Hyperspectral data contain a large volume of information. This abundance of data is hard to exploit due to high computational cost involved in processing this data. Dimensionality reduction deals with transforming high dimensional data in to lower dimensional space without losing significance of the High dimensional data. In this paper, a new methodology has been proposed that is based on exist...

This paper designs and develops a tool for detecting HABS from ENVI+IDL+ArcEngine. With a friendly and artistic interface offered by third party control, this tool provides a function of HABs monitoring in East China Sea via Remote Sensing Images inversion. Through rows of buttons on the menu bar, this tool allows calculating spectrum reflectance, browsing field work data, interpolating in situ...

Developing integrated farming systems is critical to reducing the environmental impact of animal production. Traditionally, this has been through integrating animal and feed or plant production. But that has become increasingly difficult as agricultural production has become regionally specialized leading to the spatial separation of animal and feed production. This spatial separation has led t...

The coastal region of Chabahar Gulf with 1113.7km2 area has been located in the southeast of Iran. In this research, satellite images of ETM+ (2004) were used in order to zoning of sedimentary environments in this Gulf. Methodology of this research was baesd on synthesis of supervised and unsupervised classifications in GIS and ENVI softwares. Based on studies and calculat...

with the wind permanent flow in the cities, obtaining the minimal pollution in the environment is accessible. different policies have been considered for optimization of cities such as attachment and or reduction of building parts like air-traps, ceiling forms and so on. due to population growth in cities and the increasing need for resettlement these people in the cities, inevitably, to the hi...

Morphological characteristics of cities significantly influence urban heat island intensities and thermal responses to waves. Form attributes such as density, compactness, vegetation cover are commonly used analyse the impact morphology on overheating processes. However, use abstract large-scale classifications hinders a full understanding trade-off between single buildings their immediate surr...

Documentation is fundamental to science. For virtual reality to be an e ective scienti c visualization tool, it must be recordable. This position statement outlines the bene ts of image-based recording of virtual environments and introduces the VR-VCR, a device for immersive playback of recorded virtual envi-
