ee.Geometry.Point.withinDistance

Returns true if and only if the geometries are within a specified distance.

Usage	Returns
Point.withinDistance(right, distance, maxError, proj)	Boolean

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.
distance	Float	The distance threshold. If a projection is specified, the distance is in units of that projected coordinate system, otherwise it is in meters.
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.

Examples

Code Editor (JavaScript)

// Define a Point object.
var point = ee.Geometry.Point(-122.082, 37.42);

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

// Apply the withinDistance method to the Point object.
var pointWithinDistance = point.withinDistance({'right': inputGeom, 'distance': 500, 'maxError': 1});

// Print the result to the console.
print('point.withinDistance(...) =', pointWithinDistance);

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