ee.Geometry.LineString.distance

Returns the minimum distance between two geometries.

Usage	Returns
LineString.distance(right, maxError, proj, spherical)	Float

Argument	Type	Details
this: left	Geometry	The geometry used as the left operand of the operation.
right	Geometry	The geometry used as the right operand of the operation.
maxError	ErrorMargin, default: null	The maximum amount of error tolerated when performing any necessary reprojection.
proj	Projection, default: null	The 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.
spherical	Boolean, default: false	If true, the calculation will be done on the unit sphere. If false, the calculation will be elliptical, taking earth flattening into account. Ignored if proj is specified. Default is false.

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.Point(-122.090, 37.423);

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

// Print the result to the console.
print('lineString.distance(...) =', lineStringDistance);

// 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');
