Returns the result of subtracting the 'right' geometry from the 'left' geometry.

LineString.difference(right, maxError, proj)Geometry
this: leftGeometryThe geometry used as the left operand of the operation.
rightGeometryThe geometry used as the right operand of the operation.
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.

// Define a LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);

// Apply the difference method to the LineString object.
var lineStringDifference = lineString.difference({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('lineString.difference(...) =', lineStringDifference);

// Display relevant geometries on the map.
