Asynchronously retrieves the value of this object from the server and passes it to the provided callback function.
| Usage | Returns | Geometry.evaluate(callback) | |
| Argument | Type | Details | this: computedobject | ComputedObject | The ComputedObject instance. |
callback | Function | A function of the form function(success, failure), called when the server returns an answer. If the request succeeded, the success argument contains the evaluated result. If the request failed, the failure argument will contains an error message. |
Examples
Code Editor (JavaScript)
// Define a callback function that prints a GeoJSON string.
var printGeoJSONString = function(geometry) {
geometry = ee.Geometry(geometry);
print(geometry.toGeoJSONString());
};
// Create a simple computed geometry.
var computedGeometry = ee.Geometry.Point(0, 0).buffer(10);
// Evaluate the callback function that asynchronously retrieves and prints
// the GeoJSON string representation of computed geometry.
computedGeometry.evaluate(printGeoJSONString);
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)
# The Earth Engine Python client library does not have an evaluate method for
# asynchronous evaluation of ee.Geometry objects.
# Use ee.Geometry.getInfo() instead.
