Geocoding An Intersection with Open Street Map data
Sometimes, geographic information is given as street intersections rather than GPS coordinates or street addresses with house numbers. Intersections can be geocoded with Google Maps (Limited free usage with API), ArcGIS (paid software) or other web services which parse text and return coordinates. If you are lucky, there may be a government geocoding service for free.
On the other hand, you can perform your own geocoding of intersections by taking advantage of the detailed Open Street Maps data accessed with osmdata.
