Orthorectification is the process to convert imagery into map-accurate forms by removing sensor, satellite motion and terrain related geometric distortions from raw imagery and is one of the main pre-processing steps for application oriented evaluations. Although optical satellite data of high geometric resolution can be orthorectified to absolute geometric accuracies of about 5 m to several hu...
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...
Very high resolution optical space images are coming more and more into competition to classical aerial images making them more important for mapping projects. The orientation process of the dominating CCD-line scanner images taken from space is quite different from the orientation of perspective photos. Different image products like nearly original images and images projected to a plane with c...
We present a global ground-state potential energy surface for N4 suitable for treating high-energy vibrational-rotational energy transfer and collision-induced dissociation in N2-N2 collisions. To obtain the surface, complete active space second-order perturbation theory calculations were performed for the ground singlet state with an active space of 12 electrons in 12 orbitals and the maug-cc-...
ANDREA is a command-and-control service architecture for very large, distributed applications. Commandand-control systems are appealing because they apply directed action, a strategy familiar in the form of imperative programming. Tenability for this approach at very large scales, however, requires that controllers relax their system-state-knowledge. ANDREA supports this requirement with Site-S...
Smart aspects in development of a wheel-based robot which is capable to climb stairs autonomously are presented. Autonomy connotes the ability to climb stairs without any mechanical contact to environment except ground contact with wheels. A comparison of wheel-based to other known locomotion systems is given. Advantages of wheel-based systems are emphasized. The presented Stair Climber (SC) ro...
Due to the limited accuracy of exterior orientation parameters, ground control points (GCPs) are commonly required to correct the geometric biases of remotely-sensed (RS) images. This paper focuses on an automatic matching technique for the specific task of georeferencing RS images and presents a technical frame to match large RS images efficiently using the prior geometric information of the i...
