 These disadvantages can be avoided by using spatial models like indoor graphs. 
 Here, two main classes can be distinguished: symbolic and geometric spatial models \cite{Afyouni2012}.
 Especially geometric spatial models (coordinate-based approaches) are very popular, since they integrate metric properties to provide highly accurate location and distance information.
-One of the most common environmental representations in indoor localization literature is the Voronoi diagram \cite{Liao2003}. 
+One of the most common environmental representations in indoor localisation literature is the Voronoi diagram \cite{Liao2003}. 
 It represents the topological skeleton of the building's floorplan as an irregular tessellation of space. 
 This drastically removes degrees of freedom from the map, and results in a low complexity.
