Geographic Information Systems Geographic information systems (GIS) technology can be used for scientific investigations, resource management, and development planning. For example, a GIS might allow emergency planners to easily calculate emergency response times and effected areas of the ocean during an oil spill based on the spills location. You may ask, what is GIS? In the strictest sense, a GIS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information, i.e. data identified according to their locations. Practitioners also regard the total GIS as including operating personnel and the data that go into the system. A geographic information system (GIS) works in a series of steps, First there is the relating information from different sources. If you could relate information about oil spill location to the oceans surface currents, you might be able to tell where to start clean up based on how long the oil has been in the ocean. A GIS, which can use information from many different sources, in many different forms can help with such analyses. The primary requirement for the source data is that the locations for the variables are known. Location may be annotated by x, y, and z coordinates of longitude, latitude, and elevation and any variable that can be located spatially can be fed into a GIS. Several computer databases that can be directly entered into a GIS are being produced by Federal agencies and private firms. Different kinds of data in map form can be entered into a GIS. A GIS can also convert existing digital information, which may not yet be in map form into forms it can recognize and use. For example, digital satellite images can be analyzed to produce a map like layer of digital information about marine life productivity. Likewise, sea-grass data can be converted to map-like form, serving as layers of thematic information in a GIS. Next Step for Geographic information systems (GIS) would be to Capture the data If the data to be used is not already in digital form, that is, in a form the computer can recognize, various techniques can capture the information. Maps can be digitized, or hand-traced with at computer mouse, to collect the coordinates of features. Electronic scanning devices will also convert map lines and points to digits. A GIS can be used to emphasize the spatial relationships among the objects being mapped.
1. Was Terminiello's right to free speech, which is protected under the Federal Constitution, violated, as applied in this case?
Freedom of speech has been a controversial issue throughout the world. Our ability to say whatever we want is very important to us as individuals and communities. Although freedom of speech and expression may sometimes be offensive to other people, it is still everyone’s right to express his/her opinion under the American constitution which states that “congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or the press”. Although this amendment gave people the right express thier opinions, it still rests in one’s own hands as how far they will go to exercise that right of freedom of speech.
The dawn of a new engineering technique called geoengineering aims to save the Earth via large-scale manipulation of the environment to counteract global warming. “The Geoengineering Gambit” by Kevin Bullis, is an article about some of the ways geoengineering could solve the climate crisis and the problems that could be created by those solutions. Bullis gained knowledge of geoengineering and the climate problem from his work as energy editor for the journal Technology Review. Bullis' job as an editor builds for him a strong base of believability in the field, and demonstrates the basis for his credibility while building his ethos. The proposed geoengineering solutions are in relation to the current climate problems. Bullis’ purpose was to bring attention to the current geoengineering proposed solutions. Bullis talks about the current solutions that geoengineering offers but also the perceived problems as well. Bullis also brings up the ethical problems that can arise from these solutions. For example, problems nations would have with another nation launching things into the atmosphere is one of the many problems Bullis finds cause to study. Bullis also brings up his feelings on geoengineering and how it would be better if mankind were able to lessen the impact on our environment instead of applying temporary or artificial fixes. Bullis intentionally aimed this article at everyone given the worldwide impact on people that some claim through geoengineering. Bullis unintentionally aimed the article at the US Government and other leaders from influential nations. The tone of the article is really saying that geoengineering could possibly help but more tests and results are necessary before drawing important conclusions. ...

There are many geographic features around the world. These geographic features can influence the development of a region or civilization and promote or limit interaction with other civilizations. Geographic is the study of the various features of the earth. Two geographic features that have been important are the Nile River and the Mediterranean Sea.
As applications of geospatial technologies continuously break the disciplinary barrier, the need for books on these technologies to reach diverse audiences is greater than ever. The challenge, however, is to write a book on this complicated subject that incorporates the knowledge of multiple disciplines and makes it valuable for those who may or may not have diverse educational backgrounds, but require using these technologies. Most books on geospatial technologies target a specific audience. Contrary to this, Geographical Information Science tries to target three different audiences (users, students, and engineers) by using formats and languages comfortable to them. While this effort is laudable, maintaining the balance and attractiveness to all the three audiences is challenging. The author, Narayan Panigrahi, has accomplished this balancing act but with mixed outcomes. His computer science background is clearly seen in the structure and contents of the chapters.
Geographers plan new communities, decide where new highways should be placed, and establish evacuation plans. Computerized mapping and data analysis is known as Geographic Information Systems (GIS), a new frontier in geography. Spatial data is gathered on a variety of subjects and input onto a computer. GIS users can create an infinite number of maps by requesting portions of the data to plot.
Now days, companies are searching for new ways of gathering data so that they can get useful data in order to make well informed decisions regarding the market they are operating in. Google analytics is considered one of the best tools offers extensive amount of data to business owners for free. However, the success of business is highly depended on how well they can arrange data and customize their collected data corresponded to their business priorities. Google analytics provides beneficial information for companies regardless of their extent of operation. Google Analytics (Location data)
The six concepts of geography are location, region, spatial pattern, spatial interaction, human/ environmental interaction, and culture. The location is everything; it is the starting point in geography. The region is the area of the land with consistent recognizable features, it has variations in its physical features. There are mountains, hills, valleys, plains, plateaus, oceans, lakes, deserts and wilderness, variations occur in its social and cultural features too. The spatial pattern is when a pattern is found in places that are far apart. Spatial interaction is when geographers believe one event can lead to a change in another location that is far away. Managing change is a key aspect of geography, geographers learn from past changes and predict and future ones. Human/ environmental interaction is the impact humans have on the environment. Interaction is closely linked to change. Again, in both physical and human aspects of the subject, geographers want to find out how things are linked together and how one aspect affects another. Lastly culture has different impacts on the environment, natural resources, concern issues of how people think about the world and how they communicate that thinking to
some of the applications are meteorology,oceanography,biodiversity conservation,cartography,regional planning,warfare etc.interpretation of satellite imagery is conducted by using special techniques known as remote
GIS is an emerging method of data storage and interpretation. GIS is, simply put a database. It is many tables of data organized by one common denominator, location. The data in a GIS system is organized spatially, or by its physical location on the base map. The information that is stored in the database is the location and attributes that exist in that base map, such as streets, highways, water lines, sewers, manholes, properties, and buildings, etc. each of these items don’t just exist in the database, the attributes associated with the item is also stored. A good example of this would be a specific sewer line, from and arbitrary point A to a point B. Ideally, the sewer line would be represented graphically, with a line connecting the two points or something of the like. When one retrieves the information for that line in particular, the attribute data would be shown. This data would include the size of pipe, the pipe material, the upper invert elevation, the downstream invert elevation, the date installed, and any problem history associated with that line. This is the very gist of what a GIS system is.
These days Geographic Information Systems (GIS) and Remote Sensing (RS) techniques has become a necessary issue as they help planners and decision makers to create effective and proprer decisions and designs. Remote Sensing is to look at the Earth’s surface with sensors high on top of Earth’s surface. Remote Sensing is mostly of 2 varieties Active Remote Sensing and Passive Remote Sensing. Infrared ,Microwave and Satellite Remote Sensing systems are some of the examples of Remote Sensing systems. Remote Sensing conjointly helps to assign completely different colours to different
The Global Positioning System, more commonly called the GPS is a satellite based system that provides navigation for almost everything from cell phones to automobiles. This wonderful technology is very vital in today’s economy because of its prominence in banking, financial markets, power grids, farming, construction and so much more. It also protects human life by preventing accidents, helping in search and rescue missions and is critical to nearly every facet of military operations. There are three segments that make up the global positioning system: the space segment, the control segment and the user segment. The segment we are familiar with is the user segment. The user segment is what receives GPS signals, determines the distance between a satellite and a receiver and solves the navigation equations, all in order to obtain the coordinates of a specific place. The space segment consists of 31 satellites but there is an availability of at least 24 satellites that are approximately 6 000-12 000 miles above the earth.
