How to integrate two horizontal factors in path distance function?

Discussion created by paulvanpelt on May 9, 2013
Dear all,

Perhaps this is an easy query, but I am trying to perform a path distance calculation for the movement of a ship on the ocean (starting from a fixed port). I am dealing with two horizontal friction elements instead of one, being 1) wind direction and speed and 2) current direction and speed. The horizontal factor search settings for both friction elements are determined in two separate tables. Is there any way to perform a path distance calculation using both horizontal factors?

Any help would be greatly appreciated.

All the very best,
