ee.Geometry.MultiPoint.distance

  • Returns the minimum distance between a MultiPoint geometry and another geometry.

  • The distance calculation can be performed using a specified projection or in a spherical coordinate system (default, with distances in meters).

  • Optional parameters allow for specifying an error margin (maxError) for reprojection.

  • The result is a float representing the minimum distance.

 Returns the minimum distance between two geometries.

UsageReturns
MultiPoint.distance(right, maxError, proj, spherical)Float
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.
sphericalBoolean, default: falseIf 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 MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);

// Define other inputs.
var inputGeom = ee.Geometry.Point(-122.090, 37.423);

// Apply the distance method to the MultiPoint object.
var multiPointDistance = multiPoint.distance({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('multiPoint.distance(...) =', multiPointDistance);

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