返回几何图形的 GeoJSON 类型。
示例
代码编辑器 (JavaScript)
// Define a Point object.
var point = ee.Geometry.Point(-122.082, 37.42);
// Apply the type method to the Point object.
var pointType = point.type();
// Print the result to the console.
print('point.type(...) =', pointType);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(point,
{'color': 'black'},
'Geometry [black]: point');
Python 设置

进行交互式开发,请参阅
Python 环境页面。
import ee
import geemap.core as geemap
Colab (Python)
# Define a Point object.
point = ee.Geometry.Point(-122.082, 37.42)
# Apply the type method to the Point object.
point_type = point.type()
# Print the result.
display('point.type(...) =', point_type)
# Display relevant geometries on the map.
m = geemap.Map()
m.set_center(-122.085, 37.422, 15)
m.add_layer(point, {'color': 'black'}, 'Geometry [black]: point')
