Announcement: All noncommercial projects registered to use Earth Engine before
April 15, 2025 must
verify noncommercial eligibility to maintain Earth Engine access.
Objects and Methods Overview
Stay organized with collections
Save and categorize content based on your preferences.
The Earth Engine API is composed of objects and methods. Objects represent data
types such as raster images, vector features, numbers, and strings.
Each of these objects belongs to a specific class, and each class has a
strict set of functions available to it.
Objects and methods are combined in workflow scripts and sent to Earth Engine
servers for processing. Learn about common object classes and their methods by
clicking on the following cards to see example procedures.
The full list of Earth Engine classes and their methods can be found in the
Client Libraries section of the API Reference Guide
(e.g. ee.Image.add). The same
reference information is also available under the JavaScript Code Editor
Docs tab.
Common Earth Engine object classes
Image
The fundamental raster data type in Earth Engine.
Geometry
The fundamental vector data type in Earth Engine.
Feature
A geometry with attributes.
Reducer
An object used to compute statistics or perform aggregations.
Join
Combine datasets (Image or Feature collections) based on time, location, or an attribute property.
Array
An object for multi-dimensional analyses.
Chart
An object for charting properties and spatiotemporal reductions.
