Recent studies showed that remote sensing (RS) is an effective, efficient and reliable technique used in almost all the areas of earth sciences. Remote sensing as being a technique started with aerial photographs and then developed employing the multi-spectral satellite images. Nowadays, it benefits from hyper-spectral, RADAR and LIDAR data as well. This potential has widen its applicability in...

Many studies on remote sensing monitoring of plant diseases have been conducted. Remote sensing (RS) has played an important role in monitoring some kinds of plant diseases and making decisions for the management of the diseases. Progress on remote sensing monitoring of wheat stripe rust in China was summarized from four aspects including remote sensing monitoring stripe rust of single wheat le...

Bibliometric analysis based on the Science Citation Index Expanded published by Thomson Scientific was carried out to identify the research status and future trends of remote sensing (RS) during 2010–2015. The analysis revealed the institutional, national, spatio-temporal, and categorical patterns in remote sensing research both from the WP (whole publications) viewpoint and the HCP (highly-cit...

This chapter presents an extensive and critical review on the use of kernel methods and in particular of support vector machines (SVMs) in the classification of remote-sensing (RS) data. The chapter recalls the mathematical formulation and the main theoretical concepts related to SVMs, and discusses the motivations at the basis of the use of SVMs in remote sensing. A review on the main applicat...

The use of new methods, remote sensing (RS) and geographical information system (GIS) in zoning the water erosion in a particular geographical area (Tang-e-Bostanak catchment area) constitute the main subjects of this study. The production, combination, and composition of effective information layers in identifying these zones have been noted, highlighting the capacity of GIS and RS. In this st...

Remote sensing data is a collection of images and interpretation of information about an object, area, or event without any physical contact with it. Aircraft and satellites are common remote sensing platforms for earth and its natural sources. Remote sensing’s ability to identify and monitor land surfaces and environmental conditions expanded over years with remote sensed data being essential ...

A novel remote sensing (RS) laboratory based on the hardware/software (HW/SW) co-design paradigm for the image enhancement/reconstruction problems pursuing the real time implementation is presented in this study. The application of the developed approach consider the typical single-look synthetic aperture radar (SAR) imaging systems operating in real-world RS scenarios with uncertainties attrib...

In recent years remote sensing (RS), geographic information systems (GIS) and global positioning systems (GPS), have been three main technologies for spatial information acquisition, spatial data storage management, spatial data updating, spatial analysis and applications. However, the integration of the three technologies is an important issue and a big challenge to the geo-information communi...
