ee.Feature.withinDistance

Returns true iff the geometries of two features are within a specified distance.
UsageReturns
Feature.withinDistance(right, distance, maxError, proj)Boolean
ArgumentTypeDetails
this: leftElementThe feature containing the geometry used as the left operand of the operation.
rightElementThe feature containing the 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.
