I have made some changes to the map data, but when I look at the map, it doesn't show my edits. Have I done something wrong? |

The OpenStreetMap-data is used to create many different maps, often by different people and available on different websites. There are maps you can view with your browser and maps for other programs or even mobile devices (like Garmin maps). Every one of these maps can be very different:
When you talk about 'the map', you may mean the 'Mapnik'-layer on OpenStreetMap.org. That one should be updated every minute, but you still have to keep in mind that not everything is shown there. If you checked the points above and you still think your changes should appear, you may indeed have done something wrong. Please consider doing the following:

Very nice explanation! If you are interested in a more in depth explanation of the process of how the main map in the view tab on OpenStreetMap.org gets updated and why sometimes it is very up to date and sometimes not so much, see http://help.openstreetmap.org/questions/178/how-often-does-the-main-mapnik-map-get-updated

Assuming that you're worried about the Mapnik view on openstreetmap.org and you've verified that your data has made it into the database (tick the "data" box, for example), you may be suffering from a stale cache in your browser. You can solve this by following these steps: Load up the map view you've edited, click permalink, then force a full refresh of your browser. In FireFox this is done with CTRL + F5. This action clears your cache and reloads any javascript, as such it will download the latest tiles. If it still looks wrong, you might want to request that a tile is rerendered. To do so, right click on the tile in question and choose "view image" or equivalent. This will give you something like: http://b.tile.openstreetmap.org/14/8138/5495.png add /dirty to the end and it will be queued for rerendering: http://b.tile.openstreetmap.org/14/8138/5495.png/dirty Wait a few minutes and force reload your browser again, the newly rendered tile should appear. Most importantly, however, I wouldn't worry too much about the rendering; the important thing is that your edits make it to the database, not the fact that you may have to wait a few minutes for them to display on openstreetmap.org. This does not appear to have any effect on the cyclemap layer which is what I'm primarily interested in. My changes are being updated on the standard map, but the cyclemap is not being updated.

The cycle map layer uses Andy Allen's opencyclemap tiles. He says that "The map is updated every week (on a Thursday or Friday, normally)".

Updates to coastlines may be extremely long to be reported in OSM's Mapnik renderer (it takes weeks if not months), even if there were enormous errors corrected (like unconnected coastlines: one example, corrected since 2 weeks, is in Britanny, the most western peninsula in France, where the Atlantic Ocean does not fill an enormous block). Other renderers are not affected (MapQuest, OpenCycleMap, OpenSeaMap...). All other updates are made visible on OSM's Mapnik maps in a few minutes (a bit more for low resolution zoom levels : it may take one day or two when viewing a continent).
