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
BBox.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.

It accepts the geometry to be reprojected, the desired projection (defaulting to EPSG:4326), and an optional maximum projection error. If the target projection is geographic, geometry edges are treated as geodesics; otherwise, they're considered straight lines. The function returns the transformed geometry after the projection operation is complete.\n"]]
