Luciano's Mapper's Challenge #3 - June, 2016

Posted by Luciano on 1 June 2016 in Korean (한국어)

Regarding the May challenge: I believe I failed - mostly due to lack of time. Nevertheless, I feel much happier with Tárrases now than I felt before - I have a better idea how it will finally look. You can read my updates at my "bliki."

Others have made better progress. Comment below or at your own diary entry or wiki sandbox (as Sarepava or BMSOUZA have done) about your results for May.

Luciano's Mapper's Challenge #3 - June, 2016

My new challenge is a focus on administrative divisions.

In fact, I've already done a lot of work on this, but I'd like to take it further, toward completion.

So first, an intro-level discussion of the administrative divisions of countries.

Most countries have administrative divisions - of many different names, levels, and functions. The list is very long: states, provinces, counties, municipalities, etc.

It's best to think in terms of levels:

  • 1st level: states (US, Mexico), provinces (Canada, South Korea), federal subjects (Russia)...
  • 2nd level: counties/parishes/boroughs (US), municipalities (Mexico), counties/cities (South Korea) ...
  • 3rd level: cities/townships (US), districts and townships (South Korea) ...

In the OSM tagging system, these are indicated by the admin_level tag. Each country uses the admin_level tag differently, both in the real world and in OGF (see here for the way some people have deployed admin_level in OGF).

The best practice is to set up relations for each administrative division. I have set up almost 500 administrative divisions in Mahhal for 1st and 2nd levels, and almost that number in the Ardisphere.

1st level divisions are complete in both countries, and not likely to change much. 2nd level divisions are mostly complete, too. What I really want to focus on is the 3rd level divisions, especially in the Ardisphere.

I have conceptualized a system with both "autonomous" cities and towns (i.e. with independent city and town legislatures and governments) and "non-autonomous" "municipalities," rather like townships in the US, which are really just ways for the next higher-level governments to organize community services (rural schools, clinics, roads, etc.).

There are roughly 70 2nd level divisions in the Ardisphere, and if I create between 10 and 20 towns, cities and municipalities for each 2nd level division (commune/county/shire/borough), then I will need between 700 and 1400 named 3rd level divisions (with corresponding relations) for the Ardisphere.

Compare this with, say, Argentina, which has a similar population (but much larger territory) to the Ardisphere. Argentina has about 360 2nd level divisions, and maybe 1000 3rd level divisions, but the category is incomplete. The US has approx. 3100 2nd level divisions and almost 20,000 "incorporated places" (3rd level divisions, but not complete coverage, i.e. that doesn't count rural townships).

My goal is to complete this schema for the Ardisphere, and create some fun multimaps to support the results (see my multimap of 2nd level divisions, here - it needs updating as there have been some changes).

The mapper's challenge:

  • Easy - work on "completing" your administrative divisions for your country, with correct relations, down to 1st level, including wiki lists and articles (perhaps stubs but with infoboxes in place)
  • Medium - work on "completing" your administrative divisions for your country, with correct relations, down to 2nd level, including wiki lists and articles (perhaps stubs but with infoboxes in place)
  • Hard - work on "completing" your administrative divisions for your country, with correct relations, down to 3rd level, including wiki lists and articles (perhaps stubs but with infoboxes in place)

    ((edit: of course, creating so many wiki articles is not a requirement!))

I am going to attempt some mix between "Medium" and "Hard" for the Ardisphere - I've already done "Easy."

If you follow my "recommended tagging practices" (alluded to here and here, but admittedly not very clear) I would even be happy to create a multimap for you for your divisions. The main point is that the multimaps are generated using only map-data and tags, so if you have the right info tagged in your relations, a multimap like I made for Commonia is a trivial matter of running the script.

Note that creating even only stub articles for 3rd level divisions would entail making maybe more than 1000 wiki articles. This may require my inventing OGF wiki's first "bot" - but I've been thinking about that, anyway.

Happy mapping.

I've yet to do much mapping on administrative areas yet. I've decided a basic system, which admin_level 3 is used for autonomous regions, namely the Isle of Reyston. Admin_level 4 will be used for regions. I haven't really decided to organise anything else as yet, but this will be a good time to do so.

I didn't really finish Alotes (the area were I worked on for previous month's challenge) but I'm happy with the result. If you want to see all what I did you can look on my flickr. I think I will try to do the Easy challenge this month and post updates on my flickr like last month. Maybe I will do the Medium too, but I think I will only do that if the Easy is finished.

Its a very hard task to me (all my adminstrative relations was not made by me, hehehe), but I will try.

PS: If possible, I would like to exclude my Luslandia of this challenge, because I still did not decide so much things about this country. But I will try create correct relations in Brasonia, Belgravia, Cariocas and Goytakanya!

Wow, a lot of things to do! I couldn't do the May challenge because I can't focus on anything for more than 5 minutes, but I really like doing administrative divisions. And I'd really love to learn how do a multimap, haha!!!

I have one question: for 2nd and 3rd level divisions, what's the recomended limit of maritime boundaries?

Comment from Luciano on 2 June 2016 at 14:02

@deltanz - I actually don't know the standard (if there is one) for maritime boundaries for 2nd and 3rd level. In Ardisphere, at some point very early I made an arbitrary decision to put maritime boundaries at 1 km for 2nd level - but there's no reason for this, and lately I've found the idea of using NO maritime boundaries for 2nd level, as I already do for 3rd level - mostly because this saves the need to create separate "land_area" relations for calculating land area. I just align the boundaries with the coast.

Mahhal is different, because I imagine there are feudal forces in the society that are still strong, and consequently, there are actual disputes between prefectures, municipalities and even towns over maritime boundaries, because of issues around who owns what marine fisheries. Thus I have been habitually extending all levels out to the 22km international.

@BMSOUZA - I followed your work with your updates at your sandbox on the wiki, and I'm really impressed with your work! It looks great. Don't worry about Luslandia - I am planning to focus on Ardisphere rather than Mahhal for this challenge.

So is this diffrent from using level 8 and level 6 in JOSM? I have set up some county boundries in the State of Reagan. I have also set up city/town boundries as well. I even made some "annexations" over the months as well.

I am working on the east coast now and I just set up boundry lines for the City of Averymouth. The city is a consoldiation of the Town of Newtown and the City of Averymouth to form on city, Averymouth. The city operates on a home rule city charter but it is not an independent city and is still related to Centmouth County.

This merger has created two distinct city centers with the courthouse remaining in the original county town(seat), Town of Newtown city center. Legislation has been passed to allow the city to have an independent municipal court with concurrent circuit court jurisdiction relating to criminal matters.

@No Way,

I suppose this hasn't been very clear about the connection to the "admin_level" tag in OSM/OGF... so here is a very quick summary (but also see this page). In common practice, the different administrative "levels" I discuss above (which is terminology from academic geography) match up to the OSM admin_levels as follows:

  • "Level 0" (in academic geography) :: nation :: "admin_level=2"
  • "Level 1" (in academic geography) :: state/province :: "admin_level=4"
  • "Level 2" (in academic geography) :: county/municipality :: "admin_level=6"
  • "Level 3" (in academic geography) :: city/town :: "admin_level=8"
  • "Level 4" (in academic geography) :: neighborhood :: "admin_level=10"

I might do the medium level. But a lot of the divisions beyond state level will depend on the placement of cities and towns, which aren't all in place yet. I have already divided Känton state into nine counties and a city, so perhaps it isn't so hard. I think I'm going to concentrate on getting plenty of rural landuse into the state as well.

I completed the challenge for May, mapping in central Shadze-Ma. Thanks Luciano for an interesting challenge that really helped me focus. I should probably do a separate diary entry about this place, to see what you all think about it, but in essence there are a scattering of rural islands with the town Yshon located on one of the more central islands.

I tried to get to a good level of detail in the area I picked (approx 10km x 10km with a lot of sea). At the start of the month the map was blank, it isn’t now. There are ferry routes to some of the outlying islands, which have different levels of administrative independence. Followers of Doonism form a majority in most of this part of Shadze-Ma, but Tlönism - a sort of religious sect - is strongly represented in North Karg.

It isn’t my intention to do the ‘boundaries’ challenge this month. Personally, as I’ve mapped more, I’m finding it better to make the administrative boundaries after other map features, so I’ll fill them in as I go along. The admin boundaries in Shadze-Ma are also complicated by a system that allows for high levels of autonomy, up to micro-state level, while preserving a municipal structure in some places. I think that this new challenge has already clarified some of these admin levels for me, so I may work through them again in the boundaries I’ve already created.

Meantime I’ll continue last month’s challenge for the next week or so to round out the details in this small area. Then I intend to wiki some of Shadze-Ma and move on to mapping some of its other islands.

@Sarepava and @Udi

Thanks for the updates, and I have been very impressed with your work. Of course, no worries if you prefer not to do this challenge, too - I find that having the admin-areas mapped out can give "structure" to subsequent, more detailed work, which is why I tend to do them earlier rather than later, but I have a lot of sympathy for saving those political divisions until later, too. Then again, one thing that is fun about working with this OSM-style data and having the relations all set up is that the specifics can be easily "rearranged" later - I've moved boundaries many, many times after creating them, so that they function sometimes as just guidelines for later mapping.

@Udi - I really like what you've done especially with Tlönism - someday I hope we can tie that back to a) freecyclopedianism and b) the Tlönic Civilization which is core to Ardisphere's ancient (pre colonial) history.

Why not do some mapping of your cities now and as they grow annex the areas or form new cities?

I don't think there's much I can do with administrative boundaries right now, so I plan to continue with last month's challenge and get this small area of Suvuma complete. :-)

Thanks Luciano. Of course the link should be to [Tlönianism](Tlönianism) - I'm sure we'll be able to work something out about its history and fit it in with the Ardisphere.

For Shadze-Ma I haven't planned out how the country will look yet, so I'm not sure where administrative divisions will be, or even if there are any big urban areas. I feel its more likely to develop as scattered towns and villages without any cities. Its a small island nation after all. I can only create the municipal boundaries after detailing the coastline because they follow this closely. I didn't see an international standard for 2nd level (county/island) maritime boundaries either - for Shadze-Ma they lie at 32 jalw from the mlws - I'll explain that later.

@ isleño - looking forward to it...

This looks like a great challenge.

I too find that thinking about this gives me structure for the rest of the map, to help not only draw infrastructure, but think about the history of the area and why things are where/as they are.

Ataraxia has had more of a top-down development, so I consider the first level (Ataraxia's regions, admin_level = 3) and second level (Ataraxia's provinces, admin_level = 4) are done.
The 2nd level is admin_level 4 mainly so that they will render at a higher level on the map, plus the provinces in Ataraxia have more power than counties in the US.

Next will be municipal cities and cantons within provinces as admin_level 6. Unincorporated places (lieux-dits) or neighborhoods may follow as admin_level 8.

This challange was a great motivation to do more municipality drawing around major cities. I completed a lot of the first-ring suburbs of Ataraxia and hope to have the structure of all of the municipalities around Ataraxia's big 3 (Ataraxia City, Oyonnax, Léopoldville) by the end of the month.

For maritime boundaries, I assumed there would be too much conflict and not enough resources to manage at the municipality or province level. The regional governments control coastal areas (except for the Perseus archipelago province, which gets a 1 km exclusive zone) while provinces control rivers and inland waterways.
