Editor de código (JavaScript)
// Define a LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);
// Apply the projection method to the LineString object.
var lineStringProjection = lineString.projection();
// Print the result to the console.
print('lineString.projection(...) =', lineStringProjection);
// Display relevant geometries on the map.
