ee.Geometry.LineString.intersection

  • Theintersection method returns the intersection of two geometries.

  • It takesright (another geometry), optionalmaxError, and optionalproj as arguments and returns a Geometry.

 Returns the intersection of the two geometries.

UsageReturns
LineString.intersection(right,maxError,proj)Geometry
ArgumentTypeDetails
this:leftGeometryThe geometry used as the left operand of the operation.
rightGeometryThe geometry used as the right operand of the operation.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullThe projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere.
