This Editorial lead paper for the Journal of Location Based Services surveys this complex and multi-disciplinary field and identifies the key research issues. Although this field has produced early commercial disappointments, the inevitability that pervasive location-aware services on mobile devices will emerge means that much research is needed to inform these developments. The paper reviews firstly: the science and technology of positioning, geographic information science, mobile cartography,

Geopositioning Location or position determination, or 'geopositioning', is a crucial technology for LBS, as is the contextual mapping of the natural and built environment. Invariably any LBS application must answer canonical questions such as 'where am I, the user', 'where is X, the target object, place, person', as well as more complex questions such as 'how do I go from A to B using a route optimised against certain criteria'? The first question requires the use of position determination technology (PDT) that is either carried by the person initiating the query, e.g. a GPS receiver, or is accessed over a network connection, e.g., as in the case of mobile phonebased positioning. The second question may be posed in several ways. In one mode this could be a question asked by a service provider, an employer, an emergency management worker, who wants to track or find an object or person for a range of reasons. This kind of query is dependent on both geopositioning and the availability of 'point of interest' databases. In another mode, this request may have been initiated by the object or person who needs help, or needs to receive information dependent on place. The third question answers the standard navigation query, and requires not only the positions of the two places/points 'A' and 'B', but also a knowledge of the possible routes between them and the points of interest in their neighbourhoods.
