ee.Array.lte

  • Array.lte() is an Earth Engine function that performs an element-wise comparison of two arrays, returning 1 if the element in the first array is less than or equal to the corresponding element in the second array, and 0 otherwise.

  • The function takes two arguments: the left-hand array (left) and the right-hand array (right), and returns a new array with the results of the comparison.

  • If either input array is empty, an empty array is returned.

  • This function can be used in both JavaScript and Python environments within the Google Earth Engine platform.

 On an element-wise basis, returns 1 if and only if the first value is less than or equal to the second.

UsageReturns
Array.lte(right)Array
ArgumentTypeDetails
this: leftArrayThe left-hand value.
rightArrayThe right-hand value.

Examples

Code Editor (JavaScript)

var empty = ee.Array([], ee.PixelType.int8());
print(empty.lte(empty));  // []

print(ee.Array([0]).lte([0]));  // [1]
print(ee.Array([1]).lte([2]));  // [1]
print(ee.Array([2]).lte([1]));  // [0]

print(ee.Array([-1, 0, 1]).lte([-2, 1, 1]));  // [0,1,1]

Python setup

See the Python Environment page for information on the Python API and using geemap for interactive development.

import ee
import geemap.core as geemap

Colab (Python)

empty = ee.Array([], ee.PixelType.int8())
display(empty.lte(empty))  # []

display(ee.Array([0]).lte([0]))  # [1]
display(ee.Array([1]).lte([2]))  # [1]
display(ee.Array([2]).lte([1]))  # [0]

display(ee.Array([-1, 0, 1]).lte([-2, 1, 1]))  # [0, 1, 1]
