A GIS-Based Metropolitan Railway Planning Process

Ontology-based Railway Infrastructure Verification - Planning Benefits

Planning new railway infrastructures is a complex process. We present an approach where the formalization of expert knowledge regarding the railway domain is motivated in order to improve the planning process. By applying ontologies as a representation of railway related knowledge we are able to make the coherencies of infrastructural elements explicit. Furthermore the integration of an ontolog...

Solving railway line planning problems using a decomposition algorithm

The passenger line planning is a process of strategic long-term decision-making problem in the field of railway passenger planning. A line is a route between starting point and destination with certain stops, which has a certain frequency of train schedule. A new solution based on decomposition algorithm has been proposed in this paper, which is defined in a master problem and two sub problems....

GIS - based Flood Risk Analysis Across Large Metropolitan Areas

This paper examines the effects of urbanization on the flood hazard in semi-arid/arid southern California using traditional hydrograph, frequency-magnitude and statistical analysis augmented with GIS-based variable parameterizations and visualizations. It was found that the peak flood discharges were significantly increased in urban watersheds in conjunction with increasing mean baseflow in the...

Landscape planning and GIS-based data management

Landscape Planning in Germany is based on the recently amended nature protection law. Municipalities and districts are required to draw up plans that represent the status and the future development of nature and landscape. The quality of the plans mostly depends on the quality of the gathered data and the quality of ecological evaluation methods applied. Geomatics could support the planning pro...
