ee.Geometry.MultiLineString.withinDistance

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

Usage	Returns
`MultiLineString.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.

// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
   [[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
    [[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);

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

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

// Print the result to the console.
print('multiLineString.withinDistance(...) =', multiLineStringWithinDistance);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);

             {'color': 'black'},
