AI-generated Key Takeaways
-
getInfo()
retrieves the value of a ComputedObject (like a Geometry) from the Earth Engine server. -
Requests can be made synchronously (blocking) or asynchronously (non-blocking) using a callback function.
-
Asynchronous requests are generally preferred to avoid UI freezes and are typically made using
evaluate()
instead ofgetInfo()
. -
This method returns the computed value of the object, such as coordinate data for a Point.
-
Examples are provided in JavaScript and Python demonstrating how to use
getInfo()
and display results.
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.
Usage | Returns |
---|---|
Point.getInfo(callback) | Object |
Argument | Type | Details |
---|---|---|
this: computedobject | ComputedObject | The ComputedObject instance. |
callback | Function, optional | An optional callback. If not supplied, the call is made synchronously. |
Examples
Code Editor (JavaScript)
// Define a Point object. var point = ee.Geometry.Point(-122.082, 37.42); // Apply the getInfo method to the Point object. var pointGetInfo = point.getInfo(); // Print the result to the console. print('point.getInfo(...) =', pointGetInfo); // Display relevant geometries on the map. Map.setCenter(-122.085, 37.422, 15); Map.addLayer(point, {'color': 'black'}, 'Geometry [black]: point');
import ee import geemap.core as geemap
Colab (Python)
# Define a Point object. point = ee.Geometry.Point(-122.082, 37.42) # Apply the getInfo method to the Point object. point_get_info = point.getInfo() # Print the result. display('point.getInfo(...) =', point_get_info) # 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') m
