik, OSMcha and Pascal Neis’s HDYC, that the OSMF has not.

Why have we ended in this fraught with legal and financial danger place? On the one hand there are no brownie points to be won with championing the changes to the OSM website, the API and data distribution. Since Frederik has left the board no director has been willing to show any support for the matter.

Yes, you heard it right. It’s about the 2nd mapping workshop. Shouldn’t it follow by the very first workshop, since the last article is about the first expedition? Let’s not get bogged down with the series ordinal, that’s another story for another time lol. Some say that it’s possible to notice from the last article, and we can chit-chat about it physically at the next meetup if some insist… All we know is, it's not called the Stig!

2nd Mapping workshop in MozTW Space Taipei

In brief, OpenStreetMap Taiwan Community (OSMTW) utilised data collected from surveying in the 2nd mapping workshop at the MozTW Space Taipei after the junket tour maiden survey expedition. Oberserved physical attendance has dropped due to the recent increasing communities infections of the Coronavirus Omicron variant. Be that as it may, the workshop warmly welcomes two enthusiastic geography teachers to join.

對，你沒看錯，上次是第一次的街景踏查團，但這次是第二次的編輯工作坊，至於為什麼不是第一次的編輯工作坊，嗯……說來話長，還是不要在這邊寫好了XD，看上次的日記或許可以看出一點端倪，或者在聚會時與我們聊聊。

▲在摩茲工寮舉辦的第二次編輯工作坊

總而言之，繼上次的街景踏查團（公費旅行團）後，開放街圖臺灣社群（OpenStreetMap 臺灣社群）在2022年5月22日於摩茲工寮舉辦了用來編輯街景踏查團蒐集到資料的工作坊。由於台灣疫情因素，導致實體活動的參與人數銳減，也同步影響這次第二次工作坊出席人數。不過仍然有兩位地理老師來到現場。

Hello World!

Hi everyone, I’m Chris Park, a Computer Engineering student studying at the University of Toronto! I’ll be working on Valhalla, the multi-modal routing software based on OpenStreetMap, on my project for the Google Summer of Code.

I’m an active explorer, and I love searching for new experiences. I enjoy playing the viola, trekking, and traveling in my free time.

I first ran across OSM on a pathfinding GIS project to map cities around the world, leading me to dig deeper into how the mapping tool was built and eventually apply to contribute through GSoC.

Project Goals

The aim of the project is to re-enable transit pathfinding support to Valhalla. The routing app no longer supports transit pathfinding because of updates to a dependent API, although it originally had the functionality. Therefore, the goal is to import raw GTFS (General Transit Feed Specification) and format it so it functions with the existing code, so that transit support can be re-introduced without third-party dependencies.

Since Valhalla previously had transit functionality some of the code can be re-formatted to match the new data form rather than writing fresh code. This will allow for transit data to connect easier to the rest of Valhalla and help complete the project in a timely manner.

To achieve this, there are four broad milestones to meet:

1. Importing GTFS data and ensuring it is readable in Valhalla

2. Converting the data into tiles to match the format of roads and features.

3. Connecting the tiles into the road tiles such that transit tiles are integrated with the rest of Valhalla

4. Testing the connected network with Valhalla’s gurka tests to ensure functionality

By the GSoC midterm evaluation period at the end of July, I hope to have completed creating the transit tiles so that the latter two months can be used to connecting and debugging the data.

Hello!

Hi, everyone! It is so glad to be in this community starting a new challenge this summer.

My name is Zhengyi Cao, a Chinese student at Boston University majoring in Electrical and Computer Engineering. I touched OSM by the chance that one course project required the achievement of finding shortest path by using OSM resources.

I am very interested in doing something like building maps, exploring unknown area and planning trajectory using point cloud data or other helpful approaches. It's challenging and addictive, and that is why I apply this project and be so eager to do this.

JOSM route visualisation

That is the topic I choose for this project. A plugin that can clearly display the full picture of the public transport route and show the relevant information about the designated route, which is convenient for users to query and greatly improves the efficiency of map modification. I am responsible for the improvement of UI to interface.

Points needs to be Improved (initial idea)

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.

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:

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
