GCOS (Global Climate Observing System) is a long-term program for monitoring the climate, detecting the changes, and assessing their impacts. Remote sensing techniques are being increasingly used for climate-related measurements. Imagery of the SEVIRI instrument on board of the European geostationary satellites Meteosat-8 and Meteosat-9 are often used for(More)
The geometric accuracy of the images acquired by the SEVIRI (Spinning Enhanced Visible and InfraRed Imager) instrument aboard the European geostationary satellites Meteosat-8 (formerly MSG-1) and Meteosat-9 (formerly MSG-2) has been investigated in this study. Level 1.5 image data of the High-Resolution Visible (HRV) band with 1-km Ground Sample Distance(More)
The geometric accuracy of the images acquired by the SEVIRI instrument aboard the European geostationary satellites MSG-1 and MSG-2 has been investigated in this study. Level 1.5 image data of the High-Resolution Visible (HRV) band with 1-km GSD and several multispectral bands with 3km GSD at sub-satellite point have been provided by the Swiss GCOS Office(More)
A new algorithm for automatic change detection is presented. It detects a pixel-change and DSM-change from two orthoimages and two DSMs, then it extracts the polygons in elevation-changed areas. Pixel-change is detected by using least squares fitting technique. This method can extract the visible changed areas between two orthoimages, while DSM-change is(More)
