I am designing GEE App and want to download NDVI in GeoTIFF format using ee.Image.getDownloadURL for client side using following code:

var urlLabel = ui.Label('Download', {shown: true}); 
var btn_export = ui.Button({label:'Donwload Image (this an take a few minutes)', 
onClick: function(){ 
var downloadArgs = {
    name: 'Rice',
    crs: 'EPSG:4326',
    scale: 20,
    region: AOI
  var url = range.getDownloadURL(downloadArgs);
  urlLabel.style().set({shown: true});

but I am unable to download NDVI image.

You should try something like

Export.image.toDrive({image: dNBR, scale: 30, description: id, fileNamePrefix: 'dNBR', region: area, maxPixels: 1e10});

UseCase UN-Spider Code UN-Spider

  • Thankyou for your response, but I think this command doesn't work for Earth_Engine_App.
