WebJun 19, 2024 · Area calculation for images is done using the ee.Image.pixelArea () function. This function creates an image where each pixel’s value is the area of the pixel. If the image pixels contains values 0 or 1 – we can multiply this pixel area image with our image and calculate the total area using reduceRegion () function. 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 ...

WebReducer. median ()) # Convert the image collection to a feature collection with the reducer function ## this step just applies the function we created above ... Google Earth Engine's workflow in processed via communication between your computer/Python API and Google's servers for computation. In order to plot charts without the ability to use ... WebTo reduce an ImageCollection , use imageCollection.reduce (). This reduces the collection of images to an individual image as illustrated in Figure 1. Specifically, the output is computed pixel-wise, such that each pixel in the output is composed of the median value of all the images in the collection at that location. how do you describe a crystalline structure

When considering a reducer for an image collection, note that the output is an image, so reducers with non-numeric outputs, for example histogram or toList reducers, won't work with an image collection.
