範例
程式碼編輯器 (JavaScript)
// Define a LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);
// Apply the coordinates method to the LineString object.
var lineStringCoordinates = lineString.coordinates();
// Print the result to the console.
print('lineString.coordinates(...) =', lineStringCoordinates);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(lineString,
{'color': 'black'},
