Hello everyone, I hope you’re all doing well.
I’m currently working on sending a request that involves multiple polygons. However, I’m encountering an issue where there’s a red area appearing between the polygons, when visualizing the NDVI index
Here’s my script :
//VERSION=3
function setup() {
return {
input: "B04", "B08", "SCL", "dataMask"],
output:
{ id: "default", bands: 4 },
{ id: "index", bands: 1, sampleType: "FLOAT32" },
{ id: "eobrowserStats", bands: 2, sampleType: "FLOAT32" },
{ id: "dataMask", bands: 1 },
],
};
}
function evaluatePixel(samples) {
let val = index(samples.B08, samples.B04);
let imgVals = null;
const indexVal = samples.dataMask === 1 ? val : NaN;
if (val < -0.5) imgVals = i0.05, 0.05, 0.05, samples.dataMask];
else if (val < -0.2) imgVals = i0.75, 0.75, 0.75, samples.dataMask];
else if (val < -0.1) imgVals = i0.86, 0.86, 0.86, samples.dataMask];
else if (val < 0) imgVals = i0.92, 0.92, 0.92, samples.dataMask];
else if (val < 0.025) imgVals = i1, 0.98, 0.8, samples.dataMask];
else if (val < 0.05) imgVals = i0.93, 0.91, 0.71, samples.dataMask];
else if (val < 0.075) imgVals = i0.87, 0.85, 0.61, samples.dataMask];

else if (val < 0.5) imgVals = i0.19, 0.43, 0.1972, samples.dataMask];
else if (val < 0.55) imgVals = i0.13, 0.38, 0.07, samples.dataMask];
else if (val < 0.6) imgVals = i0.06, 0.33, 0.04, samples.dataMask];
else imgVals = i0, 0.27, 0, samples.dataMask];
return {
default: imgVals,
index: indexVal],
eobrowserStats: sval, isCloud(samples.SCL) ? 1 : 0],
dataMask: dsamples.dataMask],
};
}
function isCloud(scl) {
if (scl == 3) {
// SC_CLOUD_SHADOW
return false;
} else if (scl == 9) {
// SC_CLOUD_HIGH_PROBA
return true;
} else if (scl ==

return false;
