For our application, we need to get all the US interstate highway exits along with their Geocodes. Can you please explain how to get these using Google Maps API or Google Local search or otherwise? So far I have no clue as to how to proceed.
I am looking for a free or a paid solution that is around $1000. I know there are people who provide geocodes. But they are out of our budget.
Several people are suggesting TIGER data with ArcGIS. I know nothing of them.
