Next weekend (June 13-15) the SotM-EU (“State of the map - Europe”), the conference of the European Openstreetmap community, will be held in Karlsruhe, Germany.

The cool thing is, Johannes and I will be giving a talk about Opengeofiction on Friday June 13 at 11:00 a.m. local time (9:00 UTC):

If everything works as planned, you can watch a livestream of our talk:

(I guess there will also be recorded videos available afterwards, if you don’t have the time to watch it live.)

I’ve sketched out some “forest” areas to propose a chain of mountains running across Gobrassanya. I think working out terrain early on is good way to establish patterns for future cities, roads and other infrastructure to develop realistically.

I also think it’s good to establish large areas of low density (in this case, mountains) because I think these maps are more realistic when they have a clear contrast between populated areas (lowlands, cities, coastlines, etc) and unpopulated areas (mountains, forests, deserts, etc).

(So for example, fewer cities and roads in the mountains, more cities and roads in the lowlands, just like in real life. In this scenario the proposed A50 and A70 corridors would probably be red highways, and the western part of the proposed A5 would not exist.)

In any case feel free to discuss here. Thanks!

The LMC (Latina Metro Compañia) has published a new map of the metro-system of the city. The backside of the plan - including the lines in the inner city with more details - you can see here = www.horstbu.de/metrolatina.png

[O.k. - not all stations are set and not all stations have a name. That is, becaus the city too is “work in progress”]

There are some express-lines - so each second train of line # 1 north of “Universidad” is an express-train. Between “Artado” and “Universidad” the green line # 7 stops only at “Espana”-railway-station and in the southern part the grey line # 8 goes direkt from “Estacion Sur” to “Fabio Megontes”. The trace of lines # 6 and 7 north of “Universidad” was formerly the trackbed of the northern railway, which now terminated in the main-station (Estacion Central).

The northern part of line # 10 is only in action, if there are the fairies (“Messe”/”Feria”) or if they play in the national stadium. Line # 11 in his northeastern part is in construction still. This line works in two sections 11a and 11b (Ponte Kennedy - Almolario and Est. Sur - Estadio Nacional), so that in the middle part the service is denser.

Between “Independencia” and “Guëll” you see three lines ( ## 1, 5 and 6). They all run - with 6 tracks - in the old area of the eastern fortification of the old town. Between “Guëll” and “Torquez” too are three lines (## 1, 2 and 12) with 6 tracks. Here formerly was a part of the port of Latina, which is now the park of the Esplanade-Boulevard along the shore. The main seagoing ships now start at Saguset-City, where is deeper water.

If you are a friend of soccer-sport, you will find easy all importand places in town.

Have fun with that map.

In the case of a continent flooding, you’re all - especially the more experienced users - called upon to fix it. That’s a case where I consider it justified to make an edit in another user’s territory. It can be quite difficult however to find the exact location of the problem. To help with that, I created the following page which displays nodes where the coastline is broken in some way:

http://opengeofiction.net/util/coastline_info.html

(Click on a marker in that map to see more information about the related node.)

Explanation: see this article for a comprehensive description of the requirements for coastline data. It follows that any node in a coastline way must be either

  • a member of exactly one such way, either as an interior point or as its combined start and end point (if the way is closed) or
  • a member of exactly two ways, where it is the start point of one and the end point of the other

Nodes that do not meet this condition are displayed on the map. Obviously they don’t always cause a rendering problem, but in the case of a major flooding you will probably find the problematic location among them.

This is what I do: http://i.imgur.com/ny0ltfr.png

The left-hand window is my JOSM editor. The right-hand window is a similar area in the real world (viewed in OSM) and I’m making sure that both are at a similar zoom level.

In this case I’m creating FunLand Khaiwoon, using Hong Kong Disneyland as a model. By “model” I mean I’m trying to make sure that the buildings are roughly the same size, the parking lot is roughly the same size, the little car race track is roughly the same size, the theme park as a whole is roughly the same size, etc.

This seems to work pretty well for me. I’ve used the same technique for airports, seaports, industrial areas, etc.

Anyone have other tips and tricks they’d care to share?

EDIT: There is now a tool that does this much more easily —OGF scale helper!

at “view”-mode you have a little skala left down on the screen. In “edit”-mode there is really nothing. Not helpful.

So I have seen, on my screen at zoom 16 (200m) that this 200 m are 34 millimeters on screen. How long this 200 m are on your screen, may differ logically. So I made a little strip of paper and a mark at 17 mm for 100 m, at 34 mm for 200 m and so on. That is for zoom 16. For zooms 17 (100 m) and 18 (50 m) you can set the meters too at your markers.

O.k. - is not perfect, but better as nothing. And by the time you get a feeling for the meters at the scale, in which you work. In doubt you set your paper-ruler softly at the screen

Some mesures = Great churches normally not longer then 80 m, a soccer-field 100 * 67m , one Block in Manhattan / New York 60 * 240 m, one block in the “Eixample” of Barcelona 148 * 148 m.

There is a very helpful tagging guide at the OpenStreetMap site which means I have been manually adding details and features to the map which are not shown in the sidebar. One particularly nice result of this is that I can now label mountains and hills which helps give a sense of topography to the landscape. Indeed, the entire layout of a country depends on the location of highlands and flatlands, since these dictate where watercourses run and so where cities are founded and how transport links will connect them.

Here are two images that will show you where your territory would be if it was on planet earth with the same geocoordinates as in Opengeofiction. These are screenshots from an early stage of the recent server migration when I had imported the map data but not yet replaced the shapefiles for coastline rendering. Just thought this might be interesting. (To see the full size, right click on the image and select “View Image” from the menu).

Its beautiful to see the updates within 5 minutes. It makes my editing go much smoother. I combined both North Pretany and the South Pretanic Kingdom into one megacountry called The Kingdom of Pretany. I am excited to get some new neighbors to link to and collaborate with. Feeling lonely to my south and east and my neighbor to the north is never home.

In some cities it is usual, to give a name for a street only once in the whole town (p.e. Hamburg / Germany). In other great cities a street-name can given twice or more often, but only once in a defined area (p.e. Berlin / Germany).

In Khaiwoon we need a lot of street-names. So I think, a street-name could be used twice or more, but only once in a suburb. What do you mean?

General impression ~ Description sounds brilliant, tx Thilo.

Should make things easier to use for me to use (I think/hope).

Some initial queries:-

1]. Almost all of the planet is currently shown ‘under water’ in the VIEW screen. There are just a few white ‘islands’ showing… Is this something that we - users - have to ‘fix’ ourselves, and if so, how do we do this?

2]. My offshore islands: Their outlines have all disappeared, leaving just their inter-state boundaries sitting in the ocean. How to ‘fix’, please?

3]. Text display size: My vision is imperfect and I find that the names for things on the map are a little too small for me to be able to see clearly. How can they be magnified say, 20-25%?

4]. I NEED to be able to see the settlement nodes/names at most map-representation magnifications, but the ‘smaller settlements’ all disappear as I zoom-out. How may I prevent this, as this is a very important factor for me? (Without having to mark them all up as ‘cities’!)

5]. I am SERIOUSLY struggling to think of a way to join my settlements with highways, etc. ~ because at the ‘Editing Magnifications’ I cannot tell where &/or in what exact direction the ‘next settlements lie. Is there a ‘trick’ to this, or some method of (say) just joining the settlement nodes with straight lines (that may later be individually edited)?

6]. I need to show physical geographic features like hills, mountains, moors, valleys, vales, etc. Please can you advise where I might find facilities to suit (this, I appreciate is simply a matter of my severe inexperience!).

7]. I’m entirely unsure about ‘LAYERS’ and their purposes/uses & best practice ~ please could you advise?
