in my case study I use these api together: matrix and directions
before making an api matrix request for N points I check if each points are reachable to the graph, I check this condition with the api directions and I rely on the
If one of the N points has no routing solution with a certain
maximum_snapping_radius then I exclude it from the next matrix request.
I would like to know if the
matrix.maximum_search_radius parameter is calculated in a similar way to
directions.maximum_snapping_radius and if they can be set to the same value.
I thought that for right behavior
directions.maximum_snapping_radius it should be a little bit bigger to say
this is because sometimes it happens that two points are “reachable” with directions but they are not reachable by matrix
