Often the answer is right under your nose!

What's next for Major Roads of Puerto Rico

We can get all streets in Puerto Rico. Improved route-finding for the Island.

pr-roads's Issues

Milepost data?

One of the other big challenges I've seen is that after getting roads data loaded, is that a lot of locations in Puerto Rico are listed by linear reference along the highway, for example "Carr 150 KM 12.3" - and it would be good to know if there are any sources that can provide more info that can make those references more useful. I've found that in some cases they also reference Barrio or other geography which can be referenced via Census TIGER 'Place' layers, in some cases the highway of interest might only cross a small part of the barrio, which helps to tie it down. Ultimately, having a better way to tie road segments and KM posts together might help for geocoding and navigation apps.
