 Here is a typical informal gloss for ‘is exactly located at’: an entity x is exactly located at a region y if and only if x has (or has-at-y) exactly the same shape and size as y and stands (or stands-at-y) in all the same spatial or spatiotemporal relations to other entities as does  y.[1]  Thus, small cubes are exactly located only at small cubical regions, large spheres are exactly located only at large spherical regions, and so on (see Casati and Varzi 1999: 119–120; Bittner, Donnelly, and Smith 2004; Gilmore 2006: 200–202; Sattig 2006: 48).
