I am trying to download a specific Landsat scene (since the USGS EROS site is down from the government shutdown) using the imageToCOGeoTiff task to save to my Google Drive. I am using the USGS Landsat 8 Collection 1 Tier 1 TOA Reflectance data.
I get the error message:
Error: Exported bands must have compatible data types; found inconsistent types: Float32 and UInt16.
I understand that all bands are "float" except for the BQA band which is "int16". I only need bands 1 – 11, not the BQA. Is there any way to select the bands I want (or to remove the BQA band)?
This is what I have so far (I am very new to GEE and most of this code was derived from elsewhere):
var lsat = ee.Image(landsat.filterDate('2016-06-27','2016-06-29').filterBounds(point).first());
// Print the image to the console
print(lsat);
// Define vis parameter
var trueColor = {
bands: ['B4','B3','B2'],
min: 6000,
max: 13000,
};
// Add the image to the map
Map.addLayer(lsat,trueColor,'True Color Image');
// Export a cloud-optimized GeoTIFF.
Export.image.toDrive({
image: lsat,
description: 'imageToCOGeoTiffExample',
scale: 30,
fileFormat: 'GeoTIFF',
maxPixels: 11629187501,
formatOptions: {
cloudOptimized: true
}
});

You could use the following to select the first 11 bands:
You could also cast the bands to the same data type:
