A Graph Theory Approach to Road Network Generalization
Robert C Thomson & Dianne E Richardson Canada Centre for Remote Sensing MSD, 4th Floor, 588 Booth Street Ottawa, Ontario KIA OY7, Canada fax: (613) 9471383 The development of techniques for the automatic integration of remotely sensed data into a GIS environment is one focus of research at Canada Centre for Remote Sensing. One aspect of this effort is the automatic creation of databases of geog...
متن کاملAn Evaluation of Space and Graph-partitioning Methods for Distributed Road Network Simulations
We evaluate three different approaches to road network partitioning for simulation. The first approach consists of algorithms that rely on dividing the road physical network spatially into rectangular blocks of different sizes. Our second approach uses a graph representation of the road network, and uses meta-heuristic search algorithms to partition the graph. The final hybrid scheme builds clu...
متن کاملComputational Investigation on Structural Properties of Carbon Nanotube Binding to Nucleotides According to the QM Methods
The interaction between nucleotides and carbon nanotubes (CNTs) is a subjectof many investigations for treating diseases but there are many questions in this field thatremain unanswered. Because of experimental methods involve assumptions andinterpretation besides limitations, there are many problems that the best study for them isusing theoretical study. Consequently, t...
متن کاملClassification of Protected Forest Areas for Road Network Planning (Case Study: Arasbaran Area)
The road network is an important element for sustainable forest ecosystem management. On the other hand, efficiency and quality of road design can be improved by considering of environmental and technical principles. Therefore, this study was performed to determine the capability of Arasbaran protected area for road passing and communication routes in order to use in the area management. For th...
متن کاملInvestigation of forest road surface sediment estimation using two experimental models of SEDMODL and WARSEM
Extended abstract 1- Introduction A bare surface on forest roads is created due to road construction. This surface is the main source of erosion and sediment yield to streams in forest areas. The increase of sediment in streams causes dramatic damage to the quality of water ecosystems and the life of aquatic organisms. Therefore, road engineers should pay attention not only to the cost of roa...
متن کاملCharacterizing the hierarchy of road network and its landscape effect with graph theory∗
Roads are conspicuous components of landscapes and play a substantial role in defining landscape pattern. Previous studies have demonstrated the link between roads and their effects on ecological processes and landscape patterns. Less understood is the relationship between landscape patterns imposed by the network in relation to road network configuration, spatial heterogeneity etc. Our hypothe...
