Download or read book Programs for Road Network Planning written by Ward W. Carson and published by . This book was released on 1978 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes four computer programs developed to assist logging engineers to plan transportation in a forest. The objective of these programs, to be used together, is to find the shortest path through a transportation network from a point of departure to a destination. Three of the programs use the digitizing and plotting capabilities of a programable desk-top calculator system to conveniently enter and store a numerical description of the network to he analyzed. The fourth program solves the problem by an efficient optimization algorithm. The BASIC language programs are described through an example problem, and complete listings are provided.

Available in PDF, EPUB and Kindle. Book excerpt: Forest roads can potentially cause environmental impacts, especially related to water dynamics and sediment production. To identify critical areas for forest road allocation, we considered landscape criteria such as slope, erodibility (K), distance to accumulated water flow, and aspect. The multicriteria evaluation method combines these criteria and produces a spatial map of critical areas for road allocation in a planted forest farm. The Receiver Operating Characteristic analysis supported the verification of map accuracy. The map indicated that around 40% of the farm had a high criticality level, and 30% had an average level. The current roads were associated with different levels of criticality: 37.79% were considered high, 21.78% were average, 17.43% were low, 15.23% were very high, 6.97% were very low, 0.43% were extremely low, and 0.36% were extremely high. The accuracy of the map was statistically significant, suggesting an appropriate representative of the landscape aspects. Therefore, we concluded that using the MCE method to aggregate criteria supports forest road network planning by incorporating landscape characteristics.

This book was released on 2018-06-20 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first part of the Manual introduces the main steps of forest road network planning and gives guidance on road construction under different site conditions. It demonstrates good practices to minimize the area used for building purposes, to keep the environmental impact as low as possible and to maintain forest productivity. It describes the machinery suitable for the different construction phases and compares the advantages of machine types. The second part of the Manual introduces the goals and best practices of regular forest road maintenance which is a key operation that enables multi-purpose use of forests. It gives an overview on the main causes of forest road degradation and explains the different maintenance regimes and maintenance activities.
Download or read book A Weighted Graph Optimization Approach for Automatic Location of Forest Road Networks written by Jürg Andreas Stückelberger and published by vdf Hochschulverlag AG. This book was released on 2008 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a large majority of regions where forestry activities occur, roads are the backbone of their efficient management. Automatic planning of a road network is an ongoing, challenging task. Advances have been aided by the increased availability and accuracy of digital terrain models, greater computing power, and improvements in optimization techniques. Defining the objectives and deriving adequate objective functions are crucial steps in guiding the solution toward an ideal network, especially when individual goals may conflict. For example, whereas the conservationist might prefer that a layout minimizes any detrimental impacts on the environment, the forest landowner may favor cost-minimal roads while the forest operator would like to have a dense network in order to reduce transportation costs.This thesis introduces models for three objective functions: - forest road construction and maintenance costs, - negative ecological effects from such roads, - the suitability, or attractiveness, of a network for cable-yarding.Case studies in mountainous project areas illustrate the trade-offs among these conflicting goals, and demonstrate how to optimize different objectives in order to make an optimal decision overall.

This book was released on 2019-01-18 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial Modeling in GIS and R for Earth and Environmental Sciences offers an integrated approach to spatial modelling using both GIS and R. Given the importance of Geographical Information Systems and geostatistics across a variety of applications in Earth and Environmental Science, a clear link between GIS and open source software is essential for the study of spatial objects or phenomena that occur in the real world and facilitate problem-solving. Organized into clear sections on applications and using case studies, the book helps researchers to more quickly understand GIS data and formulate more complex conclusions. The book is the first reference to provide methods and applications for combining the use of R and GIS in modeling spatial processes. It is an essential tool for students and researchers in earth and environmental science, especially those looking to better utilize GIS and spatial modeling. Offers a clear, interdisciplinary guide to serve researchers in a variety of fields, including hazards, land surveying, remote sensing, cartography, geophysics, geology, natural resources, environment and geography Provides an overview, methods and case studies for each application Expresses concepts and methods at an appropriate level for both students and new users to learn by example
Download or read book Optimization of Forest Roads Network in Hilly and Mountainous Natural Forests in Northern Bosnia and Herzegovina written by Vladimir Petković (gozdar) and published by . This book was released on 2019 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable forest management requires optimization of forest roads network. Optimization from the point of utilization of timber implies determination of optimal density and spatial layout of forest roads, and at the same time, it is necessary to justify social, cultural and protective forest functions and spatial management. The public natural forests of Northern Bosnia and Herzegovina (BIH) were object of observation and research, and they are naturally renewed from the seeds. It is the most important forest category from the point of quantity and quality of timber and biodiversity. The overall forest accessibility of forests in BIH is 10 m/ha, and density of forest roads in natural forests is 11 m/ha. These forest accessibilities are insufficient for sustainable forest management from the aspect of Forest % (1995) recommendations. Such state of overall and natural forests accessibility requires planning of new forest roads. Planning of new forest roads consists of planning of forest accessibility and designing of forest roads. This task requires analysis of actual forest roads network, determination of optimal density of forest roads, determination of suitability of forest area for the construction of forest roads and designing of forest roads in the end. Actual forest roads network analysis includes determination of forest road density, average skidding distance, relative forest accessibility and coefficient of efficiency of actual forest roads network. These indicators of forest accessibility are used for assessment of quantity and quality of actual forest roads network. Analytic Hierarchy Process (AHP) allows selection and evaluation of influential factors in relation to planning of forest roads. The tools of Geographic Information System (GIS) allow a complete spatial and statistical analysis and management of data collected from the forest management plans or being surveyed in the field, and obtained by analysis of Digital Terrain Model (DTM) and AHP method. Planning of forest roads was done in hilly Management Unit (the MU) Prosara and mountainous MU Bobija-Ribnik. Optimal density of forest roads was determined by minimization of total transportation cost, it ranges from 16 to 26.5 m/ha. These results showed that natural forests have potential for normal forest management.
