also, to experienced mappers

So basically, if you add RSS, achavi would completely replace now abandoned new OWL?

Нет, читаю всё на http://blogs.openstreetmap.org :) Вполне вероятно, что такси, хотя зачем им остановки...

Ты ему в личку написал? Он не покусается, с большой вероятностью :)

I spoke at SotM EU 2014 about mapping behind the wheel: http://sotm-eu.org/en/slots/2

Rostranimin, thanks for your suggestions. Of course I'm writing from a position of a skilled programmer who's spent some days struggling with Mapnik and most of tools surrounding it. It's very hard to change my point of view :)

The task is quite simple: getting a raster (or vector) image of a map. Currently there are two options: download tiles (256×256 images that web maps are built from) and stitch them (just a bit harder than making a screenshot, see BigMap), or load OSM data into PostgreSQL, install Mapnik and make it render an area for you. Since Mapnik is a library, not a user-oriented program, you need an external tool to which you feed geographic bounds and image size. Nik4 is such tool: basically, after going through all steps to install and load everything, you can switch your brain off and just feed Nik4 numbers, or even URLs, and it would give you images.

Georeferencing is just an icing; most users don't need that. Just making plain images of maps was a hard task — before Nik4.

In case it wasn't mentioned, try OsmAnd. It's great.

Can you process multiple styles with this? For example, to answer "it doesn't render with the default OSM style, but try switching to Humanitarian layer".

Ты сообщил в трекер?

Ты в осмерском аду!

Thanks! I've restructured the stub page a bit. For now I don't know what to add there, besides links to the announcement and github. We'll see.

Удачи! :)

Of course, hard to argue with that. Sadly I don't see even tickets in github tracker on that: closest thing is layered svg (which tilemill still does not produce). I've opened issue 2229.

All other renderers show the area correctly. This is possibly related to administrative borders rendering.

I know the page is too long — try this illustrated tutorial.

In this political map I've manually updated data in a PostGIS database, and rendered a patch for Crimea, which I then overlayed on top of a world map. Much visual effect comes just from different colouring, which is easy to create using one of TileMill's example projects.

Правильно - в Крыму, но о Крыме. Только что посмотрел, поправил в заметке, спасибо.

Отличный и подробный текст, спасибо. Из поправок — что вместо building:material чаще используется building:cladding.
