Earth Engine has introduced
noncommercial quota tiers to safeguard shared compute resources and ensure reliable performance for everyone. Noncommercial projects use the Community Tier by default, though you can change a project's tier at any time.

Transforms the geometry to a specific projection.
| Usage | Returns | MultiPolygon.transform(proj, maxError, geodesic) | Geometry |
| Argument | Type | Details | this: geometry | Geometry | The geometry to reproject. |
proj | Projection, optional | The target projection. Defaults to EPSG:4326. If this has a geographic CRS, the edges of the geometry will be interpreted as geodesics. Otherwise they will be interpreted as straight lines in the projection. This default can be overridden by the geodesic parameter. |
maxError | ErrorMargin, default: null | The maximum projection error. |
geodesic | Boolean, default: null | Whether to interpret edges as geodesics. If true, edges are interpreted as the shortest path on the surface of the earth. If false, edges are interpreted as straight lines in the projection. Defaults to true if the target projection is geographic, and false otherwise. |

[null,null,["Last updated 2026-07-01 UTC."],[],["The `transform` function reprojects a geometry to a specified projection. It accepts the geometry itself, the target projection (`proj`), and an optional `maxError` parameter to control accuracy. The function defaults to EPSG:4326 if no projection is provided. The target projection determines if the edges are interpreted as geodesics or straight lines, and the result is a new geometry with the applied projection.\n"]]
