Can anyone show me how to create a lake and name it, presumably it will be similar for a woodland area or industrial buildings etc?--still very very much a newbi!--thanks |

If you edit in potlatch2 and you have a good Bing image of the lake (that's the aerial image you can select in the editor) and you have some traces to check the alignment then you can draw around the lake as before just make sure the last node joins the first this will reveal lake as among the water features for you to choose. see http://wiki.openstreetmap.org/wiki/Lakes I understand there is a need to trace lakes and islands in opposite directions to set water to left or right of line hopefully some body will add that information for us. linked question http://help.openstreetmap.org/questions/11214/two-separate-boundaries-do-not-make-an-island

Here's some info regarding direction of way for coastlines which logically is relevant. So have the land to left and water to right so go anti clock around an island and clockwise around a lake. http://wiki.openstreetmap.org/wiki/Tag:natural%3Dcoastline

Only coastline needs to stick to the land-on-the-left rule. Everything else can be drawn in either direction. If you want to draw a lake with islands you need to use a mulipolygon relation to draw the island as a polygon within the lake polygon.

In Potlatch, creating a lake involves drawing a way that closes on itself, you can then set it as a lake by selecting the drop-down menu under "water". The Basic and Details tabs will then let you set a name. Woodlands and Industrial Areas (industrial buildings are more complicated) are similar: you'll find Forests under "nature" (although the default tag choice appears incorrect IMO) and industrial land under "Landuse". |
Thanks everyone for the info.
