Earth Engine is introducing
noncommercial quota tiers to safeguard shared compute resources and ensure reliable performance for everyone. All noncommercial projects will need to select a quota tier by
April 27, 2026 or will use the Community Tier by default. Tier quotas will take effect for all projects (regardless of tier selection date) on
April 27, 2026.

Stay organized with collections
Save and categorize content based on your preferences.
Applies transformations and returns the thumbId.
Returns the thumb ID and optional token, or null if a callback is specified.
| Usage | Returns | Image.getThumbId(params, callback) | ThumbnailId |
| Argument | Type | Details | this: image | Image | The Image instance. |
params | Object | Parameters identical to ee.data.getMapId, plus, optionally:
dimensions (a number or pair of numbers in format WIDTHxHEIGHT) Maximum dimensions of the thumbnail to render, in pixels. If only one number is passed, it is used as the maximum, and the other dimension is computed by proportional scaling. |
region Geospatial region of the image to render, it may be an ee.Geometry, GeoJSON, or an array of lat/lon points (E,S,W,N). If not set the default is the bounds image. |
|
callback | Function, optional | An optional callback. If not supplied, the call is made synchronously. |

[null,null,["Last updated 2024-02-20 UTC."],[],["The `Image.getThumbId` function retrieves a thumbnail ID. It accepts `params`, an object that defines thumbnail properties like `dimensions` (specifying maximum pixel width and height) and `region` (a geospatial area to render). The function can optionally take a `callback` for asynchronous operation. It returns a `ThumbnailId`, and if a callback is provided, it returns null. If no callback is passed the function executes synchronously. The function operates on an `Image` instance.\n"]]
