verify noncommercial eligibility to maintain Earth Engine access.
ee.Number.unitScale
Stay organized with collections
Save and categorize content based on your preferences.
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.
import ee
import geemap.core as geemap
Colab (Python)
print('-10 scaled between [0, 100]:',
ee.Number(-10).unitScale(0, 100).getInfo()) # -0.1
print('10 scaled between [0, 100]:',
ee.Number(10).unitScale(0, 100).getInfo()) # 0.1
