The needed data can be very different and depends on the kind of services offered, that is on its global or specialized application character.

Purpose Specific LBS Applications are for instance services which help localizing handicapped people or services provided by a national park. For the first example, monitoring handicap people, only the position and mapping data is necessary, to show the patient position on map) the patient. Further the monitoring service could introduce (own) risk zones where an alert is activated if the patient enters the zone. For the second example, a national park LBS, again some background data for positioning information is useful. Such mapping data could be obtained from the country mapping agencies. Other national park services which answer questions like: What kind of tree is it? and Where to find an owl? will probably be in the park own information data bases. Additional information could be provided by an electronic encyclopaedia system of a publishing company.
