In this paper we introduced the principle of stereo imaging using linear arrays and its implementation in several imaging systems. A simulation study was conducted in which simulated IKONOS-I fore-, nadirand aft-looking images were produced using airborne AIMS images, IKONOS-I technical data, and a DEM. The attainable accuracy of ground points determined by the imagery is reported, considering ...

1. Abstract The SIMBA cruise in the austral winter season of 2007 conducted in situ measurements and used additional remote sensing resources to study the varied sea ice types at and inside the ice edge of western Antarctica in the Bellingshausen/Amundsen Seas. An element of the research aimed to ground truth satellite measurements by comparing with actual measurements performed on the sea ice....

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...

High resolution, optical satellite sensors are boosted to a new era in the last few years, because satellite stereo images at half meter or even 30cm resolution are available. Nowadays, high resolution satellite image data have been commonly used for Digital Surface Model (DSM) generation and 3D reconstruction. It is common that the Rational Polynomial Coefficients (RPCs) provided by the vendor...

the use of satellite data in an estimation of air temperature (ta) near the earth’s surface has turned into an effective way for a large area of high spatial and temporal resolution. throughout the present study, artificial neural network (ann) as well as m5 model tree were employed to estimate ta in khuzestan province (south west of iran), using satellite remotely sensed land surface temperatu...

In the present study, in order to calculate the movement of sand dunes in the period between 2001 and 2010, the ASTER (Advanced Space-borne Thermal Emission and Reflection Radiometer) images were used. The training samples were obtained from the field, and the images of the years 2001 and 2010 were classified using maximum likelihood algorithm and decision making tree. The study area was classi...

salinity is a phenomenon that does not satisfy the crop water requirement and leads reduction vegetation. to control of this phenomenon requires appropriate management and monitoring of spatial and temporal salinity variations from the past to the present in this study the spatial and temporal changes of soil salinity of irrigation and drainage network located in garmsar, iran, is investigated ...

the preparation of vegetation cover maps by used the land inventory and a traditional method has a lot of cost and time. but today, remote sensing is one of the main sources of data collection and information production for study and monitoring land resources, and was efficient tools for providing quickly and timely data and information needs for program planning in the natural resource filed. ...

â â  a great portion of precipitation in the south western iran falls in the snow formation. surface runoff produced from melting snow has an important role in the recharging ground water, surface and subsurface flows. rapid snowmelt can even cause flooding . since the snowmelt cannot be easily detected from optical satellite images, snow cover area (sca) is derived as an important hydrological...
