RESUMO

Location-Based Services (LBS) are services which use geographic information to obtain and generate useful information for users such as the location of the nearest gas station, for instance, or the best route for the nearest hospital by taking the user s current position as a starting point. There are several initiatives for the definition of standards aiming at increasing the interoperability of applications, which are based upon location services. Among the main initiatives, the Open Location Services (OpenLS) of the Open Geospatial Consortium (OGC), and Mobile Location Protocol (MLP) of the Open Mobile Alliance (OMA) should be mentioned. The use of the Web Services technology is also a way to assure the interoperability involving LBS applications, once it allows applications in different platforms and programming languages to communicate via XML or other Web standards. This dissertation is aimed at presenting a study regarding the technologies involved in the development of Location-Based Services and proposing an architecture which is based on open standards to make these services available. This architecture is validated through the development of a prototype of the Presentation Service defined in the OpenLS specification. This study also comprises an analysis of some market-available products that offer LBS applications that use open standards
