In cable trench construction, one of the tasks for engineers is to select a suitable route to minimize construction cost and obstructions. This paper discusses the development of a Geographic Information Systems (GIS)-based Customized system to automate the process of optimum shortest path finding for routing of underground power supply cable between any two substations. It combines the spatial...

Safety and security and considered a critical issue in railways. Applying geographic information system (GIS) and Global Positioning System (GPS) in the railway becomes very important. Web-based GIS makes it easy to exchange information and create better public communication through the Web site. It helps to plan for a trip by checking train times, stations and different lines between stations....

Network Geographic Information System is a GIS based on Web technical standards and communication protocol of network , a product of Web technology and GIS technology, it is based on Internet / Intranet to provide users with information distributed in space, data sharing, exchange and cooperation. WebGIS make full use of network resources, a large scale to reduce costs and complexity of dealing...

ing the essential qualities that are useful for a given domain and grouping those objects with similar qualities is a powerful way of simplifying the computer representation of a problem. These essential qualities characterise the state and the behaviour of objects. Behaviour is defined by abstracting the essential operations that an object can perform and which can be performed on it. A vector...

Floods are one of the most dangerous and common disasters worldwide, and these disasters are closely linked to the geography of the affected area. As a result, several papers in the academic field of humanitarian logistics have incorporated the use of Geographical Information Systems (GIS) for disaster management. However, most of the contributions in the literature are using these systems for ...

This study focuses on the possibilities and the limits of a prospective GIS land cover modelling applied to two case studies (France and Spain). The methodology, based on available GIS tools, consists of using earlier land cover maps and relevant environmental factors (calibration data) to model actual, known land cover to validate the model. The model aggregates Markov chain analysis for time ...

This study proposes a geographic information system (GIS)-based cellular automata (CA) model, which is designed for planning bikeways upon existing footpath networks within an urban area. The CA model was developed based on GIS platform as visual interface whereby spatiotemporal characteristics and spatial processing can be combined in highly effective way. host value of each cell conditioned f...
