ee.Image.pixelLonLat

AI-generated Key Takeaways

• The ee.Image.pixelLonLat() method creates an image with 'longitude' and 'latitude' bands representing the coordinates at each pixel.

• This method does not require any arguments.

• Examples in both JavaScript and Python demonstrate how to use this method to calculate and visualize UTM zones.

Creates an image with two bands named 'longitude' and 'latitude', containing the longitude and latitude at each pixel, in degrees.

Usage	Returns
ee.Image.pixelLonLat()	Image

No arguments.

Examples

Code Editor (JavaScript)

// https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system
var longitude = ee.Image.pixelLonLat().select('longitude');
var utmZones = longitude.add(180).divide(6).int();
Map.addLayer(utmZones, {min:0, max: 60}, 'UTM zones');
