geetools.ImageAccessor.distanceToMask

geetools.ImageAccessor.distanceToMask(mask, kernel='euclidean', radius=1000, band_name='distance_to_mask')

Compute the distance from each pixel to the nearest non-masked pixel.

Parameters:

• mask (ee.Image) – The mask to compute the distance to.

• kernel (str) – The kernel type to use for the distance computation default to “euclidean”.

• radius (int) – The radius of the kernel.

• band_name (geetools.types.ee_str) – The name of the band to store the distance values.

Returns:

The original images with the distance band added.

Return type:

ee.Image

Examples

import ee, geetools

ee.Initialize()

image = ee.Image('COPERNICUS/S2_SR/20190828T151811_20190828T151809_T18GYT')
centerBuffer = image.geometry().centroid().buffer(100)
BufferMask = ee.Image.constant(1).clip(centerBuffer)
mask = ee.Image.constant(0).where(BufferMask, 1).clip(image.geometry())
image = image.distanceToMask(mask)
