How to create an interactive store map?

Question

Mobile devices

Hi all.
There is a task: to make information kiosks (or tablets) around the store with an interactive map of the hypermarket, where there would be a store layout, a buyer’s place (information kiosk location) and the ability to search for goods with displaying the path to it.
Who faced similar projects, or whom to contact for the development of this action - who knows?

Answer 1

How is this different from a regular site?
Chose a product, drew a path to the store?

Answer 2

Guys, no.
Given is a diagram of the store's internal shelving.
It is necessary to maintain a certain database so that you can change the location of goods inside stores, and based on this data, the scheme should draw a route - where to go for the client from the place where he is standing.
