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

Page Summary
A pixel grid on the Earth's surface is defined by a map projection.
Standard projections usecrsCode, while non-standard ones usecrsWkt.
An affine post-projection transformation is indicated by theaffineTransformfield.
Defines a pixel grid on the surface of the Earth, via a map projection. If the projection has a standard code, thencrsCodewill be set (non-empty). If the projection is non-standard, thencrsWktwill be set. If the post-projection transformation is affine, thenaffineTransformwill be set.

Union fieldcrs. The coordinate reference system of the pixel grid, specified as a standard code where possible, and in WKT format otherwise.crscan be only one of the following:
crsCode
string
A standard coordinate reference system code (e.g. "EPSG:4326").
crsWkt
string
A coordinate reference system in WKT format ("Well-Known Text").

Key data includes `dimensions` and an optional `affineTransform` for post-projection affine transformations. The coordinate reference system (`crs`) is defined via either a standard `crsCode` (e.g., \"EPSG:4326\") or, if non-standard, a `crsWkt` (Well-Known Text) string.
