Sustainable forest planning and management require accurate and precise information about the estimation of forest resources. In particular, two tree parameters are very important among the others: diameter-at-breast height (DBH) and height that are used to estimate the volume and biomass of the tree. With the development of Remote Sensing (RS), in...
Cultural heritage (CH), what we inherited from the past generations, is a precious asset connecting the past to the present. It has many demonstrable benefits to nations around the world. For many countries, it has been a part of national identity as well as a key driver of the economy. However, CH is under constant threat of demolition due to wars...
An accurate tree diameter (DBH) measurement is a significant component of forest inventory. This study assessed the reliability of remote dendrometers to measure tree DBH. We compared direct caliper measurements (reference measurements) to the remote measurements collected from a laser caliper and a smartphone at 0.5 m, 1 m, and 1.5 m distances fro...

Urban trees and forests are essential components of the urban environment. They can provide numerous ecosystem services and goods, including but not limited to recreational opportunities and aesthetic values, removal of air pollutants, improving air and water quality, providing shade and cooling effect, reducing energy use, and storage of atmospher...
In fighting against forest fires, it is crucial for the ground-based firefighting team to reach a fire area in critical response time in which the chance of controlling the fires is significantly high. Road networks are the key infrastructures that provide access to the forest areas for the protection of forest resources. In order to benefit from t...
Nowadays, as in many sectors, natural and cultural resources face the danger of extinction due to misuse and consumption-oriented life in tourism. Within the framework of the sustainability tourism principle, these resources should be determined, protected, and developed. With the advance technology, the use of photogrammetry offers new methods for...
More than half of the total world’s population lives in urban areas, and it is expected that 66% of all them will live in urban areas by 2050. The population growth and continuing urbanization in the world cause many social, economic, technical, and organizational problems related to transportation, businesses, communication networks, services, and...
Nowadays, tourism which is one of the biggest and fastest developing sectors in the world,
can cause both positive and negative changes on the environment. Therefore, implementation
of sustainable tourism is important in the sector. Sustainable tourism aims to provide longterm utilization opportunities for natural and cultural resources, and to ens...

Forest road networks play an essential role to access forested areas, where biodiversity and natural resources are abundant, for forest planning, management, and protection activities. In recent, the effect of forest road networks are important elements for visual quality in particular managing and planning protected areas. In this context, while d...
Urban vegetation is an important resource in built up environments, and estimation of urban canopy cover arising from trees and shrubs is an important metric in assessments of landscape quality. We used an image classification approach to estimate urban vegetation cover consisting of trees and shrubs only within two medium-sized cities in the Unite...
The recreational opportunities available across landscapes of the Southern United States can be broad and diverse, and collectively are considered a subset of cultural ecosystem services. In describing the settings of recreational opportunities, a number of methods have been proposed that are based in part on geographic information and that can be...
Linear programming is often used for the development of forest plans; however, the models designed usually lack the spatial detail and associated constraints (e.g., harvest adjacency) necessary for contemporary tactical forest planning processes. To accommodate spatial constraints, a linear problem is often transformed into a mixed-integer linear p...
We present an analysis framework composed of a geospatial process that can be employed to identify suitable areas for increasing the supply of biomass material on landscapes that include a large number of private landowners. Our analysis estimated bare land and a broad open land class, and considered restrictions on bioenergy projects pertaining to...
The static horizontal position accuracy of a mapping-grade GPS receiver was tested in two different pine forest conditions (pre-thinning and post-thinning of a 20-year old loblolly pine (Pinus taeda) stand). The main objective of this study was to describe the horizontal position error that might be observed shortly before and shortly after a thinn...
The field of forestry has employed various computer-assisted optimisation approaches since the early 1960s to address the efficient allocation of resources towards various forest management objectives. These approaches continue to evolve, and in the last 5 years, the research has expanded to demonstrate how complex, non-linear relationships can be...
Two different sampling approaches for estimating urban tree canopy cover were applied to two medium-sized cities in the United States, in conjunction with two freely available remotely sensed imagery products. A random point-based sampling approach, which involved 1,000 sample points, was compared against a plot/grid sampling (cluster sampling) app...
The static horizontal position accuracy of a mapping-grade GNSS receiver was tested in two forest types over two seasons, and subsequently was tested in one forest type against open sky conditions in the winter season. The main objective was to determine whether the holding position during data collection would result in significantly different sta...
The ability to measure trees remotely or at a distance may be of value to forest inventory processes. Within three forest types (young coniferous, old coniferous, and deciduous), we compared laser caliper measurements collected at distances up to 12 m from each tree, to direct contact caliper measurements. Bitterlich sector-fork measurements and di...

In this project, it is aimed to investigate the effects of improving forest road standards on expanding accessible forest areas within the critical response time, especially in forests with high fire risk, and thus reducing potential wood raw material losses. In the study, a fire risk map will be developed using a Geographical Information System (GIS) based mathematical model (Fuzzy Logic) to identify forest areas with high fire risk. Antalya Forestry Regional Directorate, where forest fires are seen most frequently and the amount of burned area is the highest in Turkey, is selected as the study area as one of the forest regional directorates where forest fires are seen most frequently and the amount of burned area is the highest in Turkey. In the solution process, primarily the forest areas that can be reached by the firefighting team (including mobile teams used in emergencies) within the critical response time will be determined by considering the existing road network in the study area. Then, the possible increase in the accessible forest areas with high fire risk will be investigated if the road standards are improved. Network analysis-based GIS techniques will be used to determine the forest areas that firefighting team can reach within the critical response time.
Two scenarios will be compared in terms of potential economic consequences of improving forest road standards. In the first scenario, annual major repair costs of existing forest roads will be calculated based on unit costs. In the second scenario, the cost of road improvement activities (road construction, road structures, road surface construction within the scope of major repairs) and annual maintenance costs will be calculated based on unit costs. Then, the economic value of the wood raw materials in the additional forest areas, which can be accessed by improved road standards in the second scenario will be determined according to the stand characteristics, amount of product, product type, and their unit prices. Finally, the net present value of the economic results will be calculated by considering total road costs and economic value of the wood raw material determined in the second scenario.
