ABSTRACT
Recently we integrated geospatial data management with security and the semantic Web to develop a secure geospatial semantic Web. This chapter describes
306
our work in this area. The organization of this chapter is as follows. We discuss geospatial semantic Web in Section 23.2, including our research on the geospatial semantic Web as well as the Automatic Discovery of Geospatial Information Services (DAGIS) System we developed. The initial version of DAGIS was developed at the University of Texas at Dallas by Alam Ashraful, Ganesh Subbiah, Latifur Khan, and Bhavani Thuraisingham. We discuss secure geospatial data-management issues in Section 23.3. The secure geospatial semantic Web is discussed in Section 23.4. Secure interoperability of geospatial data is discussed in Section 23.5. Some aspects of GeoRSS are given in Section 23.6. The paper is concluded in Section 23.7.
