The United States Marine Corps (USMC) currently operates a fleet of KC130 aerial refueling tanker aircraft. This paper uses queuing and simulation models to examine the USMC KC130 tanker requirement, contrasts the results and explores the budgetary implications of alternative fleet requirements. This analysis finds that queuing models don’t account for some of the complexities of aerial refueli...

A method for automated georeferencing of aerial images by means of existing orthoimages and height models is presented. Results with test material of the OEEPE are discussed. The automated process is supported by the use of various thresholds in order to eliminate blunders. Experiences with the settings of these thresholds are discussed. After automatic elimination of some blunders in the autom...

— A correct radiometric normalization between both images is fundamental for change detection. MAD method and its IR-MAD extension in an implementation on multisprectral aerial images is described in this paper.

Feel lonely? What about reading books? Book is one of the greatest friends to accompany while in your lonely time. When you have no friends and activities somewhere and sometimes, reading book can be a great choice. This is not only for spending the time, it will increase the knowledge. Of course the b=benefits to take will relate to what kind of book that you are reading. And now, we will conc...

Built-up areas have been expanding throughout the world. Monitoring and prediction of the build-up is not only important for the economic development but also acts as sentinels of environmental decline important for ecologically sustainable development of a region. The aim of this paper is to model the growth of built-up and residential-commercial dwellings over the recent past and thus predict...

This paper studies trajectory control of aerial vehicles equipped with robotic manipulators. The proposed approach employs free-flying multi-body dynamics modeling and backstepping control to develop stabilizing control laws for a class of underactuated aerial systems. Two control methods are developed: coordinate-based and coordinate-free which are both generally applicable to aerial manipulat...

The spread of exotic conifers from commercial plantation forests has significant economic and ecological implications. Accurate methods for invasive conifer detection are required to enable monitoring and guide control. In this research, we combined spectral information from aerial imagery with data from airborne laser scanning (ALS) to develop methods to identify invasive conifers using remote...

flat, a high accuracy of the DTM is required for tasks such as hydrographic modelling. Airborne lidar (light detection and ranging) has become a standard method for DTM generation in coastal zones. The lidar technique has two main advantages compared to traditional aerial photogrammetry: Firstly, the active laser technique works independently from illumination from the sun, which allows mapping...

We are pursuing the detection of runways in aerial images as part of a project to automatically map complex cultural areas such as a major commercial airport complex. This task is much more difficult that appears at first. _ We use a hypothesize and test paradigm. Hypotheses are formed by looking for instances of long rectangular shapes, possibly interrupted by other long rectangles. We use run...
