Outlier detection in relational data: a case study in geographical information systems KU Leuven
Geographical information systems are commonly used for a variety of purposes. Many of them make use of a large database of geographical data, the correctness of which strongly influences the reliability of the system. In this paper, we present an approach to quality maintenance that is based on automatic discovery of non-perfect regularities in the data. The underlying idea is that exceptions to these regularities ('outliers') are considered ...
Efficient use of geographical information systems for improving transport mode classification Universiteit Gent
Comparison between transport mode classifiers is usually performed without considering imbalanced samples in the dataset. This problem makes performance rates, such as accuracy and precision, not enough to report the performance of a classifier because they represent a cut-off point in the classifier performance curve. Our rule-based method proposes to combine both, the network elements associated with the transport mode to identify, and the ...
Application of remote sensing and geographical information systems in flood management : a review Universiteit Gent
Floods are one of the most widely distributed hazards around the world and their management is an important issue of concern among all the stakeholders. The aim of this review is to synthesize the state of art literature in the application of Geographical Information Systems (GIS) and Remote Sensing (RS) techniques in all the flood management stages (pre-flood, during flood and post-flood stages). Flood types and common concepts in flood ...
Sustainable waste-to-energy plant site selection by a hybrid method of geographic information system and evidential reasoning : a case study Guilan province Universiteit Gent
A new hybrid method of utilizing Evidential Reasoning (ER) approach and Geographic Information System (GIS) was applied to find the optimum location of a Combined Heat and Power (CHP) incineration plant in Guilan province. According to guidelines and prevailing conditions, thirteen criteria were analyzed and divided to three main sections of environmental, social and economic categories. Most of the data in the study were obtained from local ...
Upgrading geographic information systems to spatial decision support systems KU Leuven
A GIS is capable of identifying a set of land units meeting positional, temporal, topological and multiple on-site attribute criteria. Based on the combination of its generic analytical functionalities, a GIS can also be used to rank the alternative land units and propose the best or worst ones in terms of the non-weighted or weighted criteria. More advanced multi-criteria decision methods are however not easily incorporated in the GIS-framework ...
Unraveling hidden possibilities for a modal shift: A computational approach combining agent-based modeling and geographic information systems. Universiteit Hasselt
Purpose Synchromodal transport incorporates real-time events in a dynamic manner in order to facilitate the most suitable selection of modes, routes and handling points. Up until now, current modeling approaches that focus on the dynamic context of synchromodal transport make use of analytical models. Most of these models average distances for barges and trains via route mapping platforms that provide realistic distances for road only. To ...
Ambient air quality does not affect disease course in inflammatory bowel disease - a population based risk factor analysis using geographic information systems Universiteit Hasselt
Modal choice in freight transport: combining multi-criteria decision analysis and geographic information systems Vrije Universiteit Brussel
To tackle the modal choice decision problem in container transport, a decision support model for comparing intermodal and unimodal road transport is developed, using a combined multi-criteria decision analysis – geographic information system approach. Multi-criteria decision analysis allows to simultaneously analyse many, possibly conflicting, modal choice criteria. First, a geographic information system-based model calculates the size or the ...
