Ok... I've been using MapQuest to calculate miles for an application we have and it appears to be working very well. I think we've successfully queried for about 8,000 trips. However, I have a handful of these trips where MapQuest returns a status code other than 0. I believe 602 is one of the status codes that was returned. Where can I find the documentation on what the status codes mean so I can figure out if there is something we could do on our side to avoid these invalid codes?
While it's impacted only about 15 rides, it looks like there are only 5 locations that caused these error codes so if I can figure out what's wrong with those lat/lons, I think I can clean these up.
