ee.Geometry.LineString.disjoint

  • The disjoint() method returns true only if the geometries do not share any points.

  • It is used to determine if two geometries are completely separate from each other.

  • The method can be applied to LineString geometries using the syntax LineString.disjoint(right, maxError, proj).

  • Optional parameters maxError and proj control the error tolerance and projection for the operation, respectively.

 Returns true if and only if the geometries are disjoint.

UsageReturns
LineString.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.

Examples

Code Editor (JavaScript)

// Define a LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);

// Apply the disjoint method to the LineString object.
var lineStringDisjoint = lineString.disjoint({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('lineString.disjoint(...) =', lineStringDisjoint);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(lineString,
             {'color': 'black'},
             'Geometry [black]: lineString');
Map.addLayer(inputGeom,
             {'color': 'blue'},
             'Parameter [blue]: inputGeom');
