示例
代码编辑器 (JavaScript)
// Define a Polygon object.
var polygon = ee.Geometry.Polygon(
[[[-122.092, 37.424],
[-122.086, 37.418],
[-122.079, 37.425],
[-122.085, 37.423]]]);
// Apply the type method to the Polygon object.
var polygonType = polygon.type();
// Print the result to the console.
print('polygon.type(...) =', polygonType);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(polygon,
{'color': 'black'},
'Geometry [black]: polygon');

[null,null,["最后更新时间 (UTC):2025-07-26。"],[],["The `type()` method determines the GeoJSON type of a given geometry, returning a string. When applied to a Polygon object, it identifies the object as a \"Polygon\". The method takes a Geometry object as input. Example usage is shown in both JavaScript and Python, where a Polygon is defined, the `type()` method is called, and the resulting type is printed. The examples also demonstrate how to display the geometry on a map.\n"],null,[]]
