Digital Image Analysis of Yellowstone National Park
Introduction
Remote sensing refers to the tele-observational surveying and mapping of physical, urban and environmental features. Remote Sensing is also a composite of many other subjects such as aerial photography, radar surveying, thermal surveying, weather forecasting and photogrammetry. It has now become quite common practice to use remotely sensed data to take inventory, monitor and develop effective management practices of our natural resources.
Objective
It is the purpose of this paper to further enhance the understanding of remotely sensed data in such a way that we may assist the human brain in the extraction and interpretation of this data through digital image analysis data manipulation techniques, such as rectification, enhancement and classification. The application of conventional and non-conventional image enhancement /classification procedures will be applied to an area of The Old Faithful section of the North Fork forest fire within Yellowstone National Park as it existed on September 8, 1988. They will also be applied to Nile Delta region of Egypt.
Conventional technology in the context of this paper refers to imagery that is uni-dimensional, that is, it has only one spectral band available for analysis. The term non-conventional will refer to imagery that has multi bands available for manipulation and analysis.
Methods of enhancement utilized in the multi-band portion of this project include:
- colour and histogram image enhancement
- normalization and image algebra enhancement
- filtering image enhancement
- band transformations (eigen pictures) image enhancement
- coventional methods of enhancement
Methods of classification utilized in this project include:
- signature training ( sampling)
- supervised classification, PPD, Mindis, Maximumlikliehood
- unsupervised classification, histogram equalization, clustering
Methods of enhancement used in uni-scene portion of this project include:
- histogram equalization uni-band
- filtering image enhancement
Data Acqisition
Data acquisition refers to the data by means of information gathering about the scale selection of the remote sensing formats and the target identification of the surveyed and mapped resources.
In this analysis we have acquired Landsat Thematic Mapper data which consists of seven spectral bands and covers a 512x512 picture element area. The Landsat ground resolution or pixel size is 30x30 metres which translates to an area coverage of 235.93 square kilometres of ground coverage, which is a subset region of the Yellowstone National Park.
The Nile Delta region is located in nothern Egypt and the data acquired was originally acquired for delta topgraphy. The data is Landsat MSS with one available band and covers a 580x640 picture element area. The Landsat MSS ground resolution is 80x80 metres which translates to an area coverage 2211.
The movie Dope, written and directed by Rick Famuyiwa, follows the story of Malcolm through his senior year of high school in the Inglewood California. He lives in a poor neighborhood, with only his mom, yet he still strives for greatness. He has a couple of friends, and they all love 90’s hip hop culture. They try to do their best to stay out of trouble and away from bullies. Malcolm sees a girl he likes and ends up following her to a drug dealer’s birthday party. When the cops bust the birthday party, he unknowingly goes home with all the drugs and the gun that the drug dealer owns. This sets off a wild chain reaction, as he now has to sell these drugs to payoff the supplier, who happens to be the Harvard Alumni that Malcolm’s needs approval
The effective use of color and imagery by an author, combined with poetic language can give the reader a detailed image in their mind. Edith Wharton uses this technique in her writing in the novella Ethan Frome. Using imagery, the author paints a vivid picture with words using color to set moods, develop characters, and foreshadow coming events allowing the reader to fully experience the world of Ethan Frome.
One of these is infrared satellite imagery. This is explained in paragraph 2-"Infrared satellite imagery can locate objects on the ground less than two feet wide. Infrared light also can penetrate about a foot below the surface and detect differences in the soil." At first, this might seem like a great idea. But it has plenty of cons. In paragraph 4, it is explained that infrared satellite imagery needs manual help in order to reveal any discoveries, and that takes lots of time. It goes on in paragraph 6, stating that infrared cannot be used in jungles, which is exactly where many ancient civilizations hide, buried beneath the tree canopies. It also doesn't scan very deep, so anything over a foot below the surface will remain undescoverd. Another technique is brought up in paragraph 11, called Ground Penetrating Radar (GPR). "The GPR sent pulses of microwave energy underground, where it bounced off buried objects. They used state of the art software to analyze the radar echoes and constructed a 3D map," (Paragraph 11). Once again, this technology has serious negatives. Scientists had to drag this bulky lawnmover-like machine in blazing heat across the jungle floor (paragraph 11). This machine is great for a workout, but not it you want to discover lost civilizations
The Three Here’s for Cooking The romantic comedy, Today’s Special, expressed the worries of Indian parents becoming at ease. Also, expressed the struggles a parent faces in search of a better life, the passion and dedication going unnoticed in the work field, and the connection between friends, a lover, and family. However, the film centered its attention more on the development of Samir’s “cold” cooking within the Indian food, with the help of Akbar. In addition, the main actors in the film looked the part and associated with the main idea of the culture of an Indian family. For instance, Samir’s appearance showed he had drifted away from his family’s culture and developed a professional understanding and love for the cooking industry.

In his documentary Classified X, Martin Van Peebles describes three areas where African-Americans could be receive some sanctuary from the racism that pervaded almost all Hollywood films. These three places were: the Hollywood version of an all-Black film, the church, and entertainment. Black culture and music is prominent in mainstream society, but the people behind this culture don’t always receive recognition and respect for their creations. Mainstream White pop culture excitedly consumes and appropriates Black culture, but disrespects the source.
Mask a 1985 film about the life of Rocky Dennis who has craniodiaphyseal dysplasia. Those who don’t know him personally tend to make assumptions and bully him, but he has his extended family to protect him. His mother fights all that oppose him including the principal who because of Rocky 's features wishes to place him in a specialized school. A few of his classmates are able to accept him because of how smart he is. He even tutors others student for money to take a trip around europe. After he graduated high school, he accepted a position to teach at a summer camp for the blind. There he ends up falling in love with Diana Adams whose parents object to their relationship. Some time after that Rocky goes to sleep with a horrible headache
The movie Shock Doctrine revolves around the concept of the same name. The film begins by discussing psychological research on the effects of shock therapy. It is evident that a person under extreme stress and anxiety commonly experienced during a crisis functions and performs inadequately. It is noted that the studies are conducted by a man by the name of Milton Friedman, from the University of Chicago; the studies took place in the past, and some of the subjects are still recovering in the aftermath. From this research, interrogation techniques were learned and the concept of the shock doctrine was formed. Essentially through causing a crisis, the population of a country can be shocked into complying with accepting laws that favors the United States and capitalism. This theory coexists with Friedman’s belief in that government regulation is bad, and through a crisis a country would better itself with deregulation. The video uses Chile as an example and shows how America allowed a crisis to occur in Chile, through coups, interrogations and subterfuge. In the end a new government is formed that allows capitalism. Unfortunately afterwards violence and riots occur, as the rich gain most of the wealth and poverty rises. In addition to Chile, Argentina, Russia and even Iraq underwent the shock doctrine. Almost in every account, poverty rises and violence ends up erupting. The movie ends by showing how the US was in the process of the shock doctrine, and still is but the population has taken notice. Protests such as Occupy Wall Street are some of the initiatives necessary to bring awareness to the problems of class inequalities in order to prevent capitalism from benefitting the rich and increasing the wealth gap among the classes.

Analysis of Film Posters Having studied film posters this term, it is apparent that certain forms and conventions are applied. [IMAGE]The major forms and conventions of film posters could include: A large title which attracts the eye, bold colours which stand out from the background, intriguing picture which would attract viewers to the film, persuasive language which might persuade the viewers to go and see the film, using the main character's name for promotion, and the certification will either to ensure that the right type of people are watching the film. An example of how different types of film (e.g. comedy, horror) poster use these forms and conventions to attract a certain type of person (e.g. teenagers, horror fans) would be a really scary horror film, which will use eerie images in order to appeal to horror fans. A successful film poster will accomplish attracting the target audience and persuade them to come and watch the film.
First of all, I think that Sound and Fury was an appropriate film for us to view and analyze in this class. I enjoyed the lecture given after we viewed it, epically because it was brought to my attention that the follow up film was funded by people who make cochlear implants. We were reminded that not all documentaries are non-fiction or unbiased! I really appreciated that because I love watching documentaries (I think I needed that reminder). I also enjoyed the film, I thought it was interesting because I knew very little about the deaf word before. I have a hearing friend whose parents are both deaf, Sound and Fury made me much more curious about her childhood and how she and her sister developed speech. It also opened my eyes to how important deaf culture can be to deaf people!
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.
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.
Ecology and environmental systems is the science and engineering of a system that is apart of our surroundings. These scientists use GIS in Ecology/ environmental systems to study, measure, improve and manage our environment. An example of the use GIS in Ecology, environmental systems is in the article I found named Simplifies Italian Hazardous Incident Response; this article explains how a devastating earthquake had struck northern Italy in 2012. A GIS company provided support by helping prevent or manage any potential loss of ...
