Apply a reducer to all the pixels in a specific region.
Either the reducer must have the same number of inputs as the input image has bands, or it must have a single input and will be repeated for each band.
Returns a dictionary of the reducer's outputs.
The image to reduce.
The reducer to apply.
|Geometry, default: null|
The region over which to reduce data. Defaults to the footprint of the image's first band.
|Float, default: null|
A nominal scale in meters of the projection to work in.
|Projection, default: null|
The projection to work in. If unspecified, the projection of the image's first band is used. If specified in addition to scale, rescaled to the specified scale.
|List, default: null|
The list of CRS transform values. This is a row-major ordering of the 3x2 transform matrix. This option is mutually exclusive with 'scale', and replaces any transform already set on the projection.
|Boolean, default: false|
If the polygon would contain too many pixels at the given scale, compute and use a larger scale which would allow the operation to succeed.
|Long, default: 10000000|
The maximum number of pixels to reduce.
|Float, default: 1|
A scaling factor used to reduce aggregation tile size; using a larger tileScale (e.g. 2 or 4) may enable computations that run out of memory with the default.
