Coastal zone of Sri Lanka is a key to sustainable development of the country. The erosion of country’s coastal zone has been identified as a long standing problem. Therefore, coastal sediment dynamics around the country has to be identified to develop an appropriate coastal zone management plan. Remote sensing and GIS techniques can be used for quantitative and qualitative analyses of coastal p...
With GIS technology for Web-enabled vector and meta data access becoming mature, the next quest is towards fast, flexible services on extremely large raster data assets. Currently 2-D images (satellite imagery, ortho photos) prevail, but at the horizon higher-dimensional objects appear, such as 3-D time satellite image time series and seismic data, and 4-D climate simulations. At the same time,...
Quantifying Urban Sprawl with Spatial Autocorrelation Techniques using Multi-Temporal Satellite Data
This study deals with the use of satellite TM multi-temporal data coupled with statistical analyses to quantitatively estimate urban expansion and soil consumption for small towns in southern Italy. The investigated area is close to Bari and was selected because highly representative for Italian urban areas. To cope with the fact that small changes have to be captured and extracted from TM mult...

This paper illustrates the use of GIS techniques and satellite data in order to analyze impact land change on local urban microclimate. Specifically, a case study is presented that concerns city Vienna. Thereby, satellite-based images were used classify Vienna into four zones toward computation surface temperatures two reference years. The classified maps then statistically projected future, re...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
One of the most important calamities that affect the arid and semi- arid regions and is taken into account as threatening factors for human- life and destroying the natural resources is desertification, so recognizing and forecasting this phenomenon is very important. Desertification is a complex phenomenon, which as environmental, socio-economical, and cultural impacts on natural resources. In...
Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...
