Looking for a API/Solution for a detailed maps app
I am searching for a Maps or similar API/solution to map a very small market area. This would need accuracy of around 1 'real' meter to be able to show each vendor on our market.
Would anybody have an idea of such low level maps application which would make the presentation of small area clear with API possibility?
Another addition to this is to have leveled maps application - at the same detail - to show market with 2 levels or more.
All opinions highly appreciated!
