ee.Geometry.MultiPolygon.getInfo

  • MultiPolygon.getInfo() retrieves the value of a MultiPolygon object from the Earth Engine server and returns it as a GeoJSON object.

  • This method can be used synchronously or asynchronously, with the asynchronous approach being preferred to avoid blocking other code execution.

  • evaluate() is recommended for asynchronous requests, while getInfo() can be used for synchronous requests.

  • Code examples demonstrate using getInfo() in both JavaScript and Python environments to retrieve and display MultiPolygon data.

Retrieves the value of this object from the server.

If no callback function is provided, the request is made synchronously. If a callback is provided, the request is made asynchronously.

The asynchronous mode is preferred because the synchronous mode stops all other code (for example, the EE Code Editor UI) while waiting for the server. To make an asynchronous request, evaluate() is preferred over getInfo().

Returns the computed value of this object.

UsageReturns
MultiPolygon.getInfo(callback)Object
ArgumentTypeDetails
this: computedobjectComputedObjectThe ComputedObject instance.
callbackFunction, optionalAn optional callback. If not supplied, the call is made synchronously.

Examples

Code Editor (JavaScript)

// Define a MultiPolygon object.
var multiPolygon = ee.Geometry.MultiPolygon(
    [[[[-122.092, 37.424],
       [-122.086, 37.418],
       [-122.079, 37.425],
       [-122.085, 37.423]]],
     [[[-122.081, 37.417],
       [-122.086, 37.421],
       [-122.089, 37.416]]]]);

// Apply the getInfo method to the MultiPolygon object.
var multiPolygonGetInfo = multiPolygon.getInfo();

// Print the result to the console.
print('multiPolygon.getInfo(...) =', multiPolygonGetInfo);

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