What $($specifically$)$ were the constraints $($in terms of cost distance factors$)$ placed on this shortest path calculation?

The calculation incorporated elevation changes to reflect varying traversal difficulty across different elevations.

There were no constraints$-$this assumes that the surface being traversed is a flat, featureless, plain.

The calculation considered varying costs based on different land use types and terrain features.

The calculation accounted for changes in travel speed due to weather conditions affecting traversal costs.
