The Development History Of Gis

From the book, it can be learned to keep cities clean and find ways to dispose of all human waste. It can also be learned that from this book people can begin to understand confirmation bias. When doing research people often only find information to back their hypothesis, and what needs to happen is the researcher must look at the data from every angle so they can find the truth. The map itself also led to the creation of Geographic Information Systems. GISs are extremely helpful in today’s society because it can help show data in a new form that is easier to understand. It also makes it to where different data can be layered. Also a lot can be learned about data collection from this book. John Snow had a lot of data to collect, and he also had to find ways to graph it. He could have just as easily wrote down all the addresses and how many people died there, but he chose to make the map, and it made it possible to physically see where the concentration was. All of these things that was discussed throughout the seminar, the book, and timelines taught me a lot. I leaned that zooming in and out of data can change its perspective monumentally, and it makes it where you could prove a point even if when you back up, the same point would not be made. I also learned that we use GIS every day, and we do not even realize it. Finally, it taught me to never take advantage of

Some of the major technologies used in geography, have made both sorts of information far more readily available and far easier to use. Statistical analysis and modeling of spatial patterns have relied on computer technology.

(1999) state that ‘Geo-Spatial Information Science is a comprehensive and integrated information science and technology, which is used to acquire, measure, analysis, store, manage, display, diffuse and apply the data related to earth and spatial distribution.’ Furthermore, with the continuing effects of human activity upon the environment becoming more apparent in the form of climate change, the Geomatics industry is becoming more important in mapping temporal changes and spatial distribution especially in the case of natural disasters, but is also significant due to globalisation, in mapping social, economic or distribution aspects globally and locally.

Answer: - Coordinate system is actually a reference system which represents the geographic locations, images, GPS (Geographic Positioning System) locations present in a common geographical framework. Hence these coordinate systems allows the geographic datasets to use the common locations for the purpose of integration.

2. Acquiring geographic information: Geographic information is information about locations, the physical and human characteristics of those locations, and the geographic activities and conditions of the people who live in those places (NGS).

In chapter 1 the first map he discusses is the old one, the trusty rusty, the map you almost fell asleep looking at in high school world geography. The paper multi-fold map. Jennings explains that he could stare at those maps for hours upon hours. For him it was like being on a never ending vacation. The places he would visit by imagination and the names of those places absolutely drew him in and held him in an utter fascination. He felt as if he could sit on the highest point in Arkansas all from his dimly lit room seated in a recliner. The world was endless; he could go anywhere he wanted without spending anything but his time.

1. ) With new technology such as Satellites scanning the surface of the earth, cartographers can use geographic information science or (GIS) to help them make more detailed and accurate maps. This has allowed scientists to get very precise and complex information from all of the data coming from the satellite orbiting around the earth at all different distances and angles. Another use for all of the Satellites is remote sensing, this allows satellite images to be scanned in thin lines any time a satellite could scan a small area or a pixel. With this we can look at very small features of earth from space and removals send it back down to earth for Analysis. A scientist can use this tech for making very accurate maps about features such as population

Before understanding why geography tools are important, know what they are. There are many different types of maps. Physical, climate, economic, topographical, political, road, and many more. Things such as an atlas, globe, aerial photographs, satellite photograph, graphs, and GIS systems are also important in a geographer's line of work. A GIS is a computer program

Maps are a very useful tool for us to use. Maps are timeless, we still study maps from thousands of years ago. Cartography is the science of making maps. The map that I will be writing about in this paper is a map of North Carolina, showing the loss of good agricultural lands to urban development.

-A map is useful for finding the shortest distance between two places when it is used as a

If there is a certain illness that is targeting one area of a map, then it is easier to narrow down the cause of the illness. Maps can also help us learn where we need to build hospitals, urgent care facilities, and doctor’s offices. Mapping crime lets us know where “hot spots” are located. If we know that a specific area has a higher crime rate, we can increase the police presence in that area to stop the crime before it happens. Mapping of crime and public health have helped the government and general public learn how to improve the quality of life for the people living in that area.

The first Cholera epidemic in England appeared in October of 1831. Symptoms of Cholera include dehydration, diarrhea, fever, and vomiting. Soon the disease would take over the patient's body and kill them. The second epidemic took place in 1848 through 1849 and killed almost 70,000 people throughout England and Wales. Doctors could not figure out the source of the illness or how to cure it. The living conditions made this illness spread like wildfire. People were living in cramped living areas and did not have proper sewage systems. Human waste was thrown into ditches and alleyways. When the city would flood the sewage would flow into houses, marketplaces, streets, and eventually made its way into streams and the Thames river. Doctor

While the original Daguerreotype started a massive surge on photography, two later inventions turned photography social phenomenon that became ingrained in our lives today. The first of these inventions is called the “calotype” process. invented in 1839 by William Henry Fox Talbot this method of photography involved exposing chemically treated paper, producing a “negative” that could be redeveloped. This allow for multiple copies of the same image to be printed, and is the predecessor to modern film photography. The next major breakthrough in the art of photography was the portable camera. Before its inception, most photos were taken using a large, cumbersome device that worked as a camera and darkroom for developing glass plates coated with a sticky collodion solution. (film photography was

* Geostatistics is a branch of geography that deals with the analysis of data from disciplines such as petroleum geology,hydrogeology, hydrology, meteorology, oceanography, geochemistry, geography.

With the invention of complicated printing technology in the 1870s, photographic images were possibly created for the reproduction in newspapers and magazines.
