Hi everyone, I’m trying to acoomplish the following:
I would like to get a tiff, with only one band with two possible values 0 or 1, being 1 when SCL layer has the values 8,9 and 10 and being 0 when SCL band has other values
in order to accomplish that I did the following, but it doesn,t seem to work.

request:
{
“input”: {
“bounds”: {
“properties”: {
“crs”: “http://www.opengis.net/def/crs/OGC/1.3/CRS84”
},

}

EVAL SCRIPT:
//VERSION=3
function setup() {
return{
input: [ “SCL”],
output: {bands: 1}
}
}

function evaluatePixel(sample) {
if ([8, 9, 10].includes(sample.SCL) ){
return [1]
} else{
return [0]
}
}

I have to clarify that the selected area and date has been chosen because they are partially cloudy, so I was specting to get some values in 1 following the shape of the clouds and the rest in 0.

Can anyone give me a hand on this…sugestions…
thanks in advance.

Hi hbalussi,

your request seems to work nicely for me. I get:

Cordoba.tiff (3.1 KB)

To me it seems that the shape of the cloud roughly corresponds to what I can see in the true color ima ge:Sentinel Hub EO Browser

Is the result not in line with what you expect?
