Detailed Description

Simplifies a linestring (sequence of points) using the standard Douglas-Peucker algorithm.

Member Function Documentation

void geos::simplify::DouglasPeuckerLineSimplifier::setDistanceTolerance ( double nDistanceTolerance )

Sets the distance tolerance for the simplification.

All vertices in the simplified linestring will be within this distance of the original linestring.

Parameters

nDistanceTolerance the approximation tolerance to use
