Dear Community, I am using SH evalscript to compute ndvi and render the layer on my application. The issue is that when users clic on a pixel within the ndvi image that SH returns, they see the colour array values and not the actual ndvi value as the pixel value. Is there away around this?
example code:
//VERSION=3
function setup() {
return {
input: [{
bands:["B04", "B08"],
}],
output: {
id: "default",
bands: 3,
}
}
}
function evaluatePixel(sample) {
let ndvi = (sample.B08 - sample.B04) / (sample.B08 + sample.B04)
if (ndvi<-0.5) return [0.05,0.05,0.05]
else if (ndvi<-0.2) return [0.75,0.75,0.75]
else if (ndvi<-0.1) return [0.86,0.86,0.86]
else if (ndvi<0) return [0.92,0.92,0.92]
else if (ndvi<0.025) return [1,0.98,0.8]
else if (ndvi<0.05) return [0.93,0.91,0.71]
else if (ndvi<0.075) return [0.87,0.85,0.61]
else if (ndvi<0.1) return [0.8,0.78,0.51]
else if (ndvi<0.125) return [0.74,0.72,0.42]
else if (ndvi<0.15) return [0.69,0.76,0.38]
else if (ndvi<0.175) return [0.64,0.8,0.35]
else if (ndvi<0.2) return [0.57,0.75,0.32]
else if (ndvi<0.25) return [0.5,0.7,0.28]
else if (ndvi<0.3) return [0.44,0.64,0.25]
else if (ndvi<0.35) return [0.38,0.59,0.21]
else if (ndvi<0.4) return [0.31,0.54,0.18]
else if (ndvi<0.45) return [0.25,0.49,0.14]
else if (ndvi<0.5) return [0.19,0.43,0.11]
else if (ndvi<0.55) return [0.13,0.38,0.07]
else if (ndvi<0.6) return [0.06,0.33,0.04]
else if (ndvi<0.65) return [0.44,0.64,0.25]
else if (ndvi<0.7) return [0.38,0.59,0.21]
else if (ndvi<0.75) return [0.31,0.54,0.18]
else if (ndvi<0.8) return [0.25,0.49,0.14]
else if (ndvi<0.85) return [0.19,0.43,0.11]
else if (ndvi<0.9) return [0.13,0.38,0.07]
else if (ndvi<0.95) return [0.06,0.33,0.04]
else return [0,0.27,0]
}
and when one clicks on a pixel whose ndvi value is supposed to be between 90 and 94 for example in the above scrept, the value 0.06 would pop up (and this is not true).
