EO Browser - Sentinel 2 indices geoTIFF Raster bands

4

Hi @meteoclima,

Sorry, there was a typo in @dorothyrono’s code: it is missing the parameter that sets the output number of bands, which in this case should be 1.

If you try the following Evalscript, it should work (see example):

//VERSION=3
function setup() {
  return {
    input: ["B08", "B04"],
    output: { bands: 1 }
  };
}

function evaluatePixel(sample) {
  var ndvi = (sample.B08 - sample.B04) / (sample.B08 + sample.B04);  
  return [ndvi];
}

Note: this script in itself is designed for display purposes (scaled to the range 0-255). However, when you select Image format: TIFF (32-bit float) in the download section of EO Browser (under Analytical) the system will retrieve the raw values in Float for you.
