16-to-8 Bit Conversion

Converts 16 bit imagery from Sentinel-2 into 8 bit imagery.


Description

A processing block that enables using partner processing blocks that require 8 bit imagery with 16 bit imagery from Sentinel-2 L2A.

See this block on the marketplace.

How it works

This block has no configurable JSON parameters.

The block takes 16 bit GeoTIFF images as input and applies a conversion factor to output 8 bit GeoTIFF images. The conversion uses the formula below:

result=val_12bit2812121result = val{\_}12bit \frac{2^8 - 1}{2^{12} - 1}

Example

A workflow with the following blocks:
