Abstract. XML is accepted as a standard format for data exchange on the Web. XML security research has mainly been focused on textual documents since its origin. The previous works are not appropriate in the context of geographic data, which comprises spatial and non-spatial data. Controlling access to those data was a troublesome task because of proprietary and composite data formats of GISs and complex data structures of spatial database systems. Besides allowing flexible integration of geographic data, XML offers us methods to deploy access control for these systems. In this paper we propose an access control model for Web GIS, in which controlled access depends on spatial extents of geographic data, by employing XML, and XML-based 2D vector graphic format SVG. We show its utility in the domain of Internet Mapping into the application of public safety and disaster management for national and local governments.
A similar architecture, but focused on XML-based representation of spatial data, has been proposed in REF .
