Interoperable Exchange and Share of Urban Services Data through Geospatial Services and XML Database

Abstract

One of the most important criteria to have a comprehensive management is access to update and reliable data. Nowadays city management, as one of the aspects of management, is becoming more important and critical and in order to have a successful city management, reliable and update urban services data accessibility is one of the main issues. To be able to grant more efficient services to citizens it is necessary to utilize new methods of publishing and management of urban services data. This issue becomes more complicated where there are lots of users with distinct computing platforms and preferences. In this regards, using interoperable solutions to publish urban services data must be considered. . There are plenty of solutions to provide interoperability and the most widely used technologies in GI community are OGC services framework. In IT community, Service Oriented Architecture through Web services technologies provide the full potential of interoperability among heterogeneous computing platforms. In this regard, OGC services and Web services technologies are not directly compatible. Integrating OGC services and Web services enables us to provide fully interoperable solution. The underlying issue in integrating OGC services and Web Services is the predefined functionality inherent to the OGC services and the lack of any predefined functionality in the Web Services technologies. In order to publish urban services data, efficient data management and retrieval mechanisms, to provide highest possible performance and scalability, are needed. This paper is focused on evaluating two distinct data storage and retrieval approaches to compare performance and scalability. Afterwards this paper identifies the implementation issues of developing interoperable services and then proposes standard-based approaches to overcome these issues. This research concluded that coupling XML database systems with interoperable geospatial services is a standard-based and efficient solution for publishing urban services data.
