ee.Number.unitScale

AI-generated Key Takeaways

• Scales an input number from a specified range [min, max] to [0, 1].

• Values outside the initial [min, max] range are not restricted or changed by this scaling.

• If the minimum and maximum values of the input range are the same, the function returns 0.

Scales the input so that the range of input values [min, max] becomes [0, 1]. Values outside the range are NOT clamped. If min == max, 0 is returned.

Usage	Returns
Number.unitScale(min, max)	Number

Argument	Type	Details
this: number	Number
min	Float
max	Float

Examples

Code Editor (JavaScript)

print('-10 scaled between [0, 100]', ee.Number(-10).unitScale(0, 100));  // -0.1
print('10 scaled between [0, 100]', ee.Number(10).unitScale(0, 100));  // 0.1

Python setup

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

Colab (Python)

display('-10 scaled between [0, 100]:',
        ee.Number(-10).unitScale(0, 100))  # -0.1
display('10 scaled between [0, 100]:',
        ee.Number(10).unitScale(0, 100))  # 0.1
