ee.Geometry.Polygon.coveringGrid

Returns a collection of features that cover this geometry, where each feature is a rectangle in the grid defined by the given projection.

Usage	Returns
Polygon.coveringGrid(proj, scale)	FeatureCollection

Argument	Type	Details
this: geometry	Geometry	The result is the grid cells that intersect with this region.
proj	Projection	The projection in which to construct the grid. A feature is generated for each grid cell that intersects 'geometry', where cell corners are at integer-valued positions in the projection. If the projection is scaled in meters, the points will be on a grid of that size at the point of true scale.
scale	Float, default: null	Overrides the scale of the projection, if provided. May be required if the projection isn't already scaled.
