A forest patterns map over a large extent at a high spatial resolution is a heavily computation task but is critical to most regions. There are two major difficulties in generating the classification maps at regional scale: large training point sets and expensive computation cost in classifier modelling. As one of the most well-known Volunteered Geographic Information (VGI) initiatives, Openstr...

This study developed a methodology for generating good alternative locations for road networks using heuristic solution techniques. Locations for road networks are determined based on road standards, timber harvesting and transportation costs, and topographic conditions. The main access road route is designed first and then single stand access roads are located as branches. A Genetic Algorithm ...

The effects of a forest road on Castanopsis carlesii (Hemsley) Hayata (Fagales: Fagaceae) seedlings and their leaf herbivory were investigated in a subtropical forest at Jiulianshan National Nature Reserve, Jiangxi, China. A total of 1124 seedlings, 33949 leaves, 468 leaf mines, and 205 leaf galls were found. Generally, individual numbers, tree heights, and leaf numbers of C. carlesii seedlings...

Management of bottomland hardwood sites requires adequate access to support forest operations. A study conducted in a bottomland forest in central Georgia has evaluated the effect of forest road design on sediment movement and water quality. Five years of measurement indicate that a conventional crowned road design is a net sir& for sediment, primarily due to settling in ditches. An alternative...

This paper focuses on an interdisciplinary approach using Geoinformation Science and Technology, Operations Research and Forest Science to overcome the limitations of the traditional forest road planning process. A pilot study shows that combining Geoinformation Science and Technology and Operations Research supports forest road planning. The first research objective solved in the project is th...

forest management as one of the important source of production is crucial and critical. in taking over the forest resources as one of the most important of natural resources in the world, it is essential to consider local stakeholders to implement forest action plan for forest co-management. therefore, this study aims at achieving to proper management of forests based on evaluating the stakehol...

After finishing my Ph.D. in Berkeley in 1971, I needed a job in the San Francisco Bay Area, while my wife was finishing her Ph.D. in statistics. It was a tough year jobwise and the only available position was a part-time job with the US Forest Service Station in Berkeley, which funded a position as a Research Engineer at the OR Center at UC Berkeley. My boss and friend up to today, Daniel Navon...
