The OSRM distance table calculator is documented here...

https://github.com/Project-OSRM/osrm-backend/wiki/Server-api#distance-ta
bles

Basically you feed it a url with a bunch of lat/lon pairs are
parameters (say for the 10 largest cities in the area) and then it
creates a 10x10 table of the distances from every city to every other
city.  So we can duplicate the table in the top right corner of the
PDF, we just need someone to get the lat/lon of each of those cities
and feed them into the api call documented above.  If our distances
are signifigantly greater than the PDF distances listed for any
entries then that probably indicates a problem in our data on the road
between those cities.
