With the development of satellite and remote sensing techniques, more and more image data from airborne/satellite sensors have become available. Multi-sensor image fusion seeks to combine information from different images to obtain more inferences than can be derived from a single sensor. In image-based application fields, image fusion has emerged as a promising research area since the end of t...

The Gigabit Satellite Network, a project jointly sponsored by ARPA and NASA, will provide longhaul STS-3 (155.54 Mb/s) and STS-12 (622.08 Mb/s) pointto-point and point-to-multipoint full-duplex services over NASA's Advanced Communications Technology Satellite (ACTS). Data multiplexing over the satellite will be accomplished using TDMA techniques coordinated with the switching and beam hopping f...

because of large-scale dry regions, salt marsh monitoring is necessary using of remote sensing data's. the aim of this study is to monitor salt kashan using of satellite data's processing. therefore, the satellite images of lissiii sensor were used. initially, the technique of color composite images envi4.8 software was used to clearly distinguish salt. then, principal component analy...

extended abstract introduction rainfall prediction at regional and global scales is mostly as principle component of hydro-meteorological studies in un-gauged regions. ground-based measurements of precipitation are available with high accuracy in synoptic stations. spatial distribution of operational stations is now as one of the biggest problems in the developing countries such as iran, which ...

There are a growing number of small satellites that are being launched and operated to accomplish novel science and technology missions. Scientists and mission operators are seeking to download large quantities of data from these small satellites, however they are resource-constrained and communicate to capacity-constrained ground networks. Motivated by the need for intelligent operational sche...

This paper presents preliminary research results on using semantic technologies to model Earth observation satellite data. The research goal is to enhance the data search functionalities that satellite data catalogues provide to researchers and practitioners. An ontology that captures characteristics of satellite data is introduced. How to utilize this ontology in assisting data search and how ...

The research used the satellite image (Landsat 7 ETM ) within the thermal infrared sixth band (TIR6) and geographic information system (GIS) to determine the air pollution and its relationship with the land cover (LC) and land use (LU) of Baghdad city. Concentration of total suspended particles (TSP), lead (Pb), carbon oxides (CO, CO2), and sulphur dioxide (SO2) were obtained from 22 ground mea...
