| Argument | Type | Details | this: left | Array | The left-hand value. |
right | Array | The right-hand value. |
Examples
Code Editor (JavaScript)
var empty = ee.Array([], ee.PixelType.int8());
print(empty.or(empty)); // []
print(ee.Array([0, 0, 1, 1]).or(ee.Array([0, 1, 0, 1]))); // [0,1,1,1]
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.Or(empty)) # []
# [0, 1, 1, 1]
display(ee.Array([0, 0, 1, 1]).Or(ee.Array([0, 1, 0, 1])))
