this:
cost
|
Image | 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). |
