WE would like to develop an application to calculate road distance on server side using .NET. We need to compare road distance from Address A to various cities and identify nearest city. I am not sure if there is any Zip to Zip road distance database available. We need to process more than 100 records in a query so performance is critical issue even if we use very fast API unless they provide some way to calculate it in bulk using a single request.
Does anyone know a possible tool to explore that would make this task easier
I ended up using MapQuest API to achieve this. It seems really working well so far.
