Using unmanned aerial vehicle for remote sensing application

With the availability and development of multisensor, multitemporal, multiresolution, and multifrequency image data from operational Earth observation satellites, more limitations have also appeared in remote sensing image applications, and the most important one is the cost limit. To overcome the limitations, unmanned aerial vehicle (UAV) technology is developped for remote sensing application. It forms a rapidly developing area of research in remote sensing. This review paper describes and explains data acquisition and processing technologies for imageries from UAV, as well as summarizes the current application research with UAV. Then, it presents some problems and prospective for UAV development. It is our hope that this survey will provide guidelines for future applications of UAV and possible areas.
