C# Class SharpMap.Converters.WellKnownText.GeometryToWKT

Outputs the textual representation of a GeoAPI.Geometries.IGeometry instance.

The Well-Known Text (WKT) representation of Geometry is designed to exchange geometry data in ASCII form.

Examples of WKT representations of geometry objects are: Geometry WKT Representation A Point POINT(15 20)
Note that point coordinates are specified with no separating comma. A LineString with four points: LINESTRING(0 0, 10 10, 20 25, 50 60) A Polygon with one exterior ring and one interior ring: POLYGON((0 0,10 0,10 10,0 10,0 0),(5 5,7 5,7 7,5 7, 5 5)) A MultiPoint with three Point values: MULTIPOINT(0 0, 20 20, 60 60) A MultiLineString with two LineString values: MULTILINESTRING((10 10, 20 20), (15 15, 30 15)) A MultiPolygon with two Polygon values: MULTIPOLYGON(((0 0,10 0,10 10,0 10,0 0)),((5 5,7 5,7 7,5 7, 5 5))) A GeometryCollection consisting of two Point values and one LineString: GEOMETRYCOLLECTION(POINT(10 10), POINT(30 30), LINESTRING(15 15, 20 20))
