Commonly used constant image GEE codes:
In GEE, you can generate a constant image using:
- Use ee.Number to generate a numeric constant image:
var constantImage = ee.Image.constant(100);
This will generate an image with all pixel values at 100.
- Use ee.Image.constant to generate an image with constant values:
var constantImage = ee.Image.constant({
bands: ['constant_band'],
value: 100
});
This will generate an image with a band called 'constant_band' where all pixels have a value of 100.
- Generate a constant image using spatial resolution and projection information:
var constantImage = ee.Image.constant(0)
.toInt()
.reproject({
crs: 'EPSG:4326',
scale: 30
});
This will generate an integer image with all pixel values 0, using the WGS84 projection and a spatial resolution of 30 meters.
