API Changelog

2024-10-28

Python API (v1.2.0)

• Dropped support for Python 3.8 now that it is end-of-life.
• Added ImageCollection.count(), a static method that returns the number of images in the collection.

2024-09-09

Web API

• Added new algorithms to find the point on one feature or geometry that is closest to another feature or geometry: ee.Geometry.closestPoint(), ee.Geometry.closestPoints(), ee.Feature.closestPoint() and ee.Feature.closestPoints()

2024-09-03

Web API

• BACKWARD INCOMPATIBLE Fixed signed int8 for ingest and export. For ingest, the system used to treat signed int8 as unsigned int8 with negative values mapped to [128..255]. Those values are now correctly assigned their negative value. For export, the system used to cast int8 to int16, while correctly storing the negative values. Export will now write an int8 with the correct values.

Python API (v0.1.419)

• Fixed a bug where the quota project wasn't being set when authenticating using the notebook auth mode. After this change, users must have the Service Usage Consumer role (roles/serviceusage.serviceUsageConsumer) on the authentication project in order to use the notebook authentication mode. See the Earth Engine Authentication and Initialization guide for more details.

2024-07-24

Web API

• BACKWARD INCOMPATIBLE Reduced the maximum allowable header size of a GeoTIFF (produced by the ee.Image.loadGeoTIFF() algorithm or by CreateAsset as a COG-backed asset) from 32mb to 10mb. This change does not affect COG-backed assets with headers >10mb created prior to this date.

• Fixed a bug that caused GeoTIFF exports with cloudOptimized set to true to fail if the output GeoTIFF was larger than 4gb. Earth Engine will now always produce BigTIFF regardless of the value of cloudOptimized.

2024-07-16

Code Editor

• Fixed a bug where specifying minWidth and minHeight style properties on ui.Slider widgets had no effect. Setting these properties now allows for horizontal sliders narrower than the default minWidth of 50px, and vertical sliders shorter than the default minHeight of 100px.

2024-07-10

Web API

• Fixed a bug that caused GeoTIFF exports to ignore skipEmptyTiles if formatOptions.cloudOptimized was true.

2024-06-07

Web API

• BACKWARD INCOMPATIBLE Changed the way that the ee.Image.loadGeoTIFF() algorithm and COG-backed assets select lower resolution overviews if a GeoTIFF is missing pyramid levels. Earth Engine will now resample to the nearest higher-resolution overview instead of the closest overview regardless of resolution. This does not affect GeoTIFFs that are not missing intermediate pyramid levels.

2024-05-10

Web API

• Added support for overwrite parameter in Export.table.toBigQuery() method, which allows for control over overwriting data in already existing destination table.

2024-04-18

Web API

• Added support for the Bray-Curtis distance metric (braycurtis) to ee.Classifier.smileKNN().

2024-04-03

JavaScript API (v0.1.397)

• Fixed a bug in ee.data.listAssets() and ee.data.listImages() that caused only a single page of results (up to 1000 entries) to be returned. This now matches the Python implementation, which returns all results by default. To return a single page in either client, specify a pageSize value. The documentation in both the JavaScript and Python clients has been updated to reflect this behavior.

Python API (v0.1.397)

• Updated the error handling logic for HTTP requests to convert requests.exceptions.ConnectionError and requests.exceptions.ChunkedEncodingError to httplib2-like errors. In some cases, these errors were not being treated as retryable; now, the retry logic should behave properly for these errors.

• Added ee.data.createFolder to the Python client to match the JavaScript client. Note that the force and callback parameters are not supported.

2024-03-25

• Found and fixed a reprojection error which affected the correctness of some Earth Engine results from Mar 7, 2024 to Mar 13, 2024. See the announcement for more details.

2024-03-13

Code Editor

• Added a new code annotation and warning message in the script editor to highlight usage of deprecated Landsat Collection 1, which needs to be converted to Collection 2 as soon as possible.

2024-03-06

Web and Python API (v0.1.393)

• Added priority to Earth Engine Export batch tasks. This feature is currently only available when using a Cloud project that is registered for paid Earth Engine access.

• Added Geometry.fromS2CellId() and Geometry.fromS2CellToken() for working with S2 (http://s2geometry.io/) polygons.

2024-01-31

JavaScript API (v0.1.388)

• Migrated the authorization workflow in the JavaScript library from the Google API Client Library for JavaScript to Google Identity Services.

Python API (v0.1.388)

• Added __init__() for docstrings and argument type annotations to Array, ConfusionMatrix, DateRange, Model, Projection, and Reducer.

2024-01-18

Web API

• BACKWARD INCOMPATIBLE Changed the behavior of ee.data.listOperations to return only tasks created in the currently selected Cloud project, including those started by other users. For more details, visit the developer announcement.

Python API (v0.1.386)

• Added __init__() for docstrings and argument type annotations to ErrorMargin and Join.

2024-01-10

Python API (v0.1.385)

• Fixed authentication issues for the gcloud auth application-default calls to login and set-quota-project. Added the cloud-platform scope to the default scopes used by ee.Authenticate().

• Added __init__() for docstrings and argument type annotations to PixelType.

2023-12-08

JavaScript and Python API (v0.1.383)

• Added Export.classifier.toAsset and ee.Classifier.load for exporting and loading saved ee.Classifier.smileCart and ee.Classifier.smileRandomForest classifiers. The exported classifiers will be visible and managed just like existing Earth Engine assets. More details are available at our supervised classification and our export reference page.

Python API (v0.1.383)

• Updated ee.Authenticate() and ee.Initialize() to support colab mode, added new gcloud mode for remote machines (which makes the --quiet flag no longer necessary), and introduced localhost mode. ee.Initialize() now uses ambient google.auth.default() credentials if present. ee.Authenticate(force=True) forces a refresh, but by default will now reuse existing credentials. See the auth page for the revised documentation.

• Switched from setup.py to pyproject.toml for building and installation.

  • Drops support for installing with distutils.

• Removed opt_ keyword for parameters, with backwards compatibility with existing scripts that use opt_ arguments. Note that some parameters needed to be renamed after removing opt_ since they conflict with Python keywords:

  • ee.Collection.limit(): opt_property was converted to prop
  • ee.Image.expression(): opt_map was converted to map_
  • ee.Filter(): opt_filter which was converted to filter_

• Added ee.Blob(url) to allow type checking of the url argument and catch strings that don't start with gs:// when possible on the client side.

JavaScript API (v0.1.383)

• Added getMapId() to ee.Image, ee.ImageCollection, ee.Feature, and ee.FeatureCollection to match the Python client. Marked getMap() as deprecated.

2023-11-29

Web API

• Fixed a bug that prevented the download of large (more than 1000 elements) collections.

• Fixed a bug that sometimes caused missing pixels in images that cross the antimeridian (longitude 180°).

2023-11-15

Python API (v0.1.379)

• Added a long-lived requests.Session object so that calls to Earth Engine can share a connection pool. This should increase performance and stability.

• Disallowed complex, rational, and integral numbers in ee.Number().

• Added workload tag support to ee.data.getPixels().

2023-11-01

Python API (v0.1.377)

Earth Engine Apps

• Fixed linked drawing tools in Apps so that geometries are synced between two drawing tools with setLinked(true).

2023-09-14

JavaScript API (v0.1.369)

• Fixed ee.data.getOperation() and ee.data.getTaskStatus() error handling. Operations that complete with an error are now returned as Operation objects that include error details, instead of throwing an exception.

Python API (v0.1.369)

• Migrated Python client library from deprecated https://accounts.google.com/o/oauth2/token to https://oauth2.googleapis.com/token for OAuth 2.0 authentication.

2023-09-07

JavaScript API (v0.1.368)

• Added documentation to ee.data.newTaskId() and ee.data.startProcessing() to clarify unsubmitted versus submitted task IDs, and fixed ee.batch.ExportTask.start() to return the submitted task ID.

2023-08-24

Python API (v0.1.366)

• BACKWARD INCOMPATIBLE Fixed construction of an ee.Date object from a tzinfo-aware datetime object. Naive datetime objects are still treated as UTC.

2023-08-17

Web API

• BACKWARD INCOMPATIBLE Added support for multidimensional arrays in Export.table.toBigQuery(). The BigQuery array format changed from ARRAY<INT64|FLOAT64> to STRUCT<ARRAY<INT64>, ARRAY<INT64|FLOAT64>>, where the first parameter is dimensions and the second parameter is values.

2023-08-09

Code Editor

• Launched Project-owned Apps feature to support app collaboration under a new project ID namespace. See our app developer documentation for more information.

2023-07-27

JavaScript and Python API (v0.1.361)

• Upgraded the client libraries to use the v1 Earth Engine API. No changes required except for the following case:

  • BACKWARD INCOMPATIBLE In the Python client, for the ee.data.getAsset() method, the title and description fields are only accessible from the asset properties in the v1 API. Modify your code to reference my_asset['properties']['title'] and my_asset['properties']['description'].

2023-07-19

Python API (v0.1.360)

• BACKWARD INCOMPATIBLE Added a Python version requirement (3.7.0) to the client libs.

Python and JavaScript API (v0.1.349)

• BACKWARD INCOMPATIBLE Removed support for dots (.) in workload tags, which will now throw an error.

2023-03-09

Web API

• Changed the default BIGTIFF parameter in the GeoTIFF image export options from IF_SAFER to YES, which always generates a BigTiff unless the BIGTIFF parameter is overridden in the formatOptions dictionary parameter.

2023-03-06

Web API

• Upgraded GDAL to ab9e803 and libgeotiff to a6fb3d3. Earth Engine uses GDAL to ingest assets and to export Cloud Optimized GeoTIFF (COG) files.

2023-02-15

Python API

• Added ee.data.getPixels(), ee.data.computePixels(), ee.data.listFeatures(), and ee.data.computeFeatures() to the Python client. The new methods will help with getting pixels from assets or ee.Image objects, and listing features from assets or ee.FeatureCollection objects.

2022-11-17

Web API

• Updated ee.Image.cumulativeCost to be able to handle multi-band cost images.

2022-11-02

Python API (v0.1.330)

• Improved Python ee.Authenticate() error messages to give more guidance, and fixed bugs.

2022-10-01

Web API

• For organizations with Google Workspace accounts, the organization administrator was given control to enable or disable Earth Engine by setting the Google Cloud on/off control. This control can be set for the entire organization or for specific workgroups. In August 2022, the organization administrators were notified of this change via a Mandatory Service Announcement (MSA), which included instructions for allowing access to Earth Engine. Who is my administrator?

2022-09-28

Python and JavaScript API (v0.1.326)

• Upgraded the client libraries to use the Earth Engine v1 API parameters instead of v1alpha only parameters, in preparation for a future migration to the v1 API.
• Refactored ee.data.getList() and ee.data.listImages() to call through to ee.data.listAssets() exclusively.

2022-08-17

Web API

• BACKWARD INCOMPATIBLE Fixed ee.Image.sampleRectangle() to use current band names instead of any original names.

2022-07-13

• Added support for Python 3.10 by removing the dependency on httplib2shim.
• Added a localhost auth mode and introduced a ee.oauth.Flow class for smoother integration with other client libraries.

2022-06-27

Google Cloud Platform

• Added Earth Engine as a Google Cloud product offering for commercial customers. See details here.

2022-06-27

Code Editor

• BACKWARD INCOMPATIBLE Changed Export logic in the Code Editor to no longer use the map bounds as a default region for the output. The Export behavior now matches that of the Python API, and calls which specify the projection parameters will remain unchanged. To use the viewport bounds as an export region, use Map.getBounds(true) as the region to get the geometry explicitly.

2022-06-22

Python API (v0.1.316)

• Added the workload tag API (ee.data.getWorkloadTag() and ee.data.setWorkloadTag()) to label computation and exports with a workload tag, which is viewable from the Google Cloud Console.

2022-01-06

Web API

• Added ee.String.equals().

2021-12-13

Code Editor

• Reinstated the allowHtml option for ui.Chart, while continuing to disallow external image display. Images in data: URLs and icons loaded from gstatic.com are allowed.
• Added imageUrl option to ui.Button and ui.Label. If provided, the image will be shown instead of the label text, which will then be used as a tooltip. As with ui.Chart, only images in data: URLs and icons loaded from gstatic.com are allowed.

2021-11-24

Web API

• Added ee.Geometry.coveringGrid, which returns a collection of 1x1 rectangles that cover a geometry in a specified projection. This is useful to generate e.g. all export tiles that cover a region of interest, and is far faster than building such a tiling with client-side for-loops.
• Added ee.Algorithm.TemporalSegmentation.StructuralChangeBreakpoints, modelled after R's wtrucchange.breakpoints. This looks for breakpoints in a time series of images, based on a linear+harmonic model of pixel values.

Code Editor

• Added an “Output URLs” list to the Task Manager, so that, when using Export.map.toCloudStorage(), you can easily copy-and-paste to add a tiled overlay to your Google Earth project, or for use with the Google Maps Platform JavaScript API.

2021-10-19

Code Editor

• BACKWARD INCOMPATIBLE Removed the allowHtml option from the set of allowed options in ui.Charts. This was done as a security precaution.

2021-09-15

Code Editor

• Launched a standalone Task Manager and a new interface in the Code Editor's "Tasks" tab. See our documentation for details.

2021-08-31

Web API

• Added ee.Reducer.circularMean(), ee.Reducer.circularStdDev(), and ee.Reducer.circularVariance().

2021-08-12

Python and JavaScript API (v0.1.278)

• Improved error reporting for the case where the arguments of a function passed to map() or iterate() are used in client-side operations that don't contribute to the function return value. Since the function is executed server-side, it may not have client-side effects. See the debugging guide for more details.

2021-07-15

Python API (v0.1.273)

• Added ee.Filter.bounds() alias for ee.Filter.geometry().

2021-06-24

• Added support for maxVertices parameter for table exports.

2021-04-22

JavaScript API (v0.1.262)

• Added a mechanism for overriding the default OAuth2 scopes requested in ee.data.authenticateViaOauth() and ee.data.authenticateViaPrivateKey(). This can be used for requesting the https://www.googleapis.com/auth/earthengine.readonly scope, rather than the https://www.googleapis.com/auth/earthengine scope requested by default.

2021-04-15

Web API

• Added ee.List.unzip().

2021-04-01

Code Editor

JavaScript API (v0.1.258)

• BACKWARD INCOMPATIBLE Patched ee.data.setAssetProperties() to prevent cases when setting system properties to null or zero causes unintentional property deletion.

2021-02-12

Web API

• Added ee.Number.signum(), ee.Image.signum(), and ee.Array.signum().
• Added a "RAW_REGRESSION" output mode to the smileRandomForest classifier.
• Fixed a bug that could cause non-uniform sampling of points from small (less than 300m) polygons.

2021-01-20

JavaScript API (v0.1.248)

• .evaluate() and other JavaScript functions that take callbacks will now report exceptions that occurred within callback functions to the console (or to the top level environment in Node.js). If your code has such an exception you can handle or suppress it with catch in the callback.

2021-01-19

Web API

• Added ee.Classifier.smileGradientTreeBoost() (see more) from the Smile library.

2020-12-03

Web API

2020-11-19

Web API

• Improved the reporting and handling of internal errors.
  • Added a (request: ...) ID string to "internal error" messages returned by the Earth Engine API. These IDs uniquely identify errors for debugging by the Earth Engine team. When reporting internal errors, please include this value.
  • Added a "Report error" link to errors in the Code Editor, making it easier to send feedback.

JavaScript API (v0.1.243)

• BACKWARD INCOMPATIBLE Removed functionality from the JavaScript client library which is no longer needed after the legacy API turndown.
  • Removed ee.data.getCloudApiEnabled and ee.data.setCloudApiEnabled from the JavaScript client library.

• Expanded ui.DateSlider to accept ee.Date object arguments. Improved ui.DateSlider sliding behavior, validation, and error reporting.
• Fixed ui.root.onResize() so that the callback is not fired after the script is reset or replaced.

2020-11-12

Python API

• BACKWARD INCOMPATIBLE Removed functionality from the Python client library which is no longer needed after the legacy API turndown.
  • Removed use_cloud_api parameter from ee.Initialize and data.initialize on the Python client library.
  • Removed the deprecated data.startProcessing method on the Python client library. Use exportImage, exportTable etc. instead.
  • Removed the use_cloud_api flag on the CLI tool.

2020-11-05

Web API

• The randomColumn and randomImage algorithms now take an optional distribution argument, which may be "uniform" or "normal".
• The loadGeoTIFF algorithm no longer rejects files with a Header ghost area, such as those written by recent versions of GDAL.

Code Editor

• Limit the minimum and maximum zoom level on Map or ui.Map objects by setting the minZoom or maxZoom parameters on setLocked().

2020-10-29

Code Editor

• Improved error reporting for syntax errors, by highlighting the error line in the editor and positioning the cursor at the location to fix. Syntax checks are performed before a script starts executing.

JavaScript API

• Fixes image export parsing of parameter skipEmptyTiles, which may have caused skipEmptyTiles to be ignored.

Python API

• Adds the task ID to the string representation of the task, compatible with the repr() function.

2020-10-15

Code Editor

• Fixed Map.centerObject when called with a single point. This now zooms to a small region around the point, instead of doing nothing.

JavaScript API

• Added file format validation and normalization to the ee.batch.Export methods on the JS client. Synonyms for file formats (e.g. "JPG" and "JPEG") are supported.

2020-09-25

Code Editor

• Added an indicator for the number of times a task was attempted. Earth Engine automatically attempts tasks a few times because some failures are sporadic. Likely causes for retries include exceeding memory limit and a temporary resource shortage.

JavaScript and Python API

• Added an ee.data.TaskStatus field for the number of times a task was attempted. This matches the value now shown in the Code Editor.

2020-09-11

Web API

• Added ee.Model.predictProperties() for making predictions over FeatureCollections.
• Eliminated one of the frequent causes of "Object too large" errors.
• Fixed bug that sometimes caused failures when using ReduceResolution close to projection singularities.

2020-08-21

Web API

• Added ee.Geometry.BBox(), which simplifies creation of rectangles of latitude and longitude.

Python API

• Added a --long_format option (and -l shortcut) to the earthengine task list CLI command, to show additional information about tasks. This change enables callers to see start/end times for individual tasks.

JavaScript and Python API

• Changed the object serialization format, so that x.serialize() returns an updated format (which is already used in server requests). ee.Deserializer supports both the new format and the old format. These changes apply to all JavaScript and Python APIs. If you have code which serializes and deserializes objects, we recommend that you either upgrade all parts of your system at once, or proceed in stages by updating the deserialization code first.

2020-07-07

Web API

• Added ee.Algorithms.ObjectType(), which returns the type of any computed object.
• Fixed bug that could cause export of an all-zero image to fail.

• Dismissed popup dialogs when the mouse scrolls elsewhere on the page.

2020-01-30

Python API

• Updated the HTTP transport layer for the Earth Engine Python client library from httplib2 to urllib3, which will make it more flexible (e.g., it's now possible to make multiple simultaneous requests) and improve performance. This improvement might not be realized if the earthengine-api package is installed via the conda-forge channel.

Web API

• Fixed the explain() method of ee.Classifier.SmileRandomForest() to return importance as a dictionary.

2020-01-23
