The information contents of high resolution space images, usable for mapping, are not only depending upon the image resolution that means in case of digital data, depending upon the pixel size in the object space. Important is also the contrast, the spectral range, radiometric resolution and colour beside the atmospheric condition and the object contrast. From the area of Zonguldak, Turkey diff...

Various regions in Europe have suffered from severe flooding over the last decennium. Earth observation techniques can contribute toward more accurate flood hazard modelling and they can be used to assess damage to residential properties, infrastructure and agricultural crops. For this study, detailed land cover maps were created by using IKONOS-2 high spatial resolution satellite imagery. The ...

High-resolution satellite images having a footprint smaller than 5 m are becoming increasingly available. A large number of the high resolution satellite sensors acquire imagery in a pushbroom mode with CCD linear array technology. The need for accurate 3D object reconstruction requires a sophisticated camera model, being able to deal with such sensor geometry. The software package SAT-PP (Sate...

Bu çalışmada, pankromatik bandın çok bantlı uydu görüntülerinin piksel tabanlı sınıflandırma doğruluğuna etkisi deneysel olarak araştırılmıştır. Çok yüksek uzamsal çözünürlüklü multispektral görüntüleri bantlar yanında daha çözünürlükte bir bant içermektedir. nedenle aşamasında çeşitli seçenekler oluşmaktadır.Örneğin, yapıldığında bu kullanılmalı mı? Kullanılacaksa nasıl kullanılmalı? Sınıfland...

There is no research which specifically investigates the influence of the Digital Elevation Model (DEM) on topographic correction of satellite images. Such an investigation is necessary in view of the very high resolution (VHR) of recent sensors such as Ikonos and QuickBird and the low availability of accurate height information for the derivation of slope and aspect values. A comparative study...

I<span>Image-fusion provide users with detailed information about the urban and rural environment, which is useful for applications such as planning management when higher spatial resolution images are not available. There different image fusion methods. This paper implements, evaluates, compares six satellite image-fusion methods, namely wavelet 2D-M transform, gram schmidt, high-frequen...
