摘要： In implementations of the subject matter described herein, a solution for providing an indoor location-based service is provided. In this solution, a floor plan about a first floor of a first building comprising at least one floor is obtained. A first map for the first floor is generated based on the floor plan. The first map includes a plurality of vertices and edges, where one vertex corresponds to a position on the first floor, an edge connecting two vertices represents a physical object or a passable path on the first floor, and two positions corresponding to the two vertices are located at the physical object or on the passable path. Moreover, a location-based service is provided to a user at least based on the first map.
