ee.Geometry.Polygon.bounds

  • The Polygon.bounds() method returns the bounding rectangle of a geometry.

  • It can take optional arguments for maxError and proj.

  • The result of Polygon.bounds() is a Geometry object.

  • Examples are provided in both JavaScript and Python to demonstrate usage.

 Returns the bounding rectangle of the geometry.

UsageReturns
Polygon.bounds(maxError, proj)Geometry
ArgumentTypeDetails
this: geometryGeometryReturn the bounding box of this geometry.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullIf specified, the result will be in this projection. Otherwise it will be in EPSG:4326.

Examples

Code Editor (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 bounds method to the Polygon object.
var polygonBounds = polygon.bounds();

// Print the result to the console.
print('polygon.bounds(...) =', polygonBounds);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(polygon,
             {'color': 'black'},
             'Geometry [black]: polygon');
Map.addLayer(polygonBounds,
             {'color': 'red'},
             'Result [red]: polygon.bounds');
