Si quieres contribuir a OSM usando datos del IGN, te recomiendo que uses el editor JOSM con la capa del PNOA del IGN.

Si usas Potlatch, seleccionas la vía, luego un nodo de esa vía, y le das al icono de las tijeras.

Si usas JOSM, seleccionas una vía y el nodo, y usas la herramienta de separar vía (P).

Go ahead. Just remember to provide attribution - see http://wiki.openstreetmap.org/wiki/Legal_FAQ#I_would_like_to_use_OpenStreetMap_maps._How_should_I_credit_you.3F : " If you are using OpenStreetMap tiles (e.g. Mapnik or Osmarender/tiles@home), we request that your credit reads at least "(c) OpenStreetMap (and) contributors, CC-BY-SA". "

No cost. At all. But we'll be grateful if you improve the data in your area, of course.

Please have a look at the milestone proposal here: http://wiki.openstreetmap.org/wiki/Proposed_features/Milestones

Depende del editor que uses (si editas a través de la web, estás usando Potlatch).

Échale un vistazo a esta página del wiki, donde vienen los manuales de cada editor: http://wiki.openstreetmap.org/wiki/Comparison_of_editors

@Wikigraphist:
If you want to set up your own separate database, there are a lot of tools to keep it up-to-date...

e.g. set up a PostgreSQL DB and a (customized) Mapnik renderer on top of it. Then, load an initial planet with Osmosis, then set up Osmosis to load the hourly planet diffs into your DB.

Your DB will be, at worst, one hour behind the OSM one. If you really, really care about up-to-dateness, you can set up minutely diffs, so your DB will be just one or two minutes behind the OSM one.

I'm thinking about CloudMade's Style Editor. As a company, they have the resources to render customized maps in a jiffy. It's run by SteveC and NickB, I do think you should talk to them. See: http://cloudmade.com/products/style-editor

Failing that, custom PostgreSQL server and custom Mapnik WMS. Ask the talk-dev mailing list.

Teóricamente, al hacer calzadas, hay que hacer el centro de la calzada (es decir, el carril central en cada caso). Teóricamente.

El problema que me ha parecido ver es que las líneas se juntan cuando van en una determinada dirección, y se separan cuando van en otra. Eso suele ser bastante significativo de que el trazado está mal.

Por cierto, ¿estás en la lista de correo?

No te preocupes por los carriles, no es lo más importante. Estamos trabajando a nivel de calzada, así que de momento no importa.

Un par de cosas, sin embargo: deberías intentar que la distancia entre calzadas sea constante (que ahora mismo no lo es en el tramo al que te refieres), para que queden paralelas, y mantener los mismos tags para las dos calzadas.

Ya nos veremos por Madrid en algún momento. :-)

No sé, yo sigo sin tener claro que se pueda usar el catastro o el PNOA tranquilamente - tanto la oficina del catastro como el IGN/CNIG tienen un punto de vista muy propio sobre el "uso comercial" y el "uso no comercial" y la licencia actual de OSM.

Hi, James, this is ivansanchez from Madrid :-)

First of all, thanks for tracing all that huge chunks of Madrid!

About the boundaries, I do know that the IGN publishes the boundaries for provinces, municipalities and cities, and (at least) the province boundaries have a license which is near public domain (so, no problem). I don't know about the exact license terms of the municipalities and city voundaires, but I can ask.

Could you please pass by the talk-es mailing list, or write to me, so we can see how to import that data? (I don't check the diaries very often)

The main mapnik layer re-renders every wednesday. The osmarender layer usually takes a day.

Could you subscribe to the talk-es mailing list? There'll be some people visiting Sevilla in a couple of weeks, and maybe you would like to meet them.

1) In my case, it started as a hobby, but quickly turned into copyleft activism. You could say that my motivations for spending time in OSM are philosophical, as I do believe that maps should be free as in freedom (and will fight for that!).

Anyway I think that, as the map becomes complete, less and less people will see OSM as a hobby, and more and more will see OSM as a cost-effective solution for fresh geodata. The tools and technique for spreading OSM to non-geeks are not ready (yet), but I do believe that in a few years OSM *will* displace navteg/teleatlas data. This will lead to more people using OSM because it's just cooler/cheaper/better, not because it's fun.

2) Beer!!

IMHO, the first reason to attend mapping parties (or SotM) is to socialize. Second reason is to improve or learn new mapping techniques, or discuss technical aspects face-to-face.

A mapping party may be a good technique to kick-start the map of some place, but there is (from my point of view) no sense of hurry: the map will be done, eventually.

Cheers, Iván

There should be a file called "mkgmap.jar" - you'll need Java to run it, and you'll need to run it from a console. mkgmap does not have a graphical interface.
