"..mappers as a whole are mapping more features (buildings, houses, libraries, schools, green spaces etc) within the wealthier areas of the Dublin region than in the poorer areas." {53degrees} 

Background

The following assertion was made by a blogger around 18 months ago:

"..mappers as a whole are mapping more features (buildings, houses, libraries, schools, green spaces etc) within the wealthier areas of the Dublin region than in the poorer areas." {53degrees} 

It was made here and in a follow up here

Reading the two posts together with the twitter promotions for them it is clear that the hypothesis rests on the perception that OSM contributors, specifically those contributing to OSM around Dublin, suffer from some kind of collective unconscious bias, to the extent that they have neglected the deprived areas of Dublin and mapped the affluent areas to a higher level of completion. This assertion, if well founded, would reveal that not only does the map of Ireland, specifically Dublin have gaps, - but that these gaps are patterned in such a way as to further exclude and marginalise the residents of these areas and the second blogpost makes no doubt of this consequence.

We have a great name for the band!: "The Spurious Correlations"

The author refers to 3 or 4 examples of poor areas, sparsely mapped, compared in turn to affluent areas mapped to a higher extent using visual assessment. There is no transparent methodology or apparent logic for these comparisons other than they were what the author appears to want to choose. Perhaps they are conveniently selected to suit the conclusion.

The author repeated the claim on twitter [now deleted] on the 23rd October 2020, presenting the evidence of these three or four comparisons as conclusive proof of a “startling lack of completion of working class areas in osm, a citizen science project”. Some charts were shown, demonstrating a very selective method of counting tags. Whether this represents traces of a deeper investigation remains unclear. This needs to be tested here and now.

Transparent Method

An inquiry with some more rigour than the two blogposts is much needed now. The first step is to refer to the deprivation index available here, and identify 10 outlier electoral divisions that are the most affluent, and 10 outlier electoral divisions that are most deprived¹. If the assertion holds weight it should be detectable at the outlier values.

The ED boundaries were downloaded from the CSO website and the deprivation index was downloaded from the Irish Government’s official data portal and matched to these boundaries to enable comparison².

The OSM data was extracted as a .pbf tile from Geofabrik on the evening of the 23rd October and parsed in a PostgreSQL database to exclude areas outside the boundaries of the electoral divisions. Three queries detected the three types of object geometry which is what the blogger’s assertion rests on and simply counts them. A fourth query detected In the case of ways and relations it included those that were partly inside the boundary³.

The calculations are simply the aggregate count of all types of objects, further aggregated into an affluent total and deprived total, and then divided by the size of the area to fairly reflect the fact that the areas vary from 1.06 square km (Avonbeg) to 5.96 square km (Priorswood).

The Result

Let’s get down to it…

The first result produced is a count of all objects in the 20 extreme affluent/deprived areas, grouped into those categories, aggregated and normalised by the area size of the total electoral division area. Ultimately this counts and compares the density of mapped objects in the two groups of areas

	Affluent EDs objects per Sq KM;					Deprived EDs objects per Sq KM;
	696					1,173

This result disproves the blogger’s conclusion about deprived areas being neglected by mappers. I will provide a separate diary post showing changeset dates to demonstrate that from 2016 a big upturn in mapping of Dublin’s deprived areas took place, and a rationale for why that began to happen, but that is for another day. And now for the tagging depth result…

	Affluent EDs Tag3+ objects per Sq KM;						Deprived EDs Tag3+ objects per Sq KM;
	652						186

This shows that the affluent areas, though having less object geometry are tagged in somewhat more depth and detail. The figure may be skewed by two of the Affluent EDs which has peculiar characteristics, these are Mansion House and Rathmines East. The former has several city centre streets with specialised Government and Commercial services, however the latter is mainly suburban with a few shopping districts. This does support a totally new hypothesis of more nuanced mapping effort in Affluent areas, but more nuanced does not mean more “complete” as the original blogger’s claimed. The ages of the changesets suggest the original object geometries were typically provided around 2010-2012, and more osm contributors using on-the-go editors like StreetComplete, Vespucci, maps.me and OSMand.

Conclusion

These results, despite the finding of more detailed tagging in the affluent areas, do not support the main hypothesis that Dublin’s socially deprived areas have been deprived of mapping. It would appear that the mapping for these areas is at a higher level of completeness and will be easily converted into tagging depth. There is nothing in the original idea that provides much insight into either the OpenStreetMap community and its mapping preferences, neither is there much to increase the cause of Dublin’s deprived neighbourhoods. A further diary entry will deal with some of the extraneous claims and wrong assumptions made, but that is for another day.

I got off my butt at lunch today and walked a bit more of Daytona Beach, FL, USA.

Part of the walk was on International Speedway Boulevard. While there I fixed a building (a church was purchased by Bethune-Cookman University), verified a few others, and added some missing businesses.

On the way in to work I added a business. I’ve decided to try to add one new business along my commute every day.

Slowly we progress.

As anyone mapping in the UK knows, in most areas housenumber coverage is abysmal. For example, in osm, germany has 14 million housenumbers, USA has 10 million and the UK has about 1.6 million (as of 2018).

Therefore, an open data source of housenumbers would make it significantly easier to add housenumbers. The only other method is surveys, which is slow and tedious and can only really be done over a small area.

It just came to my attention that an out-of-copyright map from the National Library of Scotland of housenumbers and buildings in London is available for OSM. This is a old map, that was surveyed from 1944-1967.

Due to this, lots of construction and destruction has taken place since then, so in some areas of London, this map will not be useful. However, many buildings have remained the same since then, and if that case this map provides a far, far quicker way of mapping housenumbers compared to going out and surveying them yourself.

To test the imagery, follow these steps (in JOSM):

1. Imagery –> Rectified Image
2. Select “Custom WMS Link”
3. Enter the following string into the textbox (including the “tms:” part): tms:https://geo.nls.uk/mapdata3/os/ldn_tile/{zoom}/{x}/{y}.png

This map extends to Brighton and Southend, although it does not provide housenumbers in those areas, only buildings. (However, for some reason housenumbers are present in the districts west of Brighton, e.g Worthing)

If you want examples of this imagery being used, user Spiregrain has mapped significant sections of “Stratford New Town” in London using this imagery. I mapped some housenumbers in Sheerness using this imagery.

This should be very useful to many London mappers, and it would be great if people would start entering this data right away.

However, I think the best way of getting all this data into OSM is by using a tasking manager.

As of current, I don’t think there is a UK tasking manager, I think it is worth it create one just for this task.

The other advantage of a tasking manager is that you can mark “bad imagery”, in other words, you can mark tiles where construction has taken place, making the map useless.

If OSM UK can be contacted about implementing a tasking manager for this, that would be great.

The hardware landscape for street-level image capable cameras has improved substanially since Mapillary began. We'd like to share our latest thoughts on different camera types and the models we recommend.

Beach Street, Daytona Beach, FL, USA, is one of the prime commercial areas in Daytona Beach. Currently the city government is making extensive modifications to the street itself, moving it from two lanes each direction to one lane. It’s also adding parking and trying to convert the street from a through road to a destination.

And so it was disconcerting to notice that one entire block of Beach Street – from International Speedway Boulevard to Magnolia Avenue, had only one business listed, Net Works, Inc. It’s understandable why a computer company would be on OSM. After all, we’re all geeks, right.

But there were a lot of stores, etc., that were ignored on that block. Additionally, all the different storefronts and alleys were all combined into a single “building”. So I walked down the street this morning, adding in every open business between those two streets. I also separated out the buildings and left open the alley. It’s difficult to talk about attracting business if the map doesn’t show any place for the people to go.

Of course, now I have to deal with the delay time as the changes work their way slowly through the different OSM zoom levels. Right now (six hours later) the changes haven’t propagated through any zoom levels, although they do appear on the Edit screen if you feel the urge to see the changes. Oh well, we’ll see what it looks like in a few days.

I’m not 100% accurate on where the specific businesses are. However, the order is correct, and the difference should be minor.

This morning I also added a couple more businesses from my daily commute to work.

I’m in Iowa on a political campaign, but took last Sunday off to tour the six surviving covered bridges of Madison County. If you are interested in a virtual tour, check out the images I uploaded to Mapillary. I used a GoPro Hero 7 Black, newly acquired after the GPS function of the GoPro Hero 5 Black refused to work.

We assessed where we are and got a lot of good work OSMF Board Screen to Screen a couple weeks ago. One place where we have not moved as much as hoped is with diversity and inclusion. Diversity and inclusion was a big topic at the start of this year’s Board, we adopted a diversity statement and started a diversity and inclusion special committee (DISC) which had a couple good meetings. Then nothing. Why and what can be done to revitalize?

I take personal responsibility. I organized the first two meetings, but was hoping to see someone else step up to take charge on the effort. My background – white male techie from US/Western Europe – is very well represented in the OSMF, and I didn’t think it was best for the DISC to have me as the chair. On reflection, that was wrong, and I should take up the effort to bring dedicated people together and make sure they have what they need to channel limited time and energy effectively.

So I want to do three things.

First, I want to have calls with people from underrepresented groups and geographies in OSMF, hear about your involvement in OSM, what you’d like to do in OSM and OSMF (and certainly not only on diversity directly), and offer my guidance and help to find good places to contribute. OSM is hard to navigate, and I want to make direct personal effort. Many of you I have the privilege to know, many not yet. Please get in touch with me, or share my contacts with folks others.

Second, I want to revitalize DISC and simply chair it. To make it vital is again going to take personal outreach to people who have been involved, or could be involved, and find the best places again to focus. One area I think we should take up is trust and safety in our online communication spaces.

Finally, we’re about to have an OSMF Board election. I want to especially encourage underrepresented people to run – from outside North America and Europe, and women. If you think you have something to contribute, please step forward. I know it can be an uncertain move – if you have any doubts, please reach out too and I’m happy to talk about what’s it’s like.

Jeg vil gerne tilføje oplysninger til kortet over vores sommerhusområdet. Der er allerede et objekt med typen “Arkæologisk sted”. Men jeg kan ikke tilføje et objekt med den type. Er der en grund til det? Jeg har tre andre steder i vores området hvor der har været foretaget udgravninger.

I added a few miscellaneous items yesterday.

First, yesterday morning I added my gas station in DeLand. So now my RaceTrak is on the map.

Then, while I work I added one of our community centers to the map. I also added (separately) the tennis courts and the swimming pool. Since this was a work facility, there’s no guilt about doing that during the day.

I also made changes to the big hospital in Daytona Beach. The way it was mapped originally, a lot of the land on the other side of the street from the hospital was listed as hospital grounds. There’s an apartment building just constructed on that land, so I know it’s no longer hospital grounds. So I deleted that marker, but I added the Florida Health Care building which, while not associated with the hospital, is right across the street.

Finally, yesterday evening’s walk brought me by two Stetson dorms that weren’t tagged on the map. So I changed them from building to dorm and added the name to them.

Finally, apparently my application to the OSM Foundation was rejected because I used the wrong user name. Duh. So I resubmitted my membership application.

Można użyć serwisu Umap do korekty wizualnej jakiegoś zbioru danych (porównanie ich z danymi z OSM) w ten sposób, że do jednej warstwy importujemy dane z OSM, do drugiej nasze dane z innego źródła. Następnie dane w “naszej” warstwie można edytować i na koniec tę warstwę wyeksportować. I właśnie tej ostatniej czynności poświęcam niniejszy wpis.

Na początek wchodzimy do wyboru warstw:

Hello every body. My name is ESLAM and I am Egyptian My Home location

I must confess that in years of collaborating with more or less large projects, the worst community I have participated in is OpenStreetMap. There is no collaboration, the concept exists: this area is MY area so either you map as I say or rather you don’t map at all. So there are heterogeneous areas, some places with toponymy in dialectal form, others in Italian (I’m talking about Italy). For a moment I wanted to change all the toponymy of My 😅 area in dialect. But what’s the use? So I just make some changesets that I assume correct, if some other cartographer with a lot of degree tells me I was wrong, I revert. Simple, isn’t it? I only wish that if one criticizes me (even with rudeness) at least he would come down from the pedestal and tell me: you are wrong, these are the solutions. Instead it is not so. If I’m wrong tell me how to correct, saying it’s wrong is a non-constructive criticism. 🤔

I would like to share my experiences as a new mapper to OSM. I started mapping in August this year. I found the idea of providing open data to the community appealing. I would like to talk about my initial 2-3 months of mapping.

I have focussed on mapping the village near me called Ravenshead. A comparison image shows what it looked like from 2012. Between then and August 2020 very little changed. On the right shows the recent appearance, complete with addresses on houses. Overall I found the process to be slow but relaxing and satisfying. I would eventually like to speed up the process by looking at training a machine learning model to estimate roof locations, similar to Facebook, as a JOSM plugin, but trained on UK-style houses.

One of the things I had to wrap my head around was the lack of features on the main OSM map. Having used things like Google Maps I expected to be able to explore the OSM database through an intuitive map interface. I understand from a pragmatic point of view why the OSM map is not this way, but I feel it detracts from interest in the map. When showing a section of the map to someone not familiar with OSM I will tend to show them the layout in one website, and specific features in another. The best map I’ve found for interacting with is Map Carta which makes use of wikidata and wikipedia links to inform on objects on the map. I would like to see the main website’s map use a better user interface with the ability to select objects of interest to find out more information.

A big issue with inexperience I found was a lack of direction for rigorous process. Many times for tasks I found diverging advice. On one hand the freedom to map any way allows for fitting in different countries and cultures. On the other it makes it difficult to know how to handle tasks. One example is terrace houses (in England), the wiki article on terraces provides 3 alternative approaches to mapping a terrace. As a new mapper I feel I do not have the experience to make an informed decision on which approach to take. However, many places I want to map contain terraces. Therefor should I avoid mapping terraces, or risk incorrectly mapping them? I would like to see a streamlined approach to common tasks layed out so I and others with little experience can act without worrying that our mapping is in some way destructive or inferior to other methods.

Regarding mapping tools, aside from JOSM for editing, I have found StreetComplete to be a great tool for mapping. It finds a great balance between being intuitive and powerful. It has been great to help add purpose to my pandemic-based walks. For any new mappers I would highly recommend a recent diary post by IpswichMapper on the process for generally mapping buildings.

With regards to the community I feel as though some avenues are stale and create a sense of abandonment. The front page of the wiki was a great example of this. Until recently the last news was over 12 months ago. Some wiki article discussions have also been left alone for many years with a sense that some topics should be archived or marked as solved. This results in a sense that not many people are involved in community, and without obvious avenues for communication this can be the only impression available.

I am excited about continuing mapping. However, there is doubt in my mind on the longevity of the project brought about by a lack of addressing what I consider quite key issues (or at least lack of visibility of addressing these issues).

Well, that was an experience.

Yesterday I “ran” a 24K trail race. While I ended up walking a bunch of it, it did “finish” the race.

I came in last. (Correction: There was someone about an hour or so behind me. I didn’t know he was back there until I got home and looked at the results. It was probably dark before he finished the course.) If you’re interested, here’s the link to the actual run: https://connect.garmin.com/modern/activity/5728800211

However, I did make a few changes to the map based upon my run. Not a lot, but there were parts of the beginning of the run which were also visible on the photography that I marked. I also made a few other changes based on the run, so the map was updated.

A lot of the run was on unmapped mountain bicycle trails. They weren’t visible on the photograph, so I wasn’t comfortable putting them on the map. However, I did add the GPS trace to the database so if someone gets gung ho they can see what they can add. Enjoy.

My watch says I can’t run until Thursday morning, so I’m taking a bit of me time.

As written on the OSMF-Talk mailing list, I am proposing a resolution for the upcoming Annual General Meeting of the OSM Foundation on 12 December 2020. In order to get the proposal up for voting, I need support by at least 5 % of all members, i.e. about 80 members.

You can find the text and rationale in the OSMF-Talk archives.

If you want to support this proposal, please comment this diary entry with the openstreetmap.org account which is tied to your Foundation membership. If your membership record does not contain your username (or you are not sure), please send an email to osmf-agm20-sustainable@michreichert.de with your user name. Please use the email you use for your Foundation membership.

I will email the list of all supporters to the board after 4 November 2020 (UTC).

Supporting the proposal in this step does not mean that you will or have to vote in favour of it.

I would like to ask you to use the comment section of this diary entry only for the purpose outline above. Please use the OSMF-Talk mailing list to comment on the content of proposal instead.

This is a fright that turned to fun.

In my morning walk today I travelled along Shanowen Grove, and I took StreetComplete with me, adding building levels, addresses, building types and so on. On the last section of road I discovered one of the buildings to appear on StreetComplete as a tower.

Posting in the #osmIRL Telegram group I shared the screenshot. Dónal came to my rescue It turns out the building was specified to have 21 levels. Looking at the object history on JOSM later it turns out the levels were set by Tshedy see here. However, knowing Tshedy’s level of accuracy and the likelihood that “21” is a typo that was intended to be a “2”. This is very much in keeping with a similar “small”(but big) error in Melbourne.

StreetComplete is a great tool, especially where the basic building objects have been mapped, in a slow stroll along a street one can add serious detail, and the better the initial mapping the easier it is to see which objects require further details.

Last Friday, October 23, 2020, DINacon 2020 took place – unfortunately only virtually like all conferences during this time. DINAcon stands for “Digital Sustainability Conference” and is under the patronage of the CH Open association. At this event future-oriented projects and approaches from the Open Source and Open Data Communities, from public administration and the economy are presented, discussed and awarded.

The program also included a session on the “Public OSM Partnership” (POP Study) by Stefan Keller.

And again the DINAcon Awards were presented. The shortlist included the “Defikarte der Schweiz” (www.defikarte.ch) in the category “Community Award” and a JOSM Plugin in the category “Best Newcomer Award”.

And the winner is…

Finally the JOSM Plugin won in the category “Best Newcomer”! This category honors “Open Source projects that are not older than three years and offer exciting new approaches”.

The JOSM Plugin NeTEx Converter

The JOSM plugin “NeTEx Converter”, is a project for the JOSM editor, which collects and exports information about public transport – i.e. the infrastructure of stations – from OSM into this standardized XML structure. The NeTEx/XML file can then be further processed in various applications. Main developer is the student Labian Gashi who studies Computer Science in the masters program at HSR Rapperswil (now OST Campus Rapperswil). The work was supervised by Prof. Stefan Keller and specialists from the SBB.

It’s nice that another OpenStreetMap technology was awarded by this Open Source/Open Data conference. Already in 2019 the project OpenSchoolMaps won the trophy in the category “Best Open Education Project” (we reported here on SOSM.ch).

Dear colleagues,

OpenStreetMap Foundation is holding board elections soon. You would need to be a member to run. (That deadline has long passed).

Are you thinking of running? Why and why not? Please do you homework - talk with current or past board members. Let’s talk. Feel free to post a response here or reach out directly heatherleson AT gmail DOT com.

The OSMF Board has done great work this year. It is a relief to see such teamwork from the outside. I say this because it is something that is needed to support OSM.

For a global project, we continue to have a diversity and inclusion barrier in governance. I would like to encourage women and people from other regions to run for the OSMF Board.

And when the election nominations and voting begin - please consider what a true global board could be as part of your decision-making.

Thank you for all your passion for this project.
