Re: [emergency] Circle and Polygon

Claude -

GML is not a mapping standard! GML is a standard, grounded in a variety of 
ISO 19*** series standards, for 
encoding/expressing/communicating/transporting 
geographic/location/geospatially enabled content. Now, in terms of 3D, I 
would strongly encourage you to check out LandGML 
(http://www.transxml.org/GML+Experiment/Resources/261.aspx and 
(http://www.opengeospatial.org/initiatives/?iid=133) and CityGML 
(http://www.ikg.uni-bonn.de/sig3d/docs/Gi4Dm_2005_Kolbe_Groeger.pdf), both 
application profiles of GML 3.1.

In terms of SVG, there are any number of tools that do GML to SVG for 
rendering. Some are free, some are for fee.

Cheers

Carl
