ee.Array.neq

  • Array.neq() is an Earth Engine function that performs an element-wise comparison of two arrays, returning 1 if the corresponding elements are not equal and 0 if they are equal.

  • The function takes two arguments: left (the first array) and right (the second array), and it returns a new array with the comparison results.

  • It's essential to be aware of data types when using neq(), as comparisons between different data types (e.g., float and double) might yield unexpected results due to floating-point representation.

  • The function returns an empty array ([]) if either input array is empty.

 On an element-wise basis, returns 1 if and only if the first value is not equal to the second.

UsageReturns
Array.neq(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.neq(empty));  // []

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

print(ee.Array([1.1]).neq(ee.Array([1.1])));  // 0
print(ee.Array([1.1]).float().neq(ee.Array([1.1])));  // 1
print(ee.Array([1.1]).double().neq(ee.Array([1.1])));  // 0

print(ee.Array([1]).int8().neq(ee.Array([1])));  // 0
print(ee.Array([1]).int8().neq(ee.Array([1]).int32()));  // 0
