[OSRM-talk] need help about profiles

Hello Joseba,

It is the car profile from develop branch. Nothing special in that sense.

Please check if the restriction is in your data, too.

Assuming that height restrictions are tagged like [1] you need to adapt way_function in the profile. First extract the maxheight:

local maxheight = way.tags:Find("maxheight")

This gives you a string that you need to parse. According to the wiki it can be given in several formats, i.e. meters, feet and inches, etc. You need to develop a function that gives a number to compare. E.g. normalize everything to meters. So, your code could like a bit like this:

local maxheight_value = -1;
if maxheight then
  maxheight_value = parse_maxheight(maxheight)
end

if maxheight_value >0 and maxheight_value < maxheight_threshold then
  return
end

Best regards,
Dennis
