1. Random walks and Electrical networks Let G be a connected, undirected graph on n vertices, and let s and t be any two distinct vertices of G. For any vertex v of G, let pv denote the probability that a random walk on G starting at the vertex v will visit s before visiting t. (Using a more picturesque language, imagine that G represents a map of some city. A drunken tourist is trying to get t...

rivers are important water resources for human life, but sometimes cause irreparable damages. the flood plains are fertile terrains which are endangered by flood. flood hazard mapping is one of the basic methods in flood fighting. in order to decline flood damages, the simulation of the hydraulic behavior of the rivers during flood occurrence is very important. in this study, areas that are flo...

The aerial photos of Aquileia, especially the orthophotos of the last decade, allow for a new and broad vision of the ancient city’s extent. Together with V.Roberto we published some new findings. More recent orthophotos (2010), after data filtering and image processing, allow for newer insights into the roman city map .

Virtual city models are increasingly used in urban land management processes, which involve the use of different sources of spatial information. This heterogeneous data is, however, often complementary and it may be necessary to give the possibility to join information provided by different sources. This paper presents a method to enhance 3D buildings by using usual 2D vectorial polygon databas...

This introductory chapter explores notions of the Digital City through four action types relating to complimentary levels of function and contends that geovisualization is a key component. An interdisciplinary and international workshop on GeoVisualization and the Digital City is reported upon and the process developed for supporting an stimulating cross-disciplinary research and publication in...
