Common queries regarding information processing in ubiquitous
computing are based on the location of physical objects. No matter
if the next printer, next restaurant, or friend is searched for, a
notion of distances between objects is required. A search for all
objects in a certain geographic area requires the possibility to
define spatial ranges and spatial inclusion of locations. In this
paper we discuss general properties of symbolic and geometric
coordinates. Based on that, we present an overview of existing
location models allowing for position, range, and nearest neighbor
queries. The location models are classified according to their
suitability with respect to the query processing and the involved
modeling effort along with other requirements. Besides an overview
of existing location models and approaches the classification of
location models with respect to application requirements can assist
developers in their design decisions.
