i’m trying to make this process : mla(): Execute supervised classification in satellite images using various algorithms.
//VERSION=3
function setup() {
return {
input: ["B8", "B4"], // NIR and RED bands
output: { bands: 3 }
};
}
function evaluatePixel(sample) {
let ndvi = index(sample.B8, sample.B4); // Calculate NDVI
if (ndvi > 0.3) {
// Vegetation threshold, adjust as necessary
return [0, 1, 0]; // Green for high NDVI values
} else {
return [1, 1, 1]; // White for low NDVI values
}
}
function index(NIR, RED) {
return (NIR - RED) / (NIR + RED);
}
