Earth engine reducers
WebReducers take an input dataset and produce a single output. When a single input reducer is applied to a multi-band image, Earth Engine automatically replicates the reducer and applies it separately to each band. As a result, the output image has the same number of bands as the input image; each band in the output is the reduction of pixels from ... Reducers take an input dataset and produce a single output. When a single input reducer is applied to a multi-band image, Earth Engine … See more If your intent is to apply multiple reducers to the same inputs, it's good practice to combine() the reducers for efficiency. Specifically, calling combine() on a reducer with … See more By default, reductions over pixel values are weighted by their mask, though this behavior can be changed (see the Weighting section). Pixels with mask equal to 0 will not be used in the reduction. See more
