The design and implementation of a repository for the management of spatial data integrity constraints

This paper reviews the key features of an environment to support domain users in spatial information system (SIS) development. It presents a full design and prototype implementation of a repository system for the storage and management of metadata, focusing on a subset of spatial data integrity constraint classes. The system is designed to support spatial system development and customization by users within the domain that the system will operate.

Incorporating level set methods in Geographical Information Systems (GIS) for land-surface process modelling

Land-surface processes include a broad class of models that operate at a landscape scale. Current modelling approaches tend to be specialised towards one type of process, yet it is the interaction of processes that is increasing seen as important to obtain a more integrated approach to land management. This paper presents a technique and a tool that may be applied generically to landscape processes. The technique tracks moving interfaces across landscapes for processes such as water flow, biochemical diffusion, and plant dispersal. Its theoretical development applies a Lagrangian approach to motion over a Eulerian grid space by tracking quantities across a landscape as an evolving front. An algorithm for this technique, called level set method, is implemented in a geographical information system (GIS). It fits with a field data model in GIS and is implemented as operators in map algebra. The paper describes an implementation of the level set methods in a map algebra programming language, called MapScript, and gives example program scripts for applications in ecology and hydrology.

On aggregation issues in spatial data management

Large amounts of information can be overwhelming and costly to process, especially when transmitting data over a network. A typical modern Geographical Information System (GIS) brings all types of data together based on the geographic component of the data and provides simple point-and-click query capabilities as well as complex analysis tools. Querying a Geographical Information System, however, can be prohibitively expensive due to the large amounts of data which may need to be processed. Since the use of GIS technology has grown dramatically in the past few years, there is now a need more than ever, to provide users with the fastest and least expensive query capabilities, especially since an approximated 80 % of data stored in corporate databases has a geographical component. However, not every application requires the same, high quality data for its processing. In this paper we address the issues of reducing the cost and response time of GIS queries by preaggregating data by compromising the data accuracy and precision. We present computational issues in generation of multi-level resolutions of spatial data and show that the problem of finding the best approximation for the given region and a real value function on this region, under a predictable error, in general is "NP-complete.

A composite framework for the strategic alignment of information systems development

Information systems are corporate resources, therefore information systems development must be aligned with corporate strategy. This thesis proposes that effective strategic alignment of information systems requires information systems development, information systems planning and strategic management to be united. Literature in these areas is examined, breaching the academic boundaries which separate these areas, to contribute a synthesised approach to the strategic alignment of information systems development. Previous work in information systems planning has extended information systems development techniques, such as data modelling, into strategic planning activities, neglecting techniques of strategic management. Examination of strategic management in this thesis, identifies parallel trends in strategic management and information systems development; the premises of the learning school of strategic management are similar to those of soft systems approaches to information systems development. It is therefore proposed that strategic management can be supported by a soft systems approach. Strategic management tools and techniques frame individual views of a strategic situation; soft systems approaches can integrate these diverse views to explore the internal and external environments of an organisation. The information derived from strategic analysis justifies the need for an information system and provides a starting point for information systems development. This is demonstrated by a composite framework which enables each information system to be justified according to its direct contribution to corporate strategy. The proposed framework was developed through action research conducted in a number of organisations of varying types. This suggests that the framework can be widely used to support the strategic alignment of information systems development, thereby contributing to organisational success.

An institutional perspective on management accounting change in the public sector : a case study from Canada

This thesis reports on a four-year field study conducted at the Saskatchewan regional office of the Department of Indian Affairs and Northern Development, a large department of the Government of Canada. Over the course of the study, a sweeping government-wide accounting reform took place entitled the Financial Information Strategy. An ethnographic study was conducted that documented the management accounting processes in place at the regional office prior to the Financial Information Strategy reform, the organization’s adoption of the new accounting system associated with this initiative, and the state of the organization’s management accounting system once the implementation was complete. This research, therefore, captures in detail a management accounting change process in a public sector organization. This study employs an interpretive perspective and draws on institution theory as a theoretical framework. The concept of loose coupling and insights from the literature on professions were also employed in the explanation-building process for the case. This research contributes to institution theory and the study of management accounting change by recognizing conflicting institutional forces at the organizational level. An existing Old Institutional Economics-based conceptual framework for management accounting change is advanced and improved upon through the development of a new conceptual framework that incorporates the influence of wider institutional forces, the concepts of open and closed organizational systems and loose coupling, and the recognition of varying rates of change and institutionalization of organizational activity sets. Our understanding of loose coupling is enhanced by the interpretation of institutional influences developed in this study as is the role of professionalization as a normative influence in public sector organizations.

About Methods of Mathematical Modelling in the Development of Information Systems

This article describes the approach, which allows to develop information systems without taking into consideration details of physical storage of the relational model and type database management system. Described in terms of graph model, this approach allows to construct several algorithms, for example, for verification application domain. This theory was introduced into operation testing as a part of CASE-system METAS.

Information Technologies for Strategic Management

Strategic management is a special kind of managerial activity dealing with long-term development and growth of the enterprise. Therefore it has specific information needs and uses various information technologies different than used in the operational and middle-level management processes. In the current paper we present an information technologies' classification according to the phases of strategic management process and extract these information technologies which are of crucial importance for the successful strategic management.
