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 | A single-band 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). |
