In land use planning, mapping the present land use / land cover situation is a necessary tool for determining the current condition and for identifying land use trends. In this study, in order to provide a land use/ land cover map for Ilam watershed, the IRS-1C image data from 25th April 2006 were used. Initial qualitative evaluation on data showed no significant radiometric error. Ortho-rectif...

Recently, studies on the construction of 3D terrain modeling and location accuracy evaluation using UAV have been conducted, but application to coastal areas lacking image matching points has not made in detail yet. In topography survey UAV, ortho-images DSM (Digital Surface Model) data were constructed through imaging ground control point (GCP) surveying ground. case ortho-images, VRS was used...

The HRS (high resolution stereo) is an autonomous imaging system on SPOT 5. It has been designed especially for the generation of digital elevation models (DEMs). The combination of a forward and a backward view do allow a stereoscopic imaging with a height to base relation of 1.2 and just 90 seconds time interval. Some images, which are usually not accessible and used only by SPOT Image for th...

Accurate registration of airborne images is challenging because complex local geometric distortions are often involved in image acquisition. In this paper, we propose a solution to this registration problem in two parts. First, we present an area-based method to extract sufficient numbers of well-located control points, and second, we use the extracted control points with local transformation m...

Automatic registration is one of the key technologies for remote sensing image processing.Considering the influence of cloud points, the phenomenon of uneven distributed control points and other problems in the process of registration for the widely used AVHRR remote sensing images, an automatic registration method for AVHRR remote sensing images is proposed. In this method, the cloud points ar...

As the resolution of satellite images is improving, the applications of satellite images become widespread. Orthorectification is an indispensable step in the processing for satellite images. EROS A is a high resolution imaging satellite. Its linear array pushbroom imager is with 1.8meter resolution on ground. The satellite is sun-synchronous and sampling with asynchronous mode. The main purpos...
