Looking at http://munin.openstreetmap.org/openstreetmap/smaug.openstreetmap/index.html the database has a lower load between 00:00 and 06:00 GMT. It would seem that that is the best time to run bots.

If the rails are removed to accommodate the road then you should not tag the abandoned railway at all as it is no longer there. If however you have a case of a railway on a road (like a tram) then you can tag the way as both a highway and a railway at the same time.

OSM is about mapping what is on the ground. According to the wikipedia article the area is administered by China. Wether or not other countries are claiming that area it is de facto Chinese. The boarder should then be placed on the line of actual control. Google have to be more political, but OSM can be factual.

But disputed areas are a problem in OSM. It is no technical problem with one area being in several multipolygons at once, but the problem is that someone might resort to vandalism. The best we can do is to remain as objective as possible.

It is allowed to put a name= tag on postboxes if you know the name. It is not allowed to copyright public knowledge, so if you know something without having to look it up there is no copyright on it. However you can not just memorize a work and then call it public knowledge.

In most cases you can assume that all post boxes in a country have the same operator (RM) so the operator tag can be omitted. You don't tag every road with an operator for the same reason.

That is why JOSM came with the option to filter data to edit. That way you can filter out all the messy shapes that would otherwise ruin your editing.

CloudMade have an extract that you can download OSM data for Jamaica at http://downloads.cloudmade.com/north_america/jamaica
They have similar extracts all over the world.

As I do not know what data type you want this in I can not help you converting it into a format that FSX understands. You could try the shapefiles as this is a widely supported file type that is a common standard for map data outside of OSM.

If you append /status to the tile url you get when it was last rendered. All tile urls are on the form http://c.tile.openstreetmap.org/[z]/[x]/[y].png

There is a T@H project that renderes the osmarender layer. Seehttp://wiki.openstreetmap.org/wiki/T@h for more info.

If you wonder about an import send the user a message. Often there are local mailing lists where imports gets discussed.

You could try any of the methods in osm.wiki/Shapefiles

But all these tools makes assumptions as osm does not use polegons but instead ways with special tags or relations.

I think that the mapnik name rendering rule does not filter any tags. If it has a highway=* and a name=* it gets rendered.

As for the addresses see osm.wiki/Addr

This looks great. I am stunned of the NED9 quality. You can even map buildings and roads from this.
Witch made me think; I am not an expert on US informational justice but isn't this data public domain? That means that we might use it for mapping.
After reading about NED I found out that it is actualy an ortogram. It is derrived from areal photographs for the use of rectification. Then where is the original ortphoto? And isn't that something we might trace?

I call fake. No way anybody have put this together for OSM. It looks like it is cut from another add.

Google goes to zoomlevel 19, mapnik to 18 and osmarender to 17.

This is a configuration on the server. But adding an extra zoomlevel doubles the space needed to store the tiles.
I don't know if the server got extra space, but it would be worth it. The speed of rendering is so fast today that i doubt it would be considered slow if we add another zoomlevel.

I hope that we one day could offer the most resolution of any map on the internet.

Great game but needs attribution.

This has been discussed lightly before.
The simple rule of thumb is that you can map addresses of houses (those are usually available from other maps as well), and businesses witch receive customers at that site. Do not start mapping phone numbers or names of the inhabitants.

As for the ID. Some people have made custom IDs witch states that they are mapping for OSM and what OSM is. But there is no officially issued IDs. A custom ID is preferred if you are afraid of getting in trouble for mapping.

And if he is a member of a gun club he should be familiar with what the law says about shooting other humans. Guns are effective because they are scary, not because they can kill.

The GPS traces are only shown to editors. If you wish to see the trace and draw the road on the map you have to go to the "Edit" tab and click "Show GPS traces (G)".

And now there are three.

Det er alltid kjekt å hjelpe til. For øvrig bruker eg http://sautter.com/map/?zoom=14&lat=58.50912&lon=5.82061&layers=B00000TFFFFF til å finne ut kvar det manglar detaljer.
Dersom du har lyst å bli meir engasjert i diskusjonar kan du sjå på maillista til kartgruppa i nuug.no

Dette ser jo ganske bra ut. Eg trur nesten Sirevåg er ein av dei mest komplette plassane i Norge. Men då snakkar eg om sentrum. Ser du litt utanfor sentrum er det mange vassdrag som ikkje er kartlagt. Men desse er lett å legge inn fra Landsat. Stå på, det ser bra ut.
