Class LineDissolver

Dissolves the linear components from a collection of Geometrys. into a set of maximal-length LineStrings in which every unique segment appears once only. The output linestrings run between node vertices of the input, which are vertices which have either degree 1, or degree 3 or greater.

Syntax

public class LineDissolver

Remarks

Use cases for dissolving linear components include generalization (in particular, simplifying polygonal coverages), and visualization (in particular, avoiding symbology conflicts when depicting shared polygon boundaries).

Constructors

LineDissolver()

Creates an instance of this class

Declaration

public LineDissolver()

Methods

Add(Geometry)

Adds a Geometry to be dissolved. Any number of geometries may be added by calling this method multiple times. Any type of Geometry may be added. The constituent linework will be extracted to be dissolved.

Declaration

public void Add(Geometry geometry)

Parameters

Type	Name	Description
Geometry	geometry	geometry to be line-merged

Add(IEnumerable<Geometry>)

Adds a collection of Geometries to be processed. May be called multiple times. Any dimension of Geometry may be added; the constituent linework will be extracted.

Declaration

public void Add(IEnumerable<Geometry> geometries)

Parameters

Type	Name	Description
IEnumerable<Geometry>	geometries	the geometries to be line-merged

Dissolve(Geometry)

Dissolves the linear components in a geometry.

Declaration

public static Geometry Dissolve(Geometry g)

Parameters

Type	Name	Description
Geometry	g	the geometry to dissolve

Returns

Type	Description
Geometry	the dissolved lines

GetResult()

Gets the dissolved result as a MultiLineString.

Declaration

public Geometry GetResult()

Returns

Type	Description
Geometry	the dissolved lines
