Hi Daniel
I'm running a release version of OSRM which I downloaded and compiled
from the instructions given.
The main thing I am after is the driving time and distance initially,
not interested in alternate route or anything else. In OSRM v4 using the
simpleclient.cpp as a base for my code, I used the following parameters:
// Set up the parameters required.
RouteParameters route_parameters;
route_parameters.zoom_level = 18; // no
generalization
route_parameters.print_instructions = false; // turn by
turn instructions
route_parameters.alternate_route = false; // get an
alternate route, too
route_parameters.geometry = false; //
retrieve geometry of route
route_parameters.compression = false; //
polyline encoding
route_parameters.check_sum = -1; // see wiki
route_parameters.service = "viaroute"; // that's
routing
route_parameters.output_format = "json";
route_parameters.jsonp_parameter = ""; // set for jsonp
wrapping
I did try and search in the source code for the equivalent, but couldn't
find the right source file. Found plenty of references to
parseParameters etc but nothing that I could say for definite were the
actual parameters.
Regards
