Geographers use an assortment of tools and equipment to study the Earth. They study location, place, region, human-environmental interaction and movement. In order to study this they use globes, maps, satellites, GPS and GIS. The way geography is studied with a variety of tools, using different ways of scanning or portraying the Earth is really important, because thanks to these things, there are maps and globes. The
• Geotagging – Map overlays can be created by applying location coordinates to photographs and other kind of documents. • Surveying – Surveyors create maps and verify the boundaries of the property. • Map-making – Used by civilians and military cartographers. • Tectonics – Detect the direct false motion measurement in earthquakes. • Geofencing – Vehicle, person or pet can be detected by using GPS vehicle tracking system, person tracking systems, and pet tracking systems.
Fig 2: Branches of Geography. It studies the patterns and interactions between human activities and physical environment analyze the spatial pattern and relationships of environmental components of the globe in a regional context and studies the causes of regional patterns of such relationships. It takes into view both the spatial and temporal aspects of environmental components and their causes. The main concern of physical geography is biosphere which the layer of the life around the globe which supports the life of all biota (plants and animals) on the earth surface. The quality of biosphere is determined by the immediate physical environment which consequently is dependent on interactions between the endogentic
WAAS consists of a network of ground based reference stations to measure small variations in the GPS satellite’s signal. It has 2 master stations which arrange the correction messages properly and send them to the geostationary WAAS satellites. The satellites broadcast the correction messages back to the earth. . 8.
It is now referred to as a GNSS to reflect the fact that there is more than one satellite navigation system constellation available and that there are GNSS receivers that can use data from multi constellation. There are a number of techniques which the user can choose from when working with the multi GNSS namely being Real-time, post-processed, commercial or free services, Precise Point Processing (PPP) and PPP-Real Time Kinematic (RTK). This however has different levels of accuracy and time frame
1.1) Explain the principles of operation of the aircraft radar systems with appropriate block Diagrams and pictorial representation. (Assessment Criteria 4.1) Radio detection and ranging is an electromagnetic sensor used for detecting, tracking, locating and recognizing objects of various types at considerable distance. Radar operates by transmitting electromagnetic energy to objects commonly referred to as targets and observing the echoes of target which returns back. The target may be aircraft, spacecraft and astronomical bodies, or even like birds and rains. And finds the presence, location, and velocity of such objects and radar can find their size and shape as well.
For example, researchers have used a mathematical framework that benefits from the spatial relationships between places to estimate location from a sequence of images captured by multiple wearable cameras.15 The images recorded via WVLs can be also used to reliably recognize places. In addition, an image-sequence–matching technique can be used to recognize the locations of previously visited places. Activity Recognition Human-activity recognition is a key component for many applications such as indoor positioning, surveillance systems, and patient-monitoring systems. It is also important for various systems that involve interactions between people and electronic devices, such as socially enabled robots and human–computer interfaces. Wearable cameras can facilitate human-activity recognition in such scenarios.16 For example, researchers have developed a method that can recognize the user’s activity by analyzing the picture captured by a front-facing acamera embedded in eyeglasses.17
Soil remediation is a common term for various strategies that are used to purify contaminated soil. Soil contamination, also known as soil pollution, is brought by manmade chemicals or alteration in the natural soil. The soil contamination is caused by various factors such as industrial activities, improper waste disposal, acid rains, accidental oil spills, and agricultural chemicals. Pesticides, petroleum hydrocarbon, and heavy metals shavings are the most common chemicals causing soil pollution. Apart from this basic information, this post discusses various other pointers about soil remediation and the commonly used soil remediation equipment – regenerative blower.
valleys, hanging valleys, roche mountonnees, mushroom or gara, cliffs, bays, promonotaries etc.Relief features formed by the depositional work of the exogenetic forces are alluvial cones and alluvial fans, overflow lakes, natural levees and flood plains, deltas, morains, eskers, kames, drumlins, sand dunes, barkhans, beaches etc. All these features hold an important place as they give the description of the landforms formed on the surface of the earth. Diagram Space New concepts has come up in the field of Geomorphology 1. Over the years a better relationship has develop between geography, geomorphology and geology. Geomorphology is closely associated with geography and geology.
