Examples
Code Editor (JavaScript)
print('Lanczos approx. of -1', ee.Number(-1).lanczos()); // Infinity
print('Lanczos approx. of -0.9', ee.Number(-0.9).lanczos()); // 524.955196990
print('Lanczos approx. of 0', ee.Number(0).lanczos()); // 32.946318679
print('Lanczos approx. of 10', ee.Number(10).lanczos()); // 2.281783181
print('Lanczos approx. of 1e10', ee.Number(1e10).lanczos()); // 1.000000001
Python setup
See the
Python Environment page for information on the Python API and using
geemap for interactive development.

import geemap.core as geemap
Colab (Python)
print('Lanczos approx. of -1:', ee.Number(-1).lanczos().getInfo()) # Infinity
print('Lanczos approx. of -0.9:',
ee.Number(-0.9).lanczos().getInfo()) # 524.955196990
print('Lanczos approx. of 0:', ee.Number(0).lanczos().getInfo()) # 32.946318679
print('Lanczos approx. of 10:',

print('Lanczos approx. of 1e10:',
ee.Number(1e10).lanczos().getInfo()) # 1.000000001
