I'm currently working on a map with stores and clients. I want to find the closest store by road from a given client, with the aim of simulating the creation of a new store.
- precision is not an issue (low quality data is OK)
- free or cheap (no 100000$ GIS solutions...)
Of course I could use google maps api and try every store. But I have a lot of stores and clients, and I would like to run the simulation several times, so it would sent far too many queries.
