A casual Internet search can uncover much concern about the abruptness – and a potential for unnecessary “dodgesjust- in-case-the-azimuth direction…” – and the safety – of the climb / dive combination. Those and other capability restrictions are traceable to limited pre- GPS technology – highly dependent on transponders.

The key issue in the region is harmonization, which is not just a regional issue but rather a global matter. Within the region, different countries are at different stages of development, from Air Traffic Management (ATM) systems to procedures and airspace designs—some are quite advanced while others are just getting started.

Considering the transformational rate of growth in passenger traffic, airline fleet and the aircraft movements anticipated in the next few decades, the challenges that confront aviation are the need for matching airport/CNS-ATM infrastructure, airport/airspace capacity enhancement and technology up gradation.

The primary objective of ISAC is to build satellites to meet national requirement of the country in various application areas like satellite-based communication, navigation, national natural resources management, oceanography, meteorology, cartography and exploration of outer space and other planets, etc.

Two Radarsat-2 images acquired in fine quad-polarized mode were chosen for this study. The images were collected in leaf-on and leaf-off seasons. The experimental results demonstrated that the neighboring information provides valuable information for the classification of Polarimetric SAR data. The classification results showed that the proposed methodimproves classification accuracy significantly over the baseline methods.

Landslide occurrence is one of the natural disasters which causes great damages annually all over the world and that is the reason, prediction and monitoring of landslides is of great concern. Landslide susceptibility determination relies largely on information which is provided by the landslide inventory maps. Therefore, precise land displacement determination can be regarded as one of the preliminary steps towards a more reliable landslide prediction.

A comparison between the seismicity and active faulting density maps indiactes that a good spatial correlation can be observed between these two parameters. It probably means that active faults are the main seismogenic sources responsible for generating earthqukes in this region. The good consistency observed between the seismogenic zoning map presented in this research and the results of the previous works indicates that the spatial analysis techniques can reliably be used for seismic hazard regionalization and identifying seismogenic hazardous zones in seismically active regions.

Large scale seasonal atmospheric correction will be investigated using ERA-Interim meteorological model and GPS data. A twisted plane is also fitted to remove orbital errors. To investigate the long wavelength tectonic signal due to interseismic strain accumulation, a time series analysis of the selected Images has been done on a pixel basisin order to enhance signal to noise ratio affected by remaining atmospheric signal.
