public static class PrecisionReducer

Methods

ReducePrecision(Geometry, PrecisionModel)

Reduces the precision of a geometry by rounding and snapping it to the supplied PrecisionModel.
The input geometry must be polygonal or linear.

The output is always a valid geometry. This implies that input components may be merged if they are closer than the grid precision. if merging is not desired, then the individual geometry components should be processed separately.

The output is fully noded (i.e. coincident lines are merged and noded). This provides an effective way to node / snap-round a collection of LineStrings.

Declaration

public static Geometry ReducePrecision(Geometry geom, PrecisionModel pm)

Parameters

Type	Name	Description
Geometry	geom	The geometry to reduce
