Luciano's Mapper's Challenge #6 - September, 2016 - GETTING AROUND

Posted by Luciano on 3 September 2016 in Korean (한국어)

For my challenge last month, "What's in a name?" (August 2016), I added about 1600 names to my city state of Tárrases, advancing from about 2800 names to a current total of 4400.

I fell far short of my revised objective of 10000 names. I feel sad because of that, but... I was very busy outside of OGF, with "real life," so that's my excuse. I will continue working on it.

This challenge did not seem to be very popular. I guess for a lot of people, names are not an important part of their geofictional undertakings. Certainly the popularity of maps with unnamed streets and other features in our world indicates that for many, names are an afterthought.

I know a few people worked on it, though. Feel free to post your results in the comments, below, or with your own diary.

Thinking about Public Transportation

One of my main interests in geofiction is in the area of public transportation infrastructure: trains, subways, buses, etc. It has always been fascinating to me. But after a few efforts in that direction with my metropolis at Villa Constitución, I have mostly been intentionally avoiding placing public transportation infrastructure, because I feel like to do it correctly, it needs to be built "in response to" the pre-existing geography. It doesn't make sense to make a detailed, elaborate subway system, as I did in Villa Constitución, when the city itself is really just the skeleton of a city, without well-conceived history or neighborhoods or topography, etc.

From a technical standpoint, I'm very proud of my RUTA-VC multimap and other work (like the Green Line wiki article) done for that city's subway system. Here is a screenshot from last year.

The advantage of using the OSM route relation infrastructure is clear if you examine a well-built route. Let's look at a more-or-less random example from RUTA-VC, such as VC's Commuter Rail Line N31, which connects the downtown to the south coast islands in a great arc:

You can use OSM route relations for highways, too, as in Ardisphere's RN 31, which runs the length of the country along its eastern border:

Anyway, I think route relations are very cool, and fun to build, and they can help you to be organized in your approach. They can be used for riverboat and ferry networks, too, and I eventually plan to build those.

However, at this point I plan to eventually delete almost all of VC's public transit, and start over, after some big changes to the city itself, including a more organic and historically oriented pattern of growth.

In my work on Tárrases, however, I think I'm about ready to start building some public transit in detail. Tárrases, being a smallish city (about 400,000 inhabitants), will only have a limited, recently built tram (light rail) system with 2-3 lines maximum. Most of the public transit will be buses (maybe 20-30 routes), along with a taxi-van system (like the Mexican "pesero" system - shared taxis that run on fixed routes).

I want to build a nice, detailed, multimap-based route map, as I did for RUTA-VC.

Luciano's Mapper's Challenge #6 - September, 2016 - GETTING AROUND

The challenge this month is to focus on public transit - subways, commuter rail, buses, etc. But not just in the wiki! Lots of people have done great work in the wiki for public transit, but that's not the focus of this challenge.

The OSM platform we use for OGF has a lot of excellent tagging options for public transit (see here). So let's try to use them to get well-defined routes, with stops and everything. I am going to try build the route system on the OGF map and use the results to create a semi-automatically-generated bus-route multimap for Tárrases.

  • Advanced challenge - Build a complete system for a city, including route relations for all the routes. Try to build a multimap of your public transit system, or, if you're more comfortable with drawing programs (I'm not), make an image map instead.
  • Easier challenge - Build a couple of routes of a system

Happy mapping for September!

Hahaha!!! Its perfect to me right now!!! Looks like we talk before you create this Challenge, hehehe...

I have the same thoughts: Is hard creating a public trasnport system AFTER creating all the streets. Last month I did not start the August Challenge before, exactly because I was re-creating a lot of streets and tramways, due to the Transurb Slovech correct relations to buses and tram routes.

Actually, it is a new rule I will ever follow when creating cities or towns.

Well, my intention about Transurb Slovech is including metropolitan routes too, but I will not get it right now because I will not re-do the metropolitan towns right now, but at least the municipal bus and tram routes, I can do...

Lets go!!!!

While I'd like to plan out the transport routes in Sadiemarkt, I think I'll work in a smaller city (or cities as it may be) given how sparse most of the capital is as of yet.

I've already created some metro lines in my capital city, Balonis City, but I'm not so sure whether they are realistic or not. I could use some feedback: http://opengeofiction.net/#map=12/-16.0725/126.3754

My absolute favourite topic ;D I've started organizing some subway lines in Pyingshum as routes, in the hope to one day map them in wiki articles. It's not 100% accurate as I only include stations and line segments in the route relations (and not the exact stopping position for example), but it's good enough. I still have to figure out the most convenient way to describe routes with branches though.

Btw, could you go into a little more detail as to how exactly you tag your route relations and what roles you give to the elements? i'm also confused about why there are apparently two standard versions of public transportation routes on OSM, and just went with the latter one, but are there any advantages to using the old one?

I've been thinking about buses in Dunwic for a while so this is the impetus I needed to start mapping out some routes to areas of the city which are 'finished'. At the moment I'm just mapping the routes, not stops. I will get around to adding bus stops eventually.

You can see the routes I've completed on the wiki article.

@niels - I think you're off to a good start, but basically I think you're in the same situation I was in about 2 years ago, when I was building Villa Constitución's subways but I still hadn't made much progress on many other aspects of the city. My advice would be to hold off on subway work until more of the city is filled in.

@Leowezy - I confess that I am not exactly following either of the standard versions. I think my work is more similar to the newer (more complicated) tagging system, but I have made some adaptations and customizations that make it possible for me to use my Perl scripts to get my multimaps in a "semi-automated" way. Because of that, in fact I don't want to recommend my system, because I'm breaking the standard. I guess my goal is to stay as close to the new standard as possible, but if I need to do something differently to support my script, I do. I make more use of route_master relations, and I have some non-standard tags that contain "intersecting route" information at individual stations. Having said that, if you're interested, you are free to download parts of Villa Constitución and take a look.

@Myrcia - as usual, your extremely detailed and methodical approach is a great example. I can only hope to do as well.

Now would be a good time to revisit the question of an OGF Transport layer. There are lots of options out there for rendering public transport routes in OSM and I think it would be really beneficial to do something similar for OGF.

Examples:

http://openptmap.org/ http://xn--pnvkarte-m4a.de/

I don't know if we'd have to create a whole new render or use one of the existing ones. Last time I bought this up people were concerned about licensing but the two renders I've put up there are both under Creative Commons.

For me this is one of the big things OGF is missing.

@Myrcia: I completelly agree with you!

@Luciano Thank you for your response :) I think I'll let the subway now for what it is and modify and delete parts when I've made more progress in the city.

@Myrcia Yes!! It would be very cool to have a Transport layer on OGF.

Well, I got my first bus routes laid down. And... I discovered the main disadvantage to the "new" schema for bus routes vs the "old" schema for bus routes: the "new" schema doesn't render on our current map. I confess I didn't actually realize this - I've only done rail routes until now - this is my first attempt to do a fully systematic bus route. Rail routes seem to render OK under the "new" schema, but bus routes... nothing. So now I understand better everyone's talk, above, about wanting a transport layer. I guess we have to hope for a new server at some point, so we can support more different layers.

My problem is that my scripts rely on the new schema. So now I am in the position of "doubling" the schemas - I am labelling all my bus stops, etc., using both new and old schemas. That way they render (old schema) but also will allow me to get clear data for automated tables and multimaps later (new schema).

I've made a light rail and 3 bus routes - you can find them here:
