A Spatial Data Infrastructure (SDI) facilitates and coordinates the exchange and sharing of spatial data between stakeholders in the spatial data community. With this objective in mind, countries throughout the world are developing SDIs to manage and utilise their spatial data assets more effectively. These countries are developing SDIs to assist in various kinds of decision-making at different...

The complex and proprietary nature of geospatial data makes them almost non-sharable among large user community. GIS interoperability is necessary for realizing a successful spatial data infrastructure. With the advancements of web service technology, GIS interoperability has made a paradigm shift – from monolithic GIS providers to distributed geospatial services. The applicability of web servi...

Many organizations today are require information from diverse information systems, and government efforts are moving towards a National Information Infrastructure for sharing information. However, the systems used by these organizations lack the capabilities to meaningfully translate information between semantically heterogeneous environments. Because the meaning of data acquired from a source ...

The Internet provides tremendous connectivity and information sharing capability which organizations can use for their competitive advantage. However, we still observe security challenges in Internet-based applications, especially in terms of their limited support for controlled access to organizational resources and information for unknown users. Roles can be a convenient construct for express...

The perception of geographic information system and spatial data infrastructure in the developing societies is vague. Developing societies in the context of this paper are societies that are disadvantaged in the provision of geographic information system and spatial data infrastructure. The notion is that there is no clear cut understanding of geographic information system and spatial data infr...

Although trust is recognized as important in security issues of computer networking environments, few studies on information systems deal with both trust and security, and those existing tend to remain within the short perimeter of two-agent interactions. We propose to rethink trust research on information system security by considering the holistic approach of critical infrastructure protectio...

The paper presents the core concepts of the Polish Spatial Information System, reflecting the results of investigations performed within the framework of the research project conducted at the Institute of Geodesy and Cartography. The architecture of the Polish Spatial Data Infrastructure with regard to data flow and data access is presented. Describing the System the author stresses the importa...

As municipalities increasingly rely on computer-based systems and data management, information that was traditionally exchanged through human communications can now be exchanged electronically through computer-to-computer data exchange. This requires much more formal specifications and agreements to govern these data exchanges. The main purpose of the paper is to identify the current state of i...
