Obtain latitude and longitude from address without the use of Google API

r geocoding

I am currently working on a large population-based database where it is required that I compute the distance between two addresses for each individual. My first train of thought was to obtain the latitude and longitude representing each address and then compute the distance. I used Google API's to obtain the latitude and longitude for these addresses via various packages in R (e.g. dismo). However Google has a restriction of 2500 requests in a 24hr period. I have about 300,000 addresses and by running 2,500/day, I will not be able to meet the deadline.

Would anyone have suggestions regarding other API's I could use to obtain the latitude and longitude using R?

Thank you.

I would recommend that you try the RDSTK package which interfaces with the Data Science Toolkit. It is available on github.

EDIT. To compute the Road Distance, I would recommend the Mapquest Directions API, which appears to have no preset limits as per this link. Let me know how it goes.
