AI-generated Key Takeaways
-
getInfo()
retrieves the value of a ComputedObject (like a LineString) from the Earth Engine server. -
Requests can be made synchronously (blocking other code) or asynchronously (preferred for responsiveness).
-
Asynchronous requests are recommended and can be achieved using
evaluate()
or providing a callback function togetInfo()
. -
The method returns the computed value of the object as an object, for example, the coordinates of a LineString.
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 |
---|---|
LineString.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 LineString object. var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]); // Apply the getInfo method to the LineString object. var lineStringGetInfo = lineString.getInfo(); // Print the result to the console. print('lineString.getInfo(...) =', lineStringGetInfo); // Display relevant geometries on the map. Map.setCenter(-122.085, 37.422, 15); Map.addLayer(lineString, {'color': 'black'}, 'Geometry [black]: lineString');
import ee import geemap.core as geemap

# Define a LineString object. linestring = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]) # Apply the getInfo method to the LineString object. linestring_get_info = linestring.getInfo() # Print the result. display('linestring.getInfo(...) =', linestring_get_info) # Display relevant geometries on the map. m = geemap.Map() m.set_center(-122.085, 37.422, 15) m.add_layer(linestring, {'color': 'black'}, 'Geometry [black]: linestring') m
