The LH Systems ADS40 airborne digital sensor is the first commercial digital CCD-line scanner for photogrammetric applications. CCD sensors allow true radiometric measurements in images. Multispectral...
Digital imagery from satellites or multispectral and hyperspectral scanners is well accepted. Tremendous challenges are inherent in the development of a digital sensor to acquire imagery suitable for ...
High performance photogrammetric cameras require high resolution geometric, spectral and radiometric calibration.Instruments to meet the stringent specifications exist at LH Systems and DLR. The under...
In this paper we present a laser calibration procedure that utilizes natural surfaces as calibration sites. The proposed calibration scheme includes the solution of the correspondence problem between ...
An increasing trend in the recurrence of natural disasters and associated impacts due to Floods, Glacier Lake out bursts, landslides and forest fire is reported over Hindu Kush Himalyan (HKH) region. ...
Natural resources dependence of mountain communities, rapid social and developmental changes, disaster proneness and climate change are conceived as the critical factors regulating sustainable Himalay...
India is prone to several natural disasters such as floods, droughts, cyclones, landslides and earthquakes on account of its geoclimatic conditions. But the most frequent and prominent disasters are f...
A Spatial Decision Support System (SDSS) provides support for decision makers and should not be viewed as replacing human intelligence with machines. Therefore it is reasonable that decision makers ar...
We describe several remote sensing research projects supported with small Unmanned Aerial Systems (sUAS) operated by the NGA Basic and Applied Research Office. These sUAS collections provide data supp...
Due to the low-cost and off-the-shelf availability of consumer grade cameras, multi-camera photogrammetric systems have become a popular means for 3D reconstruction. These systems can be used in a var...
In this paper, we present a novel linear approach for the initial recovery of the exterior orientation parameters (EOPs) of images. Similar to the conventional Structure from Motion (SfM) algorithm, t...
This paper presents the ongoing development of a small unmanned aerial mapping system (sUAMS) that in the future will track its trajectory and perform 3D mapping in near-real time. As both mapping and...
Among the main issues in the theory of geometric grids on spatial information systems, is the problem of finding the shortest path routing between two points. In this paper tried to using the graph th...
The currently existing mobile mapping systems equipped with active 3D sensors allow to acquire the environment with high sampling rates at high vehicle velocities. While providing an effective solutio...
This paper considers a statistical approach to define pseudo-moving (false) objects in video surveillance systems by constructing systems of hypothesis with the criteria based on statistical behaviora...
