Method Detail

qualityFixForSections

public static Collection<Feature> qualityFixForSections(Collection<Feature> secs)

Perform a number of operations on network sections to ensure a clean planar graph can be built from them.

Parameters:

secs -

Returns:

ensureNodeReduction

public static Collection<Feature> ensureNodeReduction(Collection<Feature> secs)

ensureNodeReduction

public static Collection<Feature> ensureNodeReduction(Collection<Feature> secs,
                                                      NodeReduction.NodeReductionCriteria nrc)

checkSectionsIntersection

public static void checkSectionsIntersection(Collection<Feature> secs)

Check some linear features do not intersect along linear parts. This should be avoided to build a planar network.

Parameters:

secs -

fixSectionsIntersection

public static Collection<Feature> fixSectionsIntersection(Collection<Feature> secs)

Fix intersection issue. If sections are fully overlapped by other, they might be removed. The list of remaining sections with non-empty geometries is returned. These geometries might be multilinestring. To get only simple geometries, use FeatureUtil.getFeaturesWithSimpleGeometrie

Parameters:

secs -

Returns:

fixSectionsIntersectionIterative

public static Collection<Feature> fixSectionsIntersectionIterative(Collection<Feature> secs)
