ee.Geometry.LinearRing.getInfo

  • getInfo() retrieves the value of a ComputedObject (like a LinearRing) from the Earth Engine server.

  • It can be used synchronously (blocking other code) or asynchronously (using a callback function).

  • Asynchronous requests are preferred to avoid UI freezes and evaluate() is generally recommended over getInfo() for this purpose.

  • The method returns the computed value of the object as a JavaScript Object when called.

  • Examples demonstrate its usage with a LinearRing in both JavaScript and Python within the Earth Engine Code Editor and Colab environments.

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
LinearRing.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 LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

// Apply the getInfo method to the LinearRing object.
var linearRingGetInfo = linearRing.getInfo();

// Print the result to the console.
print('linearRing.getInfo(...) =', linearRingGetInfo);

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

Python setup

See the Python Environment page for information on the Python API and using geemap for interactive development.

import ee
import geemap.core as geemap

Colab (Python)

# Define a LinearRing object.
linearring = ee.Geometry.LinearRing(
    [[-122.091, 37.420], [-122.085, 37.422], [-122.080, 37.430]]
)

# Apply the getInfo method to the LinearRing object.
linearring_get_info = linearring.getInfo()

# Print the result.
display('linearring.getInfo(...) =', linearring_get_info)

# Display relevant geometries on the map.
m = geemap.Map()
m.set_center(-122.085, 37.422, 15)
m.add_layer(linearring, {'color': 'black'}, 'Geometry [black]: linearring')
