SEPERATION OF IKONOS SENSOR’S ELECTRONIC NOISE FROM ATMOSPHERIC INDUCED EFFECTS

Atmospheric and Terrain Correction of Ikonos Imagery Using Atcor3

When ordering very high resolution (VHR) imagery of IKONOS or QuickBird a cloud coverage up to 20 % within the scenes has to be accepted. This indicates the high impact of atmospheric conditions to VHR imagery. Beside clouds the images are influenced by haze oftentimes. This haze could be removed using new atmospheric correction algorithms, which were not available for VHR data so far. Furtherm...

Extracting information from noise spectra of chemical sensors: single sensor electronic noses and tongues

Electronic noses and tongues can utilize noise data taken at the output of a chemical sensor. It is shown that even one single sensor may be suf®cient for realizing an electronic nose or tongue. # 2000 Elsevier Science B.V. All rights reserved.

Effects of Atmospheric Path on Airborne Multispectral Sensors

Experimental data were acquired for a study of the effects of variable atmospheric path on the spectral signals obtained by remote sensors in the optical region of the spectrum. Multichannel optical-mechanical scanners which provide calibrated apparent spectral radiance data were flown over agricultural test sites, and passes were made at several different altitudes between 2000 and 10,000 ft. ...

Sensors: From Biosensors to the Electronic Nose

Extracting Roads from Ikonos Images

Remote sensing has been used mostly to produce analyses on different aspects and phenomena concerning territory. The approach is not different from the one employed when analysing maps in the sense that analysis depends on the nature of data, maps and satellite images being two different sources of spatial data. Obviously, analysis based on cartographic data is different from the one based on s...
