XML in service architectures for mobile cartographic applications

Abstract

XML-based methods are becoming increasingly important in the development of GI-related Web services. This chapter describes the use of XML techniques in the context of open, layered service architecture designed to support mobile cartographic applications. The XML solutions discussed include data modelling and validation, spatial data encoding and linking, data transformations and map visualisation. The technologies are introduced, their application in the GI domain further elaborated and the role of each technique within layered GI service architecture described. The responsibilities of each of the service layers in the proposed five-layer architecture are also discussed and the relevant, internationally accepted GI standards briefly introduced. Finally, as a case study the service architecture implemented in the GiMoDig project is presented. © 2005 Springer-Verlag Berlin Heidelberg.
