Returns true if and only if the geometries are within a specified distance.
| Usage | Returns | LineString.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 LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);
// Define other inputs.
var inputGeom = ee.Geometry.Point(-122.090, 37.423);
// Apply the withinDistance method to the LineString object.
var lineStringWithinDistance = lineString.withinDistance({'right': inputGeom, 'distance': 500, 'maxError': 1});
// Print the result to the console.
print('lineString.withinDistance(...) =', lineStringWithinDistance);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(lineString,
{'color': 'black'},
'Geometry [black]: lineString');
Map.addLayer(inputGeom,
{'color': 'blue'},
'Parameter [blue]: inputGeom');
