AI-generated Key Takeaways
-
getInfo()
retrieves the value of a ComputedObject (like a BBox) from the Earth Engine server, returning the result as a JavaScript object. -
This method can be used synchronously (blocking other code execution) or asynchronously (using a callback function for non-blocking behavior).
-
Asynchronous requests are generally preferred to prevent UI freezing and can be achieved by providing a callback function to
getInfo()
or using theevaluate()
method. -
Example code snippets are included for both JavaScript (Code Editor) and Python (Colab and geemap).
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 |
---|---|
BBox.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 BBox object. var bBox = ee.Geometry.BBox(-122.09, 37.42, -122.08, 37.43); // Apply the getInfo method to the BBox object. var bBoxGetInfo = bBox.getInfo(); // Print the result to the console. print('bBox.getInfo(...) =', bBoxGetInfo); // Display relevant geometries on the map. Map.setCenter(-122.085, 37.422, 15); Map.addLayer(bBox, {'color': 'black'}, 'Geometry [black]: bBox');
import ee import geemap.core as geemap
Colab (Python)
# Define a BBox object. bbox = ee.Geometry.BBox(-122.09, 37.42, -122.08, 37.43) # Apply the getInfo method to the BBox object. bbox_get_info = bbox.getInfo() # Print the result. display('bbox.getInfo(...) =', bbox_get_info) # Display relevant geometries on the map. m = geemap.Map() m.set_center(-122.085, 37.422, 15) m.add_layer(bbox, {'color': 'black'}, 'Geometry [black]: bbox') m
