abstract the amount of needed fertilizer in agricultural soils depends to the type of crop. absence of enough fertilizer may cause in tensions in plants and consequently result in decrease in amount of product. according to the agricultural literature, soils containing total nitrogen amounts (n %) between 0.1-0.15 percent are considered as soils containing normal amounts of nitrogen. the values...

In the last decade, with the advance of technology, and the development of more sophisticated remote sensing sensors systems, the use of satellite imagery and remote sensing has opened the fields of exploration and application. Among these new fields is transportation. As this imagery data becomes more readily available, transportation organizations will have to learn to exploit these useful sy...

The learning environment makes appropriate use of a variety of media. Various learning styles are best engaged by using a variety of media to achieve learning outcomes. Selection of media may also depend on nature of content, learning goals, access to technology, and the local learning environment. This present paper proposes a teaching methodology of Remote Sensing and Image Processing, based ...

Although nano/microsatellites have great potential as remote sensing platforms, the spatial and spectral resolutions of an optical payload instrument are limited. In this study, a high spatial resolution multispectral sensor, the High-Precision Telescope (HPT), was developed for the RISING-2 microsatellite. The HPT has four image sensors: three in the visible region of the spectrum used for the...

North Hebei province lies in the ecotone from agriculture to animal husbandry and forest and is eco-fragile transitional region. Serous land degradation, especially grassland degradation occurs in this area, because of overgrazing and over-reclamation. There are also many disasters, such as drought, dust storm, forest fire, and so on. This area has characteristics of ecological degradation and ...

There are a great deal of obvious issues about effects of scale and scaling conversion that need to be solved for agricultural condition monitoring using remote sensing. In this paper, a serial of researches about them were performed so as to service practical requirements of agricultural condition remote sensing monitoring, especially in the dynamic monitoring of crops growth using remote sens...

With the rapid development of remote sensing technology, the quantity and variety of remote sensing images are growing so quickly that proactive and personalized access to data has become an inevitable trend. One of the active approaches is remote sensing image recommendation, which can offer related image products to users according to their preference. Although multiple studies on remote sens...

Spatiotemporal data, especially remote sensing data, are widely used in ecological, geographical, agriculture, and military research and applications. With the development of remote sensing technology, more and more remote sensing data are accumulated and stored in the cloud. An effective way for cloud users to access and analyse these massive spatiotemporal data in the web clients becomes an u...

S PACEBORNE and airborne remote sensors have important applications in environmental monitoring, resource management, disaster response, and homeland security. Remote sensors with different modalities (e.g., multispectral, hyperspectral, optical, infrared, and radar sensors) are now often used together to achieve the optimal outcomes in information mining and scene understanding. Pattern recogn...
