Fireanalyst: An Effective System For Detecting Fire Geolocation And Fire Behavior In Forestsusing Mathematical Modeling, Yücel Güllüce, Rahmi̇ Nurhan Çeli̇k
Turkish Journal of Agriculture and Forestry
This study proposes an effective new fire detection method and monitoring software for an early-warning fire detection system aimed at valuable forested areas, such as botanical parks or high conservation value forests, particularly those with boundaries. These critical forested areas need to be appropriately managed because they contain large concentrations of biological diversity, including threatened or endangered species, which are very susceptible to fire outbreaks; thus, early detection of fire and rapid response have a very important place in the fight against fire in those areas. In this proposed system, special detectors with state-of-the-art multispectral infrared technology and mathematical modeling …
Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover
Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover
Journal of Geospatial Applications in Natural Resources
Landforms control the spatial distribution of numerous factors associated with agronomy and water quality. Although curvature and slope are the fundamental surface derivatives used in landform classification procedures, methodologies for landform classifications have been performed with other terrain indices including the topographic position index (TPI) and the convergence index (CI). The objectives of this study are to compare plan curvature, the convergence index, profile curvature, and the topographic position index at various scales to determine which better identifies the spatial variability of soil phosphorus (P) within three low relief agricultural fields in central Illinois and to compare how two methods …
Land Suitability Assessment For Rice Cultivation Based On Gis Modeling, Orhan Dengi̇z
Land Suitability Assessment For Rice Cultivation Based On Gis Modeling, Orhan Dengi̇z
Turkish Journal of Agriculture and Forestry
The main objective of this study was to develop a spatial model for land suitability assessment for rice (Oryza sativa L.) cultivation using geographic information system (GIS) techniques. The land mapping units, resulting from the overlay of the selected theme layers, have unique land quality information, on which land suitability is based. Results showed that 55.5% of the study area is highly or moderately suitable for rice cultivation, whereas 34% of that area is unsuitable for rice cultivation due to soil and topographic conditions. The model was also validated with field studies. According to the statistical analysis, there was a …

Using Remote Sensing Data To Improve Rice Production In Kutigi, Niger State, Nigeria, Jibril Musa Phd, M B. Yunusa
Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria
This research work looked in the used of Remote Sensing to improve Agricultural production in Kutigi, Niger State. The aim of the study is to use remote sensing to improve rice farming activities in Kutigi, Niger State. It is very important to identify such methods to improve Agricultural production because experts are always interested in new researches and findings to better the standard of living in any environment. In view of this, Remotely-sensed data could be used or employed to elevate most of these agricultural problems in Kutigi through the following objectives: Using Landsat imagery to assess the present landuse …
Evaluation Of A Low-Cost Gps Receiver For Precision Agriculture Use In Adana Province Of Turkey, Muharrem Keski̇n, Sai̇t Muharrem Say, Serap Görücü Keski̇n
Evaluation Of A Low-Cost Gps Receiver For Precision Agriculture Use In Adana Province Of Turkey, Muharrem Keski̇n, Sai̇t Muharrem Say, Serap Görücü Keski̇n
Turkish Journal of Agriculture and Forestry
The most vital factor in the application of precision agriculture technology is the cost of the required high-technology equipment. The equipment cost is the major obstacle in adopting the precision agriculture. GPS receiver is one of the most essential tools with high initial costs in this technology. The aim of this study was to evaluate a low-cost GPS receiver in 3 different tests including static, dynamic circular area, and dynamic straight line tests. It was observed that the tested low-cost GPS receiver yielded a deviation of less than 1.50 m, 1.60 m, and 1.48 m in static, circular area, and …
Mapping Secondary Forest Succession With Geographic Information Systems: A Case Study From Bulanıkdere, Kırklareli, Turkey, Günay Çakir, Fati̇h Si̇vri̇kaya, Sali̇h Terzi̇oğlu, Emi̇n Zeki̇ Başkent, Turan Sönmez, Haci Ahmet Yolasiğmaz
Mapping Secondary Forest Succession With Geographic Information Systems: A Case Study From Bulanıkdere, Kırklareli, Turkey, Günay Çakir, Fati̇h Si̇vri̇kaya, Sali̇h Terzi̇oğlu, Emi̇n Zeki̇ Başkent, Turan Sönmez, Haci Ahmet Yolasiğmaz
Turkish Journal of Agriculture and Forestry
Developing forest management plans for sustaining the full range of forest values is a challenging task. One of the difficulties in this process is to set and achieve management objectives, and conservation targets. A sustainable forest management concept requires that a target forest structure (the composition and the configuration) be set before developing alternative management actions for the achievement of management objectives and the conservation targets. In this respect, developing and understanding vegetation succession play important roles in setting the target forest conditions. This study was conducted in the Bulanıkdere Forest planning unit (Kırklareli, Turkey) where the biodiversity-integrated multiple-use forest …
Use Of Remote Sensing And Geographic Information System Technologies For Developing Greenhouse Databases, Namik Kemal Sönmez, Mustafa Sari
Use Of Remote Sensing And Geographic Information System Technologies For Developing Greenhouse Databases, Namik Kemal Sönmez, Mustafa Sari
Turkish Journal of Agriculture and Forestry
This model study was conducted in Antalya region greenhouses for the determination and registration of agricultural resources as a part of adjustment efforts for the European Union (EU) Common Agricultural Policy (CAP). The aim was to create new database systems based on remote sensing (RS) and geographic information systems (GIS), rather than conventional land measurement techniques. For this purpose, glass and plastic greenhouses were determined by visual data analysis of satellite image, and databases were created for each greenhouse by GIS. These databases included area, coordinates and other characteristics of each greenhouse. These databases were prepared in a format that …

Turkish Journal of Agriculture and Forestry
Soil tensile strength (TS) and aggregate stability (AS) values can be used as indicators of soil structural quality. The objective of this study was to determine the influences of land use types, soil carbon and clay contents on soil structure. Soil samples were collected from 51 different locations from the Kumkale Basin in Çanakkale in April and July 2003. A global positioning system (GPS) was used to determine the coordinates of sampling points. TS, AS, soil organic carbon (SOC), and clay contents were determined. Results of soil analysis and coordinates of sampling points were transferred to the Arc View geographical …

Estimation Of The Effect Of Soil Salinity On Crop Yield Using Remote Sensing And Geographic Information System, Mehmet Ali̇ Çullu
Turkish Journal of Agriculture and Forestry
This study was conducted to estimate the effect of salinity on crop yield by employing a geographical information system (GIS) and remote sensing technologies. The saline soils of Arıcan village, located in the southeastern part of Harran Plain, were studied. Surface soil samples representing each soil series in the study area were collected and analyzed to generate an electrical conductivity (EC) map of the study area soils. Using ground truth information, satellite images were classified and land use classes were determined in the study area. The EC map, land use map, soil map and parcel map were combined and analyzed …
