ee.Geometry.withinDistance

Returns true iff the geometries are within a specified distance.
UsageReturns
Geometry.withinDistance(right, distance, 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.
distanceFloatThe distance threshold. If a projection is specified, the distance is in units of that projected coordinate system, otherwise it is in meters.
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.

Code Editor (JavaScript)

// Define a Geometry object.
var geometry = ee.Geometry({
  'type': 'Polygon',
  'coordinates':
    [[[-122.081, 37.417],
      [-122.086, 37.421],
      [-122.084, 37.418],
      [-122.089, 37.416]]]
});

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

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

// Print the result to the console.
print('geometry.withinDistance(...) =', geometryWithinDistance);

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