The European Space Agency satellite Sentinel-2 provides multispectral images with pixel sizes down to 10 m. This high resolution allows for ship detection and recognition by determining a number of important ship parameters. We are able to show how a ship position, its heading, length and breadth can be determined down to a subpixel resolution. If the ship is moving, its velocity can also be de...

With the advancement of remote sensing sensor technologies, images of the earth’s surface have been collected at different spatial resolutions, in different spectral wavelengths (panchromatic, multispectral, hyperspectral), and with mono or stereoscopic views. The advancement of the technologies for geospatial information acquisition and extraction has allowed the generation of digital elevatio...

When performing post-classification comparison using images of different sensors, change detection is still possible even if images have different resolutions. However, in this case, change pixels are detected in the pixel size of coarser resolution image. This problem can be solved using higher resolution aerial photographs or panchromatic images if available. In multi sensor image fusion, ima...

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 at MeteoSwiss. A set of fully automated...

For the years 1997 to 2000 it is expected that a number of new satellites will be launched into orbit by private companies which are specified to deliver panchromatic imagery of the earth surface with a spatial resolution as fine as 1m. In contrast to the panchromatic band, the spectrally resolved bands will have a four times coarser ground resolution. Therefore, image fusion algorithms will be...

ABSTRACT: Due to the development of spatial resolution, spectral resolution and multi-image tasking of high-resolution satellite images, the generation of digital surface model (DSM) from high-resolution satellite images becomes an important and practical application. Nowadays, different image matching approaches such as global matching and semi-global matching has been developed to obtain dens...

the study on water level fluctuation in the urmia lake has become of a great importance in recent years. this is due to the importance of the position of this lake as a natural heritage at an international level. the water level decrease at the urmia lake during the recent years has made it necessary to address the matter more than before. investigation and assessment of changes in the lake is ...
