@turf/combine - npm Package Versions

4.5.0

🚀 New Modules

• @turf/clusters Takes a set of points and partition them into clusters using the k-means clustering algorithm. (PR https://github.com/Turfjs/turf/pull/787 - Author @stebogit )

• @turf/boolean-disjoint Boolean-disjoint returns (TRUE) if the intersection of the two geometries is an empty set. (PR https://github.com/Turfjs/turf/pull/805 - Author @rowanwins)

• @turf/boolean-contains Boolean-contains returns True if the second geometry is completely contained by the first geometry. The interiors of both geometries must intersect and, the interior and boundary of the secondary (geometry b) must not intersect the exterior of the primary (geometry a). Boolean-contains returns the exact opposite result of the @turf/boolean-within. (PR https://github.com/Turfjs/turf/pull/797 - Author @rowanwins)

• @turf/boolean-crosses Boolean-Crosses returns True if the intersection results in a geometry whose dimension is one less than the maximum dimension of the two source geometries and the intersection set is interior to both source geometries. Boolean-Crosses returns t (TRUE) for only multipoint/polygon, multipoint/linestring, linestring/linestring, linestring/polygon, and linestring/multipolygon comparisons. (PR https://github.com/Turfjs/turf/pull/796 - Author @rowanwins)

• @turf/boolean-clockwise Takes a ring and return true or false whether or not the ring is clockwise or counter-clockwise. (PR https://github.com/Turfjs/turf/pull/789 - Authors @morganherlocker @stebogit)

• @turf/clone Prevents GeoJSON coordinates from being mutated, similar to JSON.parse(JSON.stringify(geojson)). Only cloning the coordinates can be 3x-20x faster than the parse + stringify approach. (PR https://github.com/Turfjs/turf/pull/824 - Author @DenisCarriere)

🏅 New Features/Enhancements

• convertArea Converts a area to the requested unit. (PR https://github.com/Turfjs/turf/pull/821 - Author @wnordmann)

4.4.0

🚀 New Modules

• @turf/polygonize Polygonizes (Multi)LineString(s) into Polygons. Implementation of GEOSPolygonize function (geos::operation::polygonize::Polygonizer). (PR https://github.com/Turfjs/turf/pull/767 - Author @NickCis)
• @turf/transform-rotate Rotates any geojson Feature or Geometry of a specified angle, around its centroid or a given pivot point; all rotations follow the right-hand rule. (Issue https://github.com/Turfjs/turf/issues/747 - Author @stebogit)
• @turf/transform-translate Moves any geojson Feature or Geometry of a specified distance along a Rhumb Line on the provided direction angle. (Issue https://github.com/Turfjs/turf/issues/747 - Author @stebogit)
• @turf/transform-scale Scale a GeoJSON from a given point by a factor of scaling (ex: factor=2 would make the GeoJSON 200% larger). If a FeatureCollection is provided, the origin point will be calculated based on each individual Feature. (Issue https://github.com/Turfjs/turf/issues/747 - Author @stebogit)
