UK utility data integration: overcoming schematic heterogeneity

In this paper we discuss syntactic, semantic and schematic issues which inhibit the integration of utility data in the UK. We then focus on the techniques employed within the VISTA project to overcome schematic heterogeneity. A Global Schema based architecture is employed. Although automated approaches to Global Schema definition were attempted the heterogeneities of the sector were too great. A manual approach to Global Schema definition was employed. The techniques used to define and subsequently map source utility data models to this schema are discussed in detail. In order to ensure a coherent integrated model, sub and cross domain validation issues are then highlighted. Finally the proposed framework and data flow for schematic integration is introduced

The Use of Geographical Information Systems in the Urban Communes of Łódź Metropolitan Area

The article presents the results of pilot studies carried out in the cities of Łódź Metropolitan Area. The study concerned the use of geographical information system by the employees of offices of these cities. The interest in the subject of GIS in Polish urban communes results from the assumptions of the EU INSPIRE Directive and the necessity of its implementation in the basic units of territorial division of Poland. The aim of the research was the analysis of the impact of GIS on the sphere of the public participation in the process of local management and the possible use of GIS in the decision making in communes. Research showed what kind of software was used in analyzed communes

Enhancing Coastal Resilience: Perspectives on Valuing RI Coastal Lands

This paper discusses coastal resilience as an organizing framework for future policymaking, coastal planning, and insurance decisions, and explores the different perspectives of the value of ecosystems held by various stakeholders in Rhode Island’s coastal communities. A grounded theory approach was used in an effort to abstract general insights from the substantive but isolated areas of coastal management and economics. Special attention is given to the perspectives of municipal decision makers, the National Flood Insurance Program, natural economists, and real estate developers. We have (1) conducted a statistical analysis of environmental spending of RI towns, (2) identified key models for ecosystem services valuation, (3) researched the major threats to coastal ecosystems, and (4) explored how the coastal resilience theme might shape the future of the coast. Elements of the study rely on the formulation and testing of hypotheses. However, the analysis was primarily a demonstration of the inter-disciplinary emergent thinking that this paper proposes will provide solutions for coastal communities’ most pressing issues. The framing question is how social, personal, and environmental goals align when coastal resilience is enhanced, and how stakeholders can utilize these new decision-making tools to achieve increased communication and a more accurate understanding of the perceived value of ecosystem services

Development of an intelligent interface for adding spatial objects to a knowledge-based geographic information system

Earth Scientists lack adequate tools for quantifying complex relationships between existing data layers and studying and modeling the dynamic interactions of these data layers. There is a need for an earth systems tool to manipulate multi-layered, heterogeneous data sets that are spatially indexed, such as sensor imagery and maps, easily and intelligently in a single system. The system can access and manipulate data from multiple sensor sources, maps, and from a learned object hierarchy using an advanced knowledge-based geographical information system. A prototype Knowledge-Based Geographic Information System (KBGIS) was recently constructed. Many of the system internals are well developed, but the system lacks an adequate user interface. A methodology is described for developing an intelligent user interface and extending KBGIS to interconnect with existing NASA systems, such as imagery from the Land Analysis System (LAS), atmospheric data in Common Data Format (CDF), and visualization of complex data with the National Space Science Data Center Graphics System. This would allow NASA to quickly explore the utility of such a system, given the ability to transfer data in and out of KBGIS easily. The use and maintenance of the object hierarchies as polymorphic data types brings, to data management, a while new set of problems and issues, few of which have been explored above the prototype level

Development of Geographical Information Systems Applications for Local Government Organizations: the Case of the Rhodes Municipality, Greece

The present recommendation summons up matter from a project in progress, concerning the possibilities and conditions of founding a Social Geographical Information System (GIS) in the Municipality of Rhodes. It is argued that, on the level of local societies and their self-administration, the importance of GIS can prove decisive for the rational management of resources and mainly for a better service of the citizens. Local governments, being that very institution at the closest possible relationship and contact with the resident-citizen, are called to cope with a constantly expanding spectrum of functions and services, often with insufficient infrastructures and limited resources. Today’s stage of the applied development of the GIS technology permits an overall arrangement and regulation of a series of functions that are important elements of everyday life in a city. In this sense, the use of GIS, although in the beginning seems as an “unnecessary luxury†for Greek administrational matters, can contribute in a creative way to the realization of the institutional role of local government organizations, to the accomplishment of the declared goals of each municipal authority but also to the saving of time and expenses. However, beyond the applications of GIS related to the improvement of a city’s functions, and which are the most frequent, there is a whole constellation of additional uses that are often downgraded or ignored. It is about those dimensions and applications, during which the GIS are utilized as an implement of social studies and search, as a mechanism of tendency diagnosis, as a starting point for awareness on the problems of urban areas and of their residents. It is the perspective and necessity of such applications that we are trying not to downgrade in the present, initial stage of development of a “Social GIS for the Municipality of Rhodesâ€. Our fundamental point of view is that no modern “leading-edge†technology, no advanced implement is by itself a panacea. It can simply assist the development procedures, when it is in the right hands and with the appropriate staff, information and infrastructure. Procedures that have finally reference to the level of central or local political choices but also to the disposition, dynamic or not dynamic, of the body politic for interference and action.

GEOGRAPHICAL INFORMATION SYSTEMS USED IN BUSINESS ENVIRONMENT

Communities are constantly in competition with one another to attract businesses. New and better ways to market a community constantly go through experimentation. One tool that has come to the forefront is the use of a geographic information system (GIS). Lately, more and more communities are adopting this tool for land use planning and for economic development planning. Geographical Information Systems (GIS) are used for inputting, storing, managing, analyzing and mapping spatial data. This article consider the role of each function that a GIS can play in economics: map economic data with a spatial component; generate additional spatial data as inputs to statistical analysis; calculate distances between features of interest;define neighborhoods around objects;introducing new data.Geographical Information Systems map, asset management, suitability analysis

Modelling and simulating change in reforesting mountain landscapes using a social-ecological framework

Natural reforestation of European mountain landscapes raises major environmental and societal issues. With local stakeholders in the Pyrenees National Park area (France), we studied agricultural landscape colonisation by ash (Fraxinus excelsior) to enlighten its impacts on biodiversity and other landscape functions of importance for the valley socio-economics. The study comprised an integrated assessment of land-use and land-cover change (LUCC) since the 1950s, and a scenario analysis of alternative future policy. We combined knowledge and methods from landscape ecology, land change and agricultural sciences, and a set of coordinated field studies to capture interactions and feedback in the local landscape/land-use system. Our results elicited the hierarchically-nested relationships between social and ecological processes. Agricultural change played a preeminent role in the spatial and temporal patterns of LUCC. Landscape colonisation by ash at the parcel level of organisation was merely controlled by grassland management, and in fact depended on the farmer's land management at the whole-farm level. LUCC patterns at the landscape level depended to a great extent on interactions between farm household behaviours and the spatial arrangement of landholdings within the landscape mosaic. Our results stressed the need to represent the local SES function at a fine scale to adequately capture scenarios of change in landscape functions. These findings orientated our modelling choices in the building an agent-based model for LUCC simulation (SMASH - Spatialized Multi-Agent System of landscape colonization by ASH). We discuss our method and results with reference to topical issues in interdisciplinary research into the sustainability of multifunctional landscapes
