ee.Array.eq

  • Array.eq() compares two arrays element-by-element and returns 1 if the elements are equal, otherwise 0.

  • The comparison considers data type, so arrays with different types may not be considered equal even if their numerical values are the same.

  • It returns an empty array [] if either of the input arrays is empty.

  • This function can be used with both JavaScript and Python APIs in Google Earth Engine.

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

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

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

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

print(ee.Array([1]).int8().eq(ee.Array([1])));  // 1
print(ee.Array([1]).int8().eq(ee.Array([1]).int32()));  // 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.eq(empty))  # []

display(ee.Array([0]).eq(ee.Array([1])))  # 0
display(ee.Array([0]).eq(ee.Array([0])))  # 1

display(ee.Array([1.1]).eq(ee.Array([1.1])))  # 1
display(ee.Array([1.1]).float().eq(ee.Array([1.1])))  # 0
display(ee.Array([1.1]).double().eq(ee.Array([1.1])))  # 1

display(ee.Array([1]).int8().eq(ee.Array([1])))  # 1
display(ee.Array([1]).int8().eq(ee.Array([1]).int32()))  # 1
