示例
代码编辑器 (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.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(lineString,
{'color': 'black'},
'Geometry [black]: lineString');

[null,null,["最后更新时间 (UTC):2025-07-26。"],[],["The `projection()` method is applied to a geometry object, specifically demonstrated with a `LineString`. This method returns the projection of the geometry. In the examples provided, a `LineString` is defined, and the `.projection()` method is called upon it. The resulting projection is then printed. Geometries are also displayed on a map, with the `LineString` shown in black. This process can be applied using javascript or python.\n"],null,[]]
