ee.Image.pixelLonLat

  • Generates an image containing pixel-wise longitude and latitude values in degrees, accessible via two bands named 'longitude' and 'latitude'.

  • The function ee.Image.pixelLonLat() is used to create this image, requiring no arguments.

  • This image can be utilized for various geospatial analyses, such as calculating UTM zones as shown in the examples.

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