Notes on WKT Support

Using addWKT() and addWKTToWKT() functions custom geometries can be added as a layer.

These WKT primitives are supported :

• POINT
• LINESTRING
• POLYGON
• TRIANGLE
• MULTIPOINT
• MULTILINESTRING
• MULTIPOLYGON
• POLYHEDRALSURFACE
• TIN
• GEOMETRYCOLLECTION

Please specify geometries with a Z component for 3D data. Data without a Z component will be projected on an imaginary ground plane, calculated using the current photo position and camera height.

Some examples can be found here : http://en.wikipedia.org/wiki/Well-known_text

For multipoint geometries, only the syntax where each point is enclosed by brackts is supported.

• Supported :

  MULTIPOINT ((10 40), (40 30), (20 20), (30 10))

• NOT Supported :

  MULTIPOINT (10 40, 40 30, 20 20, 30 10)
