the changes in time and location of surface temperature from a water body has an important effect on climate activities, marine biology, sea currents, salinity and other characteristics of the seas and lakes water. traditional measurement of temperature is costly and time consumer due to its dispersion and instability. in recent years the use of satellite technology and remote sensing sciences ...

Submetric satellite imagery (Pleiades, GeoEye) offers advantages for map update purposes, e.g. an interesting ground resolution, a good reactivity and the ability to capture wide areas. Experiments on the use of such stereoscopic images for 2D change detection among building objects of GIS topographic database are presented in this paper. Two approaches have been tested. The first one extracts ...

This study uses remote sensing techniques to study ahu (monumental ceremonial platforms) on the island of Rapa Nui (Easter Island). The first phase of the project used commercial satellite images to locate ahu and create a comprehensive GIS database to be corroborated during future ground survey. To supplement the satellite images, a second phase of the study evaluated kite photography a low-co...

The dynamic link among the Geographic Information System (GIS) ArcView, the dynamic statistical graphics (DSG) program XGobi, and the statistical computing environment XploRe has been successfully used to explore and analyze all kinds of spatially referenced data | from forest health data over precipitation data to precision agricultural data. In this paper, we will focus on the exploration of ...

In recent years, acquiring information of remote sensing data, especially satellite data has excessively increased and several methods are presented in order to improve the quality of remote sensing studies in earth sciences. It is possible to manage many projects and provide different types of thematic maps in a short period of time, and a low cost by utilizing satellite data and GIS method. R...

The demand in the Saudi markets for qualified environmental and landscape planners with Geographic Information System (GIS) & Remote Sensing knowledge, has led the Landscape Architecture Department, Faculty of Environmental Design, at King Abdulaziz University (KAAU) Jeddah to start a pilot project applying GIS and Remote Sensing techniques in a fourth year (third year department) landscape pla...

Natural disaster mitigation is a collective effort of; forecast, assessment, and encouraging the public participation in disaster mitigation. This study focused on the rarely addressed aspect, “the value of public awareness” in natural disaster mitigation. The methodology used satellite data and Geographic Information Systems (GIS) to produce semi-real-time “Media GIS” contents. When deliver th...

For merging Synthetic Aperture Radar (SAR) with georeferenced data, one usually uses processing software to orthorectify the SAR images in order to add them in a GIS. Nevertheless, this projection involves an important alteration of the information of SAR images and are often specific to some particular SAR sources. Moreover, the transformation of radarcoding data from a GIS into the radar geom...
