I tried to increase the time window to up to 8 months and set least cloud cover to 15 percent, but I am getting images that are too bright or completely dark, although the area is just 74.5 km2 which is large enough to not be completely dominated by clouds I assume. Is there a work around to get decent images for time series analysis of this specific area.
Hi Aswin Manohar!, in your Evalscript you are returning many bands, why don’t you try this example for true color:
//VERSION=3
function setup(){
return{
input: ["B02", "B03", "B04", "dataMask"],
output: {bands: 4}
}
}
function evaluatePixel(sample){
// Set gain for visualisation
let gain = 2.5;
// Return RGB
return [sample.B04 * gain, sample.B03 * gain, sample.B02 * gain, sample.dataMask];
}
Thanks for the answer @adrian.dipaolo. we have an in-house sentinel-2 processing pipeline for few analysis and true colour image is a part of it. I’d prefer get all the bands and do our own processing.
Then when you open the TIFF in Qgis, you should double click the layer in the Layers Panel and set in the properties the bands to B4 (Red), B3 (Green) and B2 (Blue) as you can see here:
