Understand GIS/GPS
Geographic Information System (GIS), is defined in our text as “a computer system used to organize, store, analyze, and display geographic information. The Global Positioning System (GPS) is defined in our text as, a navigational tool consisting of a fleet of satellites orbiting Earth, broadcasting digital codes, and a portable receiver that can receive those codes and determine its location” (Dahlman & Renwick, 2015, Chapter 1). GIS has been called a way to learn the geographic reasoning for anything. We can use the GPS system to find any place anywhere on this earth. GPS operates in real-time, 24 hours per day.

Using GIS/GPS
Currently consisting of approximately 24 satellites, GPS also uses ground stations to match information and use that information as reference points of a location that is accurate to within a couple of yards. GPS was formally used strictly for the military. Now it is used in and by everything. From the cell phone to automobiles, boats and computers. GIS makes use of computer software to pass along a location on earth. The components or parts that make GIS work consist of three categories. The computer and its software, real time data, and people that are trained to use the information. The data is digitized and has been created by government or commercial operations that they make freely available in most cases. According to "Esri" (2015), GIS benefits organizations of all sizes and in almost every industry. There is a growing interest in and awareness of the economic and strategic value of GIS”.
Research if there are ways to obtain training on applying GIS/GPS in your specific career field. Would you find these types of trainings helpful? Why or why not? I am sure there are many reputable companies like Esri as mentioned in the previous paragraph. Reputable classes are offered through ESRI.com. According to their website, they build ArcGIS, which is considered one of the most powerful mapping software in the world. My particular field does not warrant my using GIS or GPS. I am sure they would be helpful to some students. I just have no use for them at this time or in the near future. My reasons being I am learning for the sheer joy of knowing something I did not know. I am currently disabled and the learning process seemed as good a thing as anything else did to do with my life. Changes that trigger other changes, such as natural disasters. How can GIS/GPS be applied to track the changes and help us understand potential threats like global warming, recurring events, or natural disasters within your perspective career field and/or regional areas. Liu (2011), “A case study in Australia is used to demonstrate use of this tool. (GIS) This shows selecting suitable genotypes of wheat is a key adaptation strategy to mitigate the impacts of climate change on wheat cropping. It shows that spring wheat genotypes will become predominate, while the winter genotypes will only be viable in clearly defined areas where sufficient days of cool temperature exist for completion of vernalisation (inducing a plant to flower) in a future warmer climate”. The tool referenced is one developed using GIS to look at the impact of climate change on agriculture and the aptitude to calculate approaches on ways to adjust.

Conclusion
The world of today has amassed new technology. Decades ago the terms GPS and GIS were things talked about in secret government rooms or discussed by the people designing new programs for IBM. 50 years ago, we humans were entering a new aspect of measuring and mapping this planet. Governments decided to share with the public what they discovered through mapping and computer programming. A great piece of luck for us. Now we can get lost, find ourselves and figure out how all at the same time. Through the ability of GIS we can determine whether and when to plant our crops. GPS can locate the misplaced auto in a parking lot by clicking on a button on our well-equipped cell phones. We are living in a geographical world of wonders. The computers, satellites and those people smart enough to use them all at the same time, make every day a marvel to enjoy. References Dahlman, C. T., & Renwick, D. (2015).

Gis and Hazards

...reasons why you think GIS technology currently requires technical experts to apply it in crisis management situations. What are the key issues that need to be addressed? Suppose you had funding resources to combat this problem, where and why would you spend that money? The debate that surrounds the issue of GIS expertise in emergency management seemingly stems from the identity and capabilities of practitioners in crisis management situations. The first or local responders in crisis situations in all likelihood will be police, fire or medical response units; who although highly skilled will not be required to possess any substantial amount of GIS knowledge. Although this observation is simplistic, the cyclical nature and/or role of GIS within emergency management convey the link between GIS expertise and emergency management. The cyclical presence of GIS in the emergency response cycle for example displays how the discipline can be involved in the process of preparedness due to its role in the process of rescue. The presence of GIS expertise in emergency management can be in part explained by the want and desire on the part GIS professionals to retain the consistency and integrity of data pertaining to any given hazard or disaster. This endeavour to build and maintain a reliable data stream facilitates more accurate and thorough long term analysis leading to the delivery of relevant short term information. Operationally the presence of GIS expertise in......

Gps Innovation

...A GPS Monster Texas A&M University Abstract GPS is a widely used phenomenon that seems to have no boundaries. From finding the quickest route home through traffic to alerting the authorities on missing persons’ whereabouts, both can be attributed to GPS implementation to almost all electronic devices. These so called shortcuts in life that this innovation brings us are limitless, but I firmly believe that we still need to be educated on the concepts for which it was created. It is a scary thought to think that the upcoming generation could be sent back to the Stone Age with a simple flip of the switch. Using innovation to enhance our lives is gratifying is nothing else, but let us not allow our total existence to be determined through our iPhone. Maps, what are those? You will not need maps where we are going. At any given moment we are somewhere according to a specific fixed location, unless you are on the fixed point then you are here. The literal point is that since 1997 anyone with a synced device with a relay transponder has the ability to precisely locate anything or anyone that has the transponder. This system of tracking locations is called a global positioning system, GPS. “Eighteen satellites, six in each of three orbital planes spaced 120º apart, and their ground stations, formed the original GPS. GPS uses these "man-made stars" or satellites as reference points to calculate geographical positions, accurate to a matter of meters”......

As such, the search for the best possible alternative from a large set of such alternatives can be a daunting task. The aim of integrating GIS with Multi-Criteria Decision Making (MCDM) is to develop a well-defined process that can scan through such extensive fields of choice to arrive at the best possible solution. Goal Programming is one tool (developed in conjunction with MCDM) that can handle a problem with multiple, conflicting and incommensurable alternatives, and this article explains how the loose coupling technique can integrate MCDM with GIS to assist decision making among competing alternatives. As an example, this methodology has been applied for community development purposes in the Hooghly District of West Bengal, India. 1 Background The inclusion of...

...GASTROINTESTINAL INTUBATION Clients, especially those undergoing abdominal or gastrointestinal (GI) surgery, may require some type of tube placed within their stomachs or intestines gastrointestinal tubes provide nourishment to client who cannot eat. First, let’s take a look at which patients may be candidates for tube feeding .Patients with chronic illness or psychiatric or neurologic disorder ,such as alcoholism, chronic depression, or anorexia .Patients who are debilitated because of disease or injury .Patients undergoing maxillofacial or cervical surgery resulting from disease or injury. Patients with or pharyngeal or esophageal paralysis resulting from disease or injury, neoplasm, inflammation, trauma, or respitory failure. Tube feeding are not a one-size-fits- all measurement they have proximal and distal end, their size, construction, and composition vary according to their use. Tubes are measure by using the French scale each number on the scale equal approximately 0.33mm. The larger the number, the larger the diameter of the tube. That is one of the reason‘s why every patients condition is considered individually to determine whether which tube feeding is best for the patients specific condition and needs. Secondly, let’s discussed where the tubes maybe placed any why. Tubes can be identified according to the location of insertion, or there distal end. The choice of feeding route is based on the patient’s medical status, aspiration, and expected duration of...

...provider in Nigeria. Lamplight has high technology equipment, and products (GPS tracking systems and panic button) that will enhance the security and safety movement of resources across the country to a whole new level. Lamplight will quickly establish itself as the first provider of such products and services in the country and will acquire a licence that allows only lamplight to be a provider of these security services in the country. Lamplight will be introducing two products, GPS tracking systems and the panic button, as stated earlier. Lamplight will target the transportation and security companies and individuals. GPS tracking systems consist of a device installed in the vehicle, a central server and software for the owner to access information. Data from Global Positioning System satellites will be used to determine a vehicle’s location, speed and direction of travel. It is no secret that that there is a relatively high level of corruption in the country, hence the reason why GPS tracking systems will be of great benefits, especially for the transportation industry in the country. How will these GPS tracking devices be used? For example, when transporting oil or fuel across the country, drivers will be given a specific route to follow and times and places to stop for a break. Note that some of these drivers often stop to sell some of these oil or fuel solely for their profit. This is where the GPs tracking systems come into play because if a driver goes off the......

The brush border contains numerous digestive enzymes. The enzymes secretin and cholecystokinin are secreted by intestinal mucosa. Pancreas and gallbladder: The pancreas delivers digestive enzymes and bicarbonate to the duodenum. The gallbladder delivers bile salts to the duodenum. Large intestine: Reabsorption of water and storage of feces. Feces are delivered to the rectum for defecation (pgs. 805-812). 2. How does the autonomic nervous system influence gastrointestinal motility? Sympathetic nervous system activity is generally inhibitory to GI motility and secretion. Parasympathetic nervous system activity generally enhances motility (pgs. 813-814). 3. How do segmental and propulsive movements influence the digestive and absorptive functions of the small intestine? Segmental and propulsive movement mixes the chyme and digestive enzymes to enhance digestion and spreads out the chyme along the intestinal mucosa to aid absorption (pg. 818-820). 4.

Implementing Gis

...IMPLEMENTING GIS Abstract This paper tries to study the GIS implementation in the state of Arkansas and tries to identify the potential of using the Arkansas GeoStor implementation blueprint for similar application in other states. The paper also tries to identify the differences which may be required in the system if the blueprint is to be used for other states. The factors affecting these differences would also be identified and the expected value realizations for other states as compared to the state of Arkansas. Expanding Business Intelligence to GISs Governments around the world have lots of location based data which is very important for managing the state and serving the citizens. Having all this data in physical formats makes it very difficult to manage and work efficiently. GIS systems are invcreasingly being used to convery the location based data into digital formats. A lot of different government agencies require location based data which is useful to their field area. Having multiple government agencies using different sets of location based data can make colloobration very difficult and time consuming. Integrating the location based data from various government agencies into a single data warehouse can go a long way in helping not only government agencies but also other businesses to take advantage from it.

Expanded Applications of Gis/Gps

...Expanded applications of GIS/GPS Pamela Armstrong GEO/215 December 8th, 2015 Zahid Vermani Expanded applications of GIS/GPS Geography gives visualization to the world around us and helps identify different types of environments and our relation to their development. Through time humans have employed new and advancing geographical tools to help describe the world. For example, one of the first geological tools used to describe the planet were maps and over the years they have become increasingly detailed and interactive. The current geological tools incorporate maps and computer technologies known as GIS and GPS. Continuously, GIS stands for geographic information systems, and it combines visual data concerning information about shapes, sizes, and locations that can be analyzed. The power of a GIS is its ability to analyze location, features or objects (such as a stream), and feature characteristics (such as water quality, direction of flow), in relation to other locations, features, and their characteristics (National Park Service US Department of Interior, n.d.). GPS is defined as a global positioning system using satellites to accurately pinpoint locations and give directions to other locations by using satellites that orbit the earth. With this in mind, a combination of these two tools help to give a 3d image of the earth and bring all its geological features to life but most importantly they can be used to analyze information to help improve many areas of......

Expanded Application of Gis/Gps

...Expanded Application of GIS/GPS When I started my GEO 215 class I was quite unsure exactly what we would be talking about. First thing that came to mind was maps, then it was on different areas in the world, then how different cultures survive and adapt to different areas etc. So my mind began wondering down this Geography journey. So once I got the first assignment about the Expanded Application if GIS and GPS, I was stomped. So of course that's exactly where I started my research. First thing I looked up was what is GIS or Graphic Information Systems. "A GIS combines visual data concerning information about shapes, sizes, and locations that can be analyzed" (Wikipedia 2016). A GPS also known as global positioning system uses satellites to pinpoint locations and give directions to other places by using satellites that orbit the the earth. So the more I read the more I realized how these two tools play a major role in Geography. Geography gives visualization to the world around us and helps identify different types of environments and our relation to their development. When you bring these two types of geographical tools together you will be able have to analyze information to let you know the unknowns of the world. For instance when you get the information from you GIS or GPS or can tell you if there is traffic ahead or if the weather is bad or if there is a river ahead. We use GIS and GPS all around the world. The satellites help share the collected information all......

Gi Joe

...G.I. Joe has been a brand in the market for toys since its launch in 1964 with $3 billion in sales over the last 20 years, with 16% of the market share. Despite the brands success the GI Joe is positioned as a physical product, as appose to an all-encompassing brand and the toy market has volatile sales depending upon trends created by consumer demand. Hasbro is now challenged to take the G.I. Joe brand to the next level and market it in such a way that will allow the brand continues to thrive while preserving the brands legacy. One major issue facing G.I. Joe besides their competitor Barbie (Mattel) is that the industry has changed drastically in the last decade. The target customer for G.I. Joe is a shrinking market due to technologically savvy youths who prefer playing electronic games as opposed to playing with action figures. In addition, lifecycles within the industry are also getting weak, with 70% of sales belonging to toys released within the last 3 to 4 years. Manufacturers have also adopted a more short-term goal oriented strategy based on the creation of the “instant gratification” attitude among their target market. Retailers have joined manufacturers in shifting their strategies to focus on multipurpose department stores as the primary location to purchase toys, with the top five players comprising 75% of sales of toys in 2003. This has a major effect on one of Hasbro’s core strengths (see appendix) a unique relationship with retailers which is a key asset......

Gps at Disneyland

...Global Positioning System (GPS) receivers and radios are of immense use even at an unassuming place such as an amusement park. This case study discusses how a family with children visited Disneyland and Disney's California Adventure Park taking along with them a GPS receiver. This GPS receiver was a Garmin seventy six cs, and came with four GPS radios that were Rino five hundred and twenty HCx. The family initially used the GPS receiver with the standard basemap, and later with the StoneMaps. The case study tries to understand how the family used these units and made good use of the radios. These radios turned out most useful as a means of communications given they were often in a crowd and split up from time to time to explore different amusements. The GPS receiver was also a help because children tended to wander away. The paper highlights how the equipment maximized the family's time and fun by offering a ready guide around the place, activities and a tracking and communication system that involved the children as well. It discusses the details offered on the maps. The paper points out that the maps are uncluttered and they are visually clear and appealing on a color screen. The available maps are also compatible with older units. They offer an overview when zoomed out and display details when zoomed in. The paper also offers details on the waterproof features of the Rino GPS units along with the carry a backlight for use at night facility....
