Syntax
public static class GeometryFromWKT
Remarks
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)) |
