Book review: Networks and Algorithms

This book tells you the difference between the various types of graphs, trees and networks and shows you step by step calculations on how to solve them by hand (they didn’t have that many computers in 1993).

How to make a straight line square

Traditionally, network analysis, path finding and route planning have been the domain of graph theory and vector GIS, which is where most algorithms find their application. Contrary to such common wisdom, the research of this thesis for the Msc in GIS explores the topic of network analysis in raster GIS, using MFworks as example software.

Fastest path problems in dynamic transportation networks

This research essay and literature review investigates some of the gateways to path finding in static and dynamic networks that are listed in present research literature. A selected set of different approaches are highlighted and set in a broader context, illustrating the various aspects of path finding in static and dynamic networks.

Network analysis – raster versus vector – A comparison

The key to producing successful network models is in understanding the relationship between the characteristics of physical network systems and the representation of those characteristics by the elements of the network model.
