Multiple satellite methods exist for remote sensing of rip currents each with their own benefits and drawbacks. Photobathymetry, currents interaction using with Synthetic Aperture Radars (SARs), wave refraction, and wave kinematics bathymetry (WKB) are current technologies that are used most often due to the current satellite knowledge. Each of these techniques can be applied using low orbit satellites that are already currently orbiting Earth. All techniques aside from WKB have been tested as satellites
Satellite technology has advanced dramatically since the launching of the first artificial satellite, Sputnik, in 1957. There are hundreds of satellites orbiting Earth right now, launched and funded by many different nations (the US included). They are used for things like GPS or cellular communication, but also for measuring different aspects of our planet. Satellites’ ability to see into different sections of the light spectrum enable them to collect data better and more efficiently than ever before
agencies that have the ability to perform Signals Intelligence, electronic reconnaissance and most of all signals intelligence from all available sources inducive to the environment. The United States Army uses the Joint Surveillance Target Attack Radar System (Joint STARS) as its main entity for signals collection. The Joint STARS platform was designed to provide a highly effective, real-time, collection tool to the ground task force commanders during battlefield engagements, but for the past ten
Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene
Like much of today’s technology, Unmanned Aerial Vehicles attribute their creation to the military. The idea of using unmanned aircraft has long been a dream for the military -- scouting planes without any casualties to report should something go wrong, air strikes with only time and money to lose, and the ability to wage war without losing a single life. Well the third one may perhaps not be realistic – as Afghanistan has shown, lack of ground troops leaves certain entities unchecked.1 However
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 can be expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this
The year was 1946. World War 2 had ended only months before, and already the stage was set for another global conflict. The United States and the Soviet Union, formerly allies in the war against Hitler's Third Reich, were now engaged in a standoff over what system of beliefs would prevail over the slowly recovering nations of Europe. The Soviet Union wasted no time in forming an Eastern Bloc, a group of satellite nations controlled by puppet governments, whose primary purpose was to provide a buffer
This paper will give a brief definition of the term Artificial Intelligence (AI). It will take an in-depth look at the origins and purpose of this exciting field in computer science. In particular, this paper will discuss a few of the many subcategories of research, applications and current technological obstacles that scientist face when developing AI. In addition, the author will look at AI’s various military specific applications for the purpose of training, target acquisition and command and
QUESTION What is the role of GIS and Remote Sensing in 1. Environmental Impact Assessment 2. Substance Flow Analysis 3. Carbon Foot printing 4. Health Impact Assessment 5. Social Impact Assessment Introduction Geospatial techniques such as Geographic Information Systems (GIS) and remote sensing play a pivotal role in Environmental Impact Assessments (EIAs) and their various components such as ecological, social and hydrological impact assessment. These tools have proved so useful that they
tropical rainforests been [6]. Satellite imagery provides an efficient means to retrieve information on the status and extent of forest resource and changes thereof. The large are coverage and high spatial resolution of newly launched optical and radar satellite systems offer new opportunities to remotely estimate and access land cover information on a wall-to-wall basis. At the same time the high temporal resolution and capacity
