Continuous monitoring of naval activities of vast areas, hundreds of nautical miles away from shoreline, is one of todays most challenging problems. To enable total maritime awareness in these areas, the use of satellite-based sensors is an efficient and cost-effective way to perform this task. The KINGFISHER (Figure 1) is a maritime multi-layer intelligence system created for an in-depth analy...

This paper presents the results of the assessment of the developed techniques for line-based and combined point/line-based eight parameters projective equations. The developed equations were implemented in a general least squares adjustment technique where both lines and/or points can be used for the rectification of both aerial and satellite images. Several experiments were performed using the...

Past studies of the NOAA AVHRR/2 and GOES I-M imagery (e.g., Setvák et al., 1996) have shown that frozen tops of deep convective storms occasionally exhibit significant increase of cloud top reflectivity when observed in the 3.7 or 3.9 μm spectral bands. Similar storm top features have been documented in the NOAA-KLM AVHRR/3 1.6 μm spectral band (Setvák et al., 2003). Consequently, cross-compar...

The humid tropical region is always under partial or complete cloud covers. As a result, optical remote sensing images of this region always encounter the problem of cloud covers and associated shadows. In this paper, an operational system for producing cloud-free and cloud shadow-free image mosaics from cloudy optical satellite imagery is presented. The inputs are several cloudy images of the ...

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...

remotely sensed imagery is proving to be a useful tool to estimate water depths in coastalzones. bathymetric algorithms attempt to isolate water attenuation and hence depth from other factors byusing different combinations of spectral bands. in this research, images of absolute bathymetry using twodifferent but related methods in a region in the southern caspian sea coasts has been produced. th...
