An image representing the cost to traverse each pixel. Masked pixels can't be traversed. When comparing pixel traversal costs, we use band-wise dictionary ordering. Ancillary cost bands are only considered when paths over primary bands are equal cost.
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).
