Accumulated wind cost surface
least_cost_surface.RdCalculate the accumulated wind cost-distance (e.g. travel times) or flow rate (the inverse of cost-distance) from one or more sites to every grid cell across the domain, using the least cost path algorithm. This function is a wrapper around accCost.
Arguments
- graph
A wind_graph.
- sites
A two-column matrix of point coordinates.
- rate
Whether to return values as "rates" instead of the default "cost distances". Rates are the inverse of cost distances, representing flow rather than travel time.
