The airborne hyperspectral imaging data has operationally been used in environment, geology, agriculture and other fields. In this paper, airborne hyperspectral data in visible, SWIR, MIR and TIR spectral region acquired by the 128 band Operational Modular Imaging Spectrometer (OMIS) was attempt in urban object identification. Natural grassland/artificial grasslands, and different types of meta...

The potential for using airborne electromagnetic (AEM) methods for measuring water depth has been demonstrated from data acquired from several surveys over shallow coastal waters in Australia. These AEM surveys were undertaken using both fixed-wing time-domain and helicopter (time and frequency domain) commercial systems. Some survey data was also interpreted to delineate the bedrocksediment bo...

Imaging spectrometer data (also known as 'hyperspectral imagery' or HSI) are well established for detailed mineral mapping from airborne and satellite systems. Overhead data, however, have substantial additional potential when used together with ground-based measurements. An imaging spectrometer system was used to acquire airborne measurements and to image in-place outcrops (mine walls) and box...

The present investigation describes a method for sampling bidirectional reflectance information from multiangular airborne images. The method uses high resolution surface models in the determination of the location of the imaged point on the ground and in the image, and finally the orientation of the measured surface fragment. Two test sites were imaged with a wide range of azimuth angles at tw...

During the past few years lots of research has been carried out in the field of building extraction from airborne laser scanner data and airborne large-scale imagery. This data can be used to create highly detailed Digital Surface Models (DSMs) and eventually Digital City Models (DCMs). It seems that there exists also a potential in data acquired by high-resolution satellites and airborne multi...

Airborne magnetic systems for mapping unexploded ordnance (UXO) and other shallow metals have been developed at Oak Ridge National Laboratory (ORNL) over the past five years .We have recently completed testing of a time-domain electromagnetic (EM) system to supplement the magnetic system for UXO investigations. The test was conducted at the Badlands Bombing Range (BBR) in South Dakota in Septem...

[1] Digital elevation models (DEMs) of Bagley Ice Valley and Malaspina Glacier produced by (i) Intermap Technologies, Inc. (ITI) from airborne interferometric synthetic aperture radar (InSAR) data acquired 4–13 September 2000, (ii) the German Aerospace Center (DRL) from spaceborne InSAR data acquired by the Shuttle Radar Topography Mission (SRTM) 11–22 February 2000, and (iii) the US Geological...

Remote sensing applications like disaster or mass event monitoring need the acquired data and extracted information within a very short time span. Airborne sensors can acquire the data quickly and on-board processing combined with data downlink is the fastest possibility to achieve this requirement. For this purpose, a new low-cost airborne frame camera system has been developed at the German A...

Accurate spatial registration between multitemporal imagery is necessary if pixel-level changes are to be detected. Registration of multitemporal airborne frame imagery is complicated by image distortions resulting from wide view angles and variable terrain. A novel technique for acquiring and precisely registering multitemporal airborne frame imagery is presented. This technique, referred to a...
