Downsampling

The Downsampling operator decreases raster resolution by sampling values of an input raster. If queried with a resolution that is finer than the input resolution, downsampling is not applicable and an error is returned. ## Inputs The Downsampling operator expects exactly one raster input. ## Resolution The target resolution can be specified either as an explicit Resolution (in pixel units) or as a Fraction that scales the input resolution. rust,ignore // Scale the input resolution by a factor of 2 in both x and y directions DownsamplingResolution::Fraction(Fraction { x: 2.0, y: 2.0 }) rust,ignore // Use an explicit resolution of 200×200 pixel units DownsamplingResolution::Resolution(SpatialResolution { x: 200.0, y: 200.0 })

Example

import type { Downsampling } from '@geoengine/api-client'

// TODO: Update the object below with actual values
const example = {
  "type": null,
  "params": null,
  "sources": null,
} satisfies Downsampling

console.log(example)

// Convert the instance to a JSON string
const exampleJSON: string = JSON.stringify(example)
console.log(exampleJSON)

// Parse the JSON string back to an object
const exampleParsed = JSON.parse(exampleJSON) as Downsampling
console.log(exampleParsed)
