ee.Algorithms.If
Stay organized with collections
Save and categorize content based on your preferences.
Selects one of its inputs based on a condition, similar to an if-then-else construct.
Usage | Returns | ee.Algorithms.If(condition, trueCase, falseCase) | Object |
Argument | Type | Details | condition | Object, default: null | The condition that determines which result is returned. If this is not a boolean, it is interpreted as a boolean by the following rules:
- Numbers that are equal to 0 or a NaN are false.
- Empty strings, lists and dictionaries are false.
- Null is false.
- Everything else is true.
|
trueCase | Object, default: null | The result to return if the condition is true. |
falseCase | Object, default: null | The result to return if the condition is false. |
Examples
Code Editor (JavaScript)
print(ee.Algorithms.If(false, '*true*', '*false*')); // The string "*false*"
print(ee.Algorithms.If(true, '*true*', '*false*')); // The string "*true*"
// Consider using remap rather than If for tasks like numbers for classes.
print(ee.Algorithms.If(ee.String('Tree').compareTo('Tree'), 0, 1));
print(ee.Algorithms.If(ee.String('NotTree').compareTo('Tree'), 0, 1));
Python setup

# The string "*false*"
print(ee.Algorithms.If(False, '*true*', '*false*').getInfo())
# The string "*true*"
print(ee.Algorithms.If(True, '*true*', '*false*').getInfo())
# Consider using remap rather than If for tasks like numbers for classes.
print(ee.Algorithms.If(ee.String('Tree').compareTo('Tree'), 0, 1).getInfo())
print(ee.Algorithms.If(ee.String('NotTree').compareTo('Tree'), 0, 1).getInfo())
