What exactly are you trying to do? There are a lot of things you can do with polygons.

I just need a little example of polygon code to view it.

Here's the simplest possible polygon, a triangle:

<way id="1" version="1" user="test" uid="1" changeset="1" timestamp="...">
  <nd ref="1" />
  <nd ref="2" />
  <nd ref="3" />
  <nd ref="1" />
  <tag k="building" v="yes" />
</way>

A polygon is just a way where first and last nodes are the same, and where the tags indicate that it is an area. (The same structure with a tag of junction=roundabout would not be interpreted as an area.)

More complex polygons - those with holes or where the outline is made up of several ways - are modeled using the multipolygon relations which is a bit of a misnomer since it is also used for polygons that are not "multi".

1	Usually you can click on any polygon in the map of www.openstreetmap.org while selecting the view data layer. From there it is possible to select a polygon and from the details page you can view the XML. answered 02 Apr '12, 21:19 frabron 361●1●4●11 accept rate: 16%
