Thermal image/NDVI/Moisture index geotiff has 3 bands

Hi there,

I’ve downloaded thermal images from landsat8/9, NDVI, and moisture index from sentinel 2 within an area of interest using The Analytical tab in the image downloader.
I downloaded 32bits geotiff georeferenced images to use in GIS.
The downloaded image for all cases was a georeferenced 3-band geotif.
None of the bands show the temperature values that appear in the browser.
I was expecting a raster with one band and a range of values identical to what is shown on the browser for these products.
Is it possible to download such information using the browser? If so, how?

Thanks in advance

Hi Maria,

Thanks for the question, in fact EO Browser is primarily designed to be used to visualise data, that is why you will have returned a three band image whose values correspond to the visualisation of the index/thermal band.

However, you can output the analytical data if required. To do this, you will need to select the custom script option and for Band 10 of Landsat 8/9 you could insert the following:

//VERSION=3
function setup() {
  return {
    input: ["B10", "dataMask"],
    output: { bands: 1 }
  };
}

function evaluatePixel(sample) {
  return [sample.B10];
}

You can then download the analytical data that you are looking for :slight_smile:
