What is Geography?
Geography is the study of earth’s surface and the processes that shape it. It is the connection between places.
Who are Geographers? Geographers are scientists who study the relationship between people and their environments.
Two main branches of geography
• Physical geography
Study of the physical features and changes on the earth’s surface.

• Cultural geography
Study of humans and their ideas and the impact of human ideas and actions on the earth.

MODERN TECHNIQUES IN GEOGRAPHY

1. Geographic Information System (GIS)

The area can be expressed in a wide range of routes, for example, latitude and longitude, address, or ZIP code. Various sorts of data can be looked into utilizing GIS. The framework can include information about individuals, for example, population, salary, or education level. It can incorporate data about the area, for example, the area of streams, various types of vegetation, and various types of soil. It can include data about the destinations of factories, farms, and schools, or storm channels, streets, and electric power cables.
Data and GIS
Information in a wide range of structures can be entered into GIS. Information that are now in map form can be included into GIS. This includes such data as the area of waterways and streets, slopes and valleys. Digital or electronic information can likewise be entered into GIS.
An example of this sort of data will be information gathered by satellites that show land utilize, the area of farms, towns, or forests. GIS can also include information in table form. For example, populace data. GIS innovation allows all these distinctive sorts of data, regardless of their source or unique format, to be overlaid on top of each other on a single

• Laser and radar altimeters on satellites have provided a wide range of data. By measuring the bulges of water caused by gravity, they map features on the seafloor to a resolution of a mile or so. By measuring the height and wavelength of ocean waves, the altimeters measure wind speeds and direction, and surface ocean currents and directions.
• Ultrasound (acoustic) and radar tide gauges measure sea level, tides and wave direction in coastal and offshore tide gauges.
• LIDAR is used to detect and measure the concentration of various chemicals in the atmosphere, while airborne LIDAR can be used to measure heights of objects and features on the ground more accurately than with radar technology. Vegetation remote sensing is a principal application of LIDAR.
• Within the scope of the combat against desertification, remote sensing allows to follow-up and monitor risk areas in the long term, to determine desertification factors, to support decision-makers in defining relevant measures of environmental management, and to assess their

Economies of Scale

...more profit than competitor's regions. Since economies of scale lay it main focus on having an efficient production this shapes the economic development of regions. This paper is about economies of scale it describes how economies of scale shape the economic development of regions through description of different types of economies of scale and examples of countries and regions around the global (Stamp, 2009). Structure Definition Economies of scale is the cost advantages by enterprises due to size, input, or scale of operation, with cost per unit decreasing with increasing scale as fixed costs are spread out more to units of output. Economies of scale are known to improve with growing firms, therefore; it can be said that the economies of scale are directly proportional to the size of the firm (Stamp, 2009). From a simple firm which produces exercise books, the firm uses £200 to produce 10 exercise books meaning the average cost is £20 if the firm produces 40 exercise books the average cost is £12.The difference here is brought by the fact that the fixed cost used by the firm to produce exercise books is spread out more to units of output (Thatcher, 2009). Types of economies of scale Economies of scale can either be or external scale economies or internal scale economies. In the external scale economies, it is where benefits of positive externalities are enjoyed by firms as an outcome of the development (Pratten,...

Global Political Economy

...GRADUATE DIPLOMA IN INTERNATIONAL RELATIONS AND DIPLOMACY STUDENT GUIDELINE NOTES GLOBAL POLITICAL ECONOMY MODULE Paste the notes here… Political economy originally was the term for studying production, buying and selling, and their relations with law, custom, and government. Political economy originated in moral philosophy (e.g. Adam Smith was Professor of Moral Philosophy at the University of Glasgow), it developed in the 18th century as the study of the economies of states — polities, hence political economy. In late nineteenth century, the term "political economy" was generally replaced by the term economics, used by those seeking to place the study of economy upon mathematical and axiomatic bases, rather than the structural relationships of production and consumption (cf. marginalism, Alfred Marshall). History of the term Originally, political economy meant the study of the conditions under which production was organized in the nation-states. The phrase économie politique (translated in English as political economy) first appeared in France in 1615 with the well known book by Antoyne de Montchrétien: Traicté de l’oeconomie politique. French physiocrats, Adam Smith, David Ricardo and Karl Marx were some of the exponents of political economy. In 1805, Thomas Malthus became England's first professor of political economy, at the East India Company College, Haileybury, Hertfordshire. The world's first professorship in political economy was......

Shake and Erupt

...for my mixed ability year nine class offers a plethora of attributes that both incorporates sound core Geographic knowledge and divers teaching formats that can present a degree of awe and wonder into the minds of young people. Planning and teaching such a topic at a time when the Geography National Curriculum is being reviewed by the new coalition Government, seems to provide somewhat of a blank canvass as to what pedagogical approaches might be the most appropriate to adopt. Whatever the NC will look like, we are led to believe that there will be a re-focus on the ‘core’ knowledge in subjects like Geography. This is not to say a return to didactic teaching where teachers are merely transmitters of information, or indeed to adopt a textbook pedagogy which is reminiscent of the late 1970s and 1980s. The Geography Curriculum Consultation Full Report makes it clear “That a line-by-line, detailed list of geography’s contents is not the best way to draw a positive response from teachers . . . though there is strong support for the national curriculum achieving greater clarity over the core and essential knowledge contents of geography.” (Geographical Association, 2011, p.2 – cited in Debates in Geography). Having observed lessons in my school for several weeks now, I agree with this emphasis on teaching ‘core’ knowledge contents as I feel as if the emphasis in the classroom is more centred around designing creative activities which attempt to gain ‘buy-in’ from the......

Physical Geo

...Physical Geography Chapter 1: The Discipline of Geography Principles of Geography Geography is the study of the distributions and interrelationships of earth phenomena. Geography is different from other disciplines in that it doesn't have a particular "thing" it studies. Botanists study plants, while geologists are interested in rocks. Geography is defined by its approach or methodology. Geographers describe their discipline as a spatial science. By "space" we aren't talking about celestial space. Geographers are concerned with answering questions about how and why phenomena vary across the surface of the Earth. For instance, geographers investigate patterns of vegetation as they relate to distributions of climate, soils, and topography. Geographers recognize the dynamic nature of Earth's physical systems. The physical geography of Earth changes in response to variations in weather and climate, the shifting of continents, and and the sculpting of coastlines by wave action. By recognizing the Earth system is dynamic, geographers take time into consideration when looking at the spatial patterns of Earth phenomena. Therefore, geographers are playing important roles in understanding the effects of climate change on earth systems. The role of geographers in assessing patterns of environmental change is a theme that reoccurs throughout this book. Figure 1.1 Folded Appalachian Mountains Linear folds of the Appalachian Mountains can be easily seen in this satellite image. (Source:......

Although my family moved to the US before I entered high school, I have always kept my eyes turned north, especially in recent years as I began to read journal articles about research conducted on John Evans Glacier, located about 80° N latitude. Graduating next semester with a B.S. in computer science and engineering and a minor in geographic information systems, I am interested in attending the University of Alberta for graduate study. Geographic information systems (GIS) is a field especially suited to investigating spatial patterns, modeling diverse scenarios, and overlaying spatial data. This semester, in my advanced GIS course, Spatial Data Structures and Algorithms, I am part of a team developing a temporal database and program for tracing historical trading data. My computer science skills have also been put to use in two summer internship projects, where I acquired proficiency with using LIDAR (light detection and ranging) technology, now favored by NASA in its current 10-year study of Greenland and changes in the ice cap extent.

Lecture

...THE INCREASING RETURNS REVOLUTION IN TRADE AND GEOGRAPHY Prize Lecture, December 8, 2008 by Paul Krugman Princeton University, Woodrow Wilson School, Princeton, NJ 08544-1013, USA. Thirty years have passed since a small group of theorists began applying concepts and tools from industrial organization to the analysis of international trade. The new models of trade that emerged from that work didn’t supplant traditional trade theory so much as supplement it, creating an integrated view that made sense of aspects of world trade that had previously posed major puzzles. The “new trade theory” – an unfortunate phrase, now quite often referred to as “the old new trade theory” – also helped build a bridge between the analysis of trade between countries and the location of production within countries. In this paper I will try to retrace the steps and, perhaps even more important, the state of mind that made this intellectual transformation possible. At the end I’ll also ask about the relevance of those once-revolutionary insights in a world economy that, as I’ll explain, is arguably more classical now than it was when the revolution in trade theory began. 1. TRADE PUZZLES In my first year as an assistant professor, I remember telling colleagues that I was working on international trade theory – and being asked why on earth I would want to do that. “Trade is such a monolithic field,” one told me. “It’s a finished structure, with nothing interesting left to do.” Yet even before the......

The Global Crane market is undergoing a radical change due to growth of the emerging economies, infrastructure industry and drive towards greater energy efficiency. According to TechNavio’s analysts forecast the Global Crane market is expected to grow at a CAGR of 7.29 % over the period 2013-2018[7]. Fig1- Regional differences, Source - http://www.khl.com/servlet/file/CHRIS%20SLEIGHT.pdf?ITEM_ENT_ID=81256 The Indian industrial crane market amounts to approx. Rs2000 to 2200 crore per annum. Majorly 70% demand comes from the private sector and 30% from the government owned companies (Saibal ray, Yigal Gerchak & Elizabeth M. Jewkes, 2002) India has few factors which would ensure the steady growth of this segment in the next few years. The increase in domestic spending on infrastructure as stated in the Budget 2014-15, increased investment from foreign multinationals would prove to be a key factor in the growth of the construction industry as a whole. ElectroMech is the largest EOT cranes manufacturer in India with Pune being the base. It commands the highest market share and is recording 50% average annual growth.
