We implement an algorithm that uses a system of fuzzy relation equations (SFRE) with the max-min composition for solving a problem of spatial analysis. We integrate this algorithm in a Geographical Information System (GIS) tool, and the geographical area under study is divided in homogeneous subzones (with respect to the parameters involved) to which we apply our process to determine the sympto...

Cluster detection is a tool employed by GIS scientists who specialize in the field of spatial analysis. This study employed a combination of GIS, RS and a novel 3DCCOM spatial data clustering algorithm to assess the rural demographic development strategies of Sonepat block, Haryana, India. This Study is undertaken in the rural and rural-based district in India to demonstrate the integration of ...

Geographical information systems (GIS) are becoming more prevalent in both day-today and strategic decision-making by retailers. Given the array of internal and external databases they use and integrate, and the human and organisational development needed, a most apposite description of how a GIS may be introduced for retailing decision-making is``system implementation''. There is little publis...

In the last 20 years, several conceptual data models specific for Geographic Information Systems (GIS) have been proposed. However, so far there isn’t a consensus model, which has generated several problems for the GIS area, such as the lack of interoperability among CASE tools that give support to these models. A UML profile, called GeoProfile, was proposed to standardize the task of geographi...

Crisis events have dramatic impact on human society, economy and our environment. Geographical information and intelligence play a key role in crisis management activities. However, the use of geographical information technologies in responsible government agencies has been mostly confined to single users, and within single agency. An interdisciplinary team from Penn State University (comprised...

TLA geographical information system (GIS) is a digitalised mapping process in which data from topographical maps, remote sensing satellite imagery, high-altitude photographs and other maps can be layered and analysed. GIS has been applied to a number of research disciplines because it is an effective means of relating data to geography. An important advantage of using GIS is that layers of unre...

The application of GIS to the forecast and evaluation in the regional landslide can provide scientific basis for the regional geological environment management and the geological disaster assessment, can integrate the scattered data to share each other, and can improve data value. Its powerful interface function library provides a good tool for the professional GIS design and development. This ...

We introduce SIGTERNET (named before e-Edita) which is a tool to build, manage and query Geographical Information Systems (GIS) by the Internet in a client-server architecture. The system has evolved from a project designed in 1996 to establish links between spatial and alphanumeric information. The project was reformulated in 2006 to meet the GIS art of state systems. One of the most important...

GIS research has a continuing threaddevoted to classifying the operations performed by analytical software. Prior e€ orts to classify GIS operations have limitations and inconsistencies, often arising from an attempt to establish overly direct links between geographic procedures and arithmetical operations. The transformational view of cartography provides a more solid basis for classifying GIS...

The project aims to develop, test and apply a Geographical Information System (GIS) for modelling access for wheelchair users in urban areas. The principal focus is to provide a GIS system that will work as a decision support and mapping tool for urban planners. In addition, the system has been designed to encompass future developments, including use as a guidance device to help wheelchair user...
