ee.Image.cumulativeCost

Computes a cumulative cost map based on an image containing costs to traverse each pixel and an image containing source locations.

Usage	Returns
Image.cumulativeCost(source, maxDistance, geodeticDistance)	Image

Argument	Type	Details
this: cost	Image	An image representing the cost to traverse each pixel. Masked pixels can't be traversed.
source	Image	A single-band image representing the sources. A pixel value different from 0 defines a source pixel.
maxDistance	Float	Maximum distance for computation, in meters.
geodeticDistance	Boolean, default: true	If true, geodetic distance along the curved surface is used, assuming a spherical Earth of radius 6378137.0. If false, euclidean distance in the 2D plane of the map projection is used (faster, but less accurate).
