Map Properties and Locating Objects

Part A: 1) The lag between the map’s geographic data and the map’s publication date is 3-4 years. This is important; as with in those 3-4 years there could be changes in the landscape of the mapped area that may not have been present at the time the geographic data of the area was taken or during the production stages of the map. 2) The NTS sheet number for the map is 30 M/5. Sheet numbers for the surrounding maps are: west, 40 P/8, north 30 M/12, and south 30 M/4. Part B: 1) The map projection used for this map is the Transverse Mercator Projection. The cartographer who invented this projection system is Gerardus Mercator.

2) The cartographer who invented this projection system is Gerardus Mercator. 3) The two coordinate systems used in this map are Universal Transverse Mercator system, using meters, and Longitude & Latitude, using degrees. 4) The distance of one side of a UTM grid cell is 1000m 5) UTM zone for this map is zone 17 6) The map is located east of the central meridian of its UTM zone 7) The datum of the NTS sheet is the North American Datum 1927 and the most recent North American Datum is 1983. Part C: 1) The scale of the NTS sheet is 150000 2) 5cm on the map is equivalent to 2.5km. 1cm: 50000cm = 1cm: 0.5km 5 cm: 2.5km 3) The surface are represented on the map is 1000 km2 4) Other scale used to publish NTS maps is the 1250000 scale.

6.2) The topographic profile for transects 1 tells us that it is a steep climb as the increase in elevation is rapid could be a mountainous region. The topographic profile for transect 2 shows a much less steepness but there is constant increase and decrease of elevation could be bumpy or uneven…...

Object Oriente

...d1.1 Object-oriented programming (OOP) is a programming language model organized around "objects" rather than "actions" and data rather than logic. Historically, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data. Object-oriented programming is a programming paradigm that uses abstraction (in the form of classes and objects) to create models based on the real world environment.   An object-oriented application uses a collection of objects, which communicate by passing messages to request services. Objects are capable of passing messages, receiving messages, and processing data. The aim of object-oriented programming is to try to increase the flexibility and maintainability of programs. Because programs created using an OO language are modular, they can be easier to develop, and are simpler to understand after development. The characteristics of object oriented programming are as follows: 1. Class A class is a blueprint, or prototype, that defines the variables (data) and the methods (operations) common to all objects of a certain kind. 2. Object Objects are the basic run time entities in an object oriented system. They may represent a person, a, place, a bank account, a table of data or any item that the program has to handle. Objects take up space in memory and have an associated address like record in Pascal, or a structure in C. 3. Encapsulation The act of placing data and the operations that......

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......

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...

Gi Intubation

...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...

The Document Object Model

...Document Object Model May 8, 2011 IT/238 Van Hook The Document Object Model (DOM) is an important part of creating animation and making web pages interactive. The Document Object Model is used with Dynamic HTML to help accomplish the interactive web pages that are used today. “Dynamic HTML(DHTML) refers to a combination of technologies that make Web pages dynamic…a combination of JavaScript, XHTML, CSS, and the Document Object Model” (Gosselin, 2008, pg. 485). The Document object Model is all the HTML that is displayed on a web page from the web browser. Each of the many elements contained in the web page are considered objects and can be controlled and changed by using JavaScript. The Document object Model gives you the ability to change these elements without the web page needed to be reloaded. The HTML DOM can be used to dynamically change the document object and to change and control elements like images, which can themselves be considered the image object. The Document object and the image object both contain methods and properties that can be used to dynamically change the web page. The methods used with the document object are close, open, getElementById, getElementsByName, getElementsByTagName, write and writeIn. The open method creates a new window or a frame. The close method closes the document that was opened with the open method. The getElementById method retrieves an element by the specified ID. The getElementsByName method retrieves an...

Iphone Real-Estate Property

...more for themselves. They want a good life style, a good home. Now, when one plans to buy a property, one of the biggest challenges he/she faces is locating a property. Before the Internet, people used to first contact real estate agents, who had a limited list of properties in their database or you could drive around a neighborhood. For people wanting to locate properties themselves, the Internet offers a good alternative. A lot of websites now cater to this need. People can go to these websites and get results. But this is the era of devices like smartphones, etc. The last couple of years have seen a huge increase in the sale of smartphone devices. iPhone devices constitute the third largest population of all the smartphones and in the USA they are ranked second in smartphone sales. Nobody wants to just look for a property while sitting at home. People also want to go out and look for a property and if they do not find it good, then search for another one, after lunch maybe. A smartphone is useful during lunch. With the advancement of the latest wireless technology and devices, mobile professionals and companies came up with smartphones to provide the solution to such problems. They are capable of giving the user the ability to connect to the Internet. But, thinking from a user’s point of view, it is not a good experience going to a mobile browser and hunt a property over there. Mobile browsers have limitations of their own. It’s not the same experience......

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......

Geographic Information Systems (Gis)

...The term Geographic Information Systems (GIS) is a term used to refer to a system installed in a computer capable of manipulating, assembling, displaying and storing information that has been geographically referenced. Large volumes of data are mapped, analyzed and modeled using a single database depending on their locations. In short, the software gives one power to create maps. Information such latitudes, longitudes, elevations and ZIP codes are fed into the system and the results can be used to determine whether and climate patterns of different regions (Global Geographic Information Systems, 2007). Different organizations use GIS generated data to seek information regarding specific areas of interest they are interested in. Organizations such as the World Health Organization used the software to map different areas. For instance, GIS is used to map areas that have been struck by polio. The World Health Organization which is a world-wide specialized agency also employs GIS in its management. The organization was established in the year 1948 and it has its headquarters in Geneva, Switzerland. It is part of United Nation and its major role is to deal with international public health. The organization covers a large geographical area and hence the need to use a specialized system to monitor its activities. The organization has employed the GIS to help eradicate some of its most annoying challenges; polio. The fight against olio is estimated to have a 99% failure rate, but......

The Logistic Map

...know that there are three types of attractors: static or fixed point attractors, limit cycles or periodic attractors, and “chaotic” attractors. These three types of attractors have been illustrated for the equation x(t + 1) = rx(t)[1 − x(t)] which is a simplified form of the discrete version of the logistic model. These illustrations are widely present in the literature of the eighties of last century, and showed the existence of what we now call chaos, for values of the 10 H. Pastijn parameter r beyond 3. This logistic model is a member of a quadratic family [the right hand side is of the second degree in x(t)]. It is also a member of a larger family of single peaked functions in the right hand side of the equation, for which general properties with respect to the chaotic behaviour have been studied. Last century many variants and generalizations of the logistic model have been introduced to describe the diffusion of new products and of technological innovations. These models have been summarized by De Palma et al. [1]. The most well-known are those of Gompertz (see supra), Blumberg with the differential equation dx/dt = rxa (1 − xb /k), Bertalanffy with the differential equation dx/dt = r1 xm − r2 xn , Bass with the differential equation dx/dt = (a + bk/x)(K − x), all with positive parameters. The Bass model was describing the evolution of several consumer goods markets in the USA (refrigerators, TV-sets, air-conditioners,. . . ) during the second half of last century. Several......

Investigating Secondary Dispersion Patterns of Indicator Minerals Using Gis

...Picturing the Subsurface With GIS: Data Visualization Techniques for Geophysical Images Using ArcGIS By Lucas Donny Setijadji Geoscientists try to understand the earth's crust using geophysical methods such as gravity and magnetic surveys. Mining geologists also use geophysics to search new mineral deposits. In areas such as the Nevada Great Basin, geoscientists rely more on geophysical images than on geologic maps. The Great Basin area holds one of the biggest mineral concentrations in the world. Economically, gold is the most prominent commodity. The most important gold deposits are hosted by carbonate rocks, called the Carlin-type and Carlin-like gold deposits. Carlin-type and Carlin-like gold deposits are unique geologically, are abundant in Nevada, and are hardly found elsewhere. Although much research has been done, a lot of the geology is still unclear. This paper discusses how ArcGIS provides a tool for research on mineral resources. Emphasis is on the functionality of ArcGIS to handle multiple data sets and maps as well as data visualization techniques using ArcGIS. Great Basin Geology Figure 1 shows the distribution of known gold deposits combined with topography, young geologic rocks, and county lines. Data sets were downloaded and compiled from several United States Geological Survey (USGS) Web sites (e.g., Raines et al., 1996). Data processing was done using ArcGIS 8.3 and its 3D Analyst extension. The Great Basin is complicated by its......

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......
