policy making and planning for agricultural development and conditional improvement of rural and farmers requires accurate and real time information and statistics. in iran, accessing relevant agriculture statistics is mainly gained through expert knowledge and traditional methods. studies show that these have a high percent of error. this research has been aimed so to, by using new methods inc...

The growing use of Geographic Information Systems (GIS) has led to new research opportunities in the application of satellite imagery to urban analysis. The information content of such images is a function of the combined influence of the radiometric, spatial, and spectral resolution of the sensor. The different bands of satellite sensors are recorded synchronously so that their pixels may be p...

the preparation of vegetation cover maps by used the land inventory and a traditional method has a lot of cost and time. but today, remote sensing is one of the main sources of data collection and information production for study and monitoring land resources, and was efficient tools for providing quickly and timely data and information needs for program planning in the natural resource filed. ...

The rapid development and increasing availability of high-resolution satellite (HRS) images provides increased opportunities to monitor large scale land cover. However, inefficiency and excessive independence on expert knowledge limits the usage of HRS images on a large scale. As a knowledge organization and representation method, ontology can assist in improving the efficiency of automatic or ...

Summary Protected areas have numerous roles (such as biodiversity preservation, the development of scientific research and sustainable use natural resources), but they are under threat from political economic forces. The 837 000-ha Serra do Divisor National Park (SDNP) in south-western Brazilian Amazon combines conservation resources maintenance productive activities c . 400 resident families. ...

providing of landing use maps and detecting of land capacity are required to manage of natural resources and environment and planning of land use. on the other hand, it is necessary to detect of the human deriving forces affecting land use change. in this research, we selected seyed mohaleh and drasara villages in tonekabon city. first, were provided the land use maps in 1987 and 2008 by using ...

Landsat images from 1979, 1988, 1999, 2008, and 2013 were used to analyze the landscape area change of salt pans lying on the coast of Tianjin. While initially (1979–1988), the area of Tianjin’s salt pan increased, later (1988–2013) it declined dramatically. In the first phase (1979–1988) of the studied period the primary roll-in landscape of the salt pan wasbarren land with an area of 60.0 km2...

According to the Intergovernmental Panel on Climate Change Good Practice Guidance (IPCC GPG) (IPCC 2003), remote sensing methods are especially suitable for independent verifying the national Land Use, Land-Use Change, and Forestry (LULUCF) carbon pool estimates, especially the aboveground biomass. In the present study, we demonstrate the potential to integrate standwise inventory data, ASTER a...

background and objective: magnetic resonance imaging (mri) is the most sensitive technique to detect multiple sclerosis (ms) plaques in central nervous system. in some cases, the patients who were suspected to ms, whereas mri images are normal, but whether patients don’t have ms plaques or mri images are not enough optimized enough in order to show ms plaques? the aim of the current study is ev...
