ee.Geometry.MultiLineString.disjoint

  • The disjoint method returns true if the geometries do not intersect.

  • It takes a GeoJSON Geometry, an optional error margin and an optional projection as input.

  • The geometries are considered disjoint if they do not share any points.

  • This method can be applied to any geometry object in Earth Engine.

 Returns true if and only if the geometries are disjoint.

UsageReturns
MultiLineString.disjoint(right, maxError, proj)Boolean
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.

// Define a MultiLineString object.

// Define other inputs.

// Apply the disjoint method to the MultiLineString object.

// Print the result to the console.

// Display relevant geometries on the map.
