The Earth Engine ui module is only available through the JavaScript API CodeĮditor. Results of expensive, large, or long running computations. In general, the best practice is toĪnd once complete, import them into a new script for further analysis.Ĭaution: Calling getInfo() in your script will block execution.Īdditionally, requests for a lot of data or expensive computations can return an error Note that getInfo() is a synchronous operation, meaning execution of expressionsįollowing the getInfo() call are blocked until the result is returned to the client.Īdditionally, requests for a lot of data or expensive computations can return an error and/or # Print image object WITH call to getInfo() prints image metadata. # Print image object WITHOUT call to getInfo() prints serialized request instructions. Printing an Earth Engine object in Python prints the serialized request for the object,Ĭall getInfo() on Earth Engine objects to get the desired object from the server Start an export task: task.start() Check export task status: task.status() Note: Tasks started from the Python API will also appear in the Tasks Region= my_geometry, # an ee.Geometry object. Task = ee.(image= my_image, # an ee.Image object. The following example demonstrates exportingĪn ee.Image object. Query a task's status byĬalling the status() method on it. Started by calling the start() method on a defined task. Pass parameter arguments as you would with the JavaScript API, minding theĭifferences noted in the syntax table above. Module, which provides an interface to theįunctions.
Py_date = (ee_date.getInfo()/1000.0) Convert client-side date to ee.Date:Įxporting data with the Python API requires the use of the ee.batch Import datetime Convert ee.Date to client-side date: Y = fun(**) or y = fun(**arg_dict).ĭefine and manipulate client-side date objects with theĭatetime module. I.e., prepend two asterisks to the function input dictionary: Function arguments provided as a keyword arguments dictionary must be.
Named functions when complex mapping operations are required. Lambda functions, which accept only a single expression. Anonymous function mapping is achieved via.Common syntax differences between JavaScript and Python Property When working with the Python API relative to the JavaScript API. The following table includesĪ list of the common syntax differences you'll encounter server)Ĭan vary because of language syntax differences. Initialize the API: ee.Initialize() Syntaxīoth the Python and JavaScript APIs access the same server-side functionality,īut client-side expressions ( learn more about client vs. In general, authentication for local installations is a one-time step that generates a persistentĪuthorization token, while VM services such as Colab, limit the token's lifetime. It must be imported and initialized forĮach new Python session and script: import eeĪuthenticate to the Earth Engine servers: ee.Authenticate() How you obtain authentication credentials may vary depending on yourĮnvironment.
