@turf/line-intersect
Advanced tools
@turf/line-intersect is a module from the Turf.js library that provides geospatial analysis tools. This specific module is used to find the intersection points between two or more lines. It is useful in various geospatial applications, such as mapping, urban planning, and geographic information systems (GIS).
Find Intersection Points
This feature allows you to find the intersection points between two lines. In the code sample, two lines are defined, and the `lineIntersect` function is used to find their intersection points.
const turf = require('@turf/turf');
const line1 = turf.lineString([[0, 0], [2, 2]]);
const line2 = turf.lineString([[0, 2], [2, 0]]);
const intersections = turf.lineIntersect(line1, line2);
console.log(intersections);
JSTS is a JavaScript library of spatial predicates and functions for processing geometry. It is a port of the Java Topology Suite (JTS). JSTS provides more comprehensive geometry processing capabilities compared to @turf/line-intersect, including operations like buffering, union, and difference.
Martinez Polygon Clipping is a library for performing boolean operations on polygons, such as intersection, union, and difference. While it focuses on polygon operations, it can also be used to find intersections between line segments within polygons, offering more specialized functionality compared to @turf/line-intersect.
Takes any LineString or Polygon GeoJSON and returns the intersecting point(s).
Parameters
line1
(Geometry | FeatureCollection | Feature<(LineString | MultiLineString | Polygon | MultiPolygon)>) any LineString or Polygonline2
(Geometry | FeatureCollection | Feature<(LineString | MultiLineString | Polygon | MultiPolygon)>) any LineString or PolygonExamples
var line1 = turf.lineString([[126, -11], [129, -21]]);
var line2 = turf.lineString([[123, -18], [131, -14]]);
var intersects = turf.lineIntersect(line1, line2);
//addToMap
var addToMap = [line1, line2, intersects]
Returns FeatureCollection<Point> point(s) that intersect both
