		double	borderSimplificationMaxLength,
		unsigned int	minFeaturePolylineSize,
		unsigned int	maxClusterSize,
		double	maxSurfaceVariance
	)

inline

Constructor

Parameters

borderSimplificationMaxDistance	Maximum error for polyline simplification
borderSimplificationMaxLengthPercent	Maximum length for an edge in the simplified polyline. This prevents oversimplification in planar tiles.
minFeaturePolylineSize	Minimum number of connected edges in a sharp feature polyline to consider it during processing
maxClusterSize	Maximum cluster size
maxSurfaceVariance	Maximum cluster variation value

Constructor

Parameters

borderSimplificationMaxDistance	Maximum error for polyline simplification per zoom
borderSimplificationMaxLengthPercent	Maximum length for an edge in the simplified polyline per zoom. This prevents oversimplification in planar tiles.
minFeaturePolylineSize	Minimum number of connected edges in a sharp feature polyline to consider it during processing
maxClusterSize	Maximum cluster size per zoom
maxSurfaceVariance	Maximum cluster variation value per zoom
