Why Should We Use Gis? Essay

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.

A Graphical Information System “is a decision support system designed specifically to analyze spatial information.” (Haag, Cummings. P.166) The graphical data demonstrated by the GIS is used to analyze roads, sewer systems, paths of hurricanes, free ways, traffic, or any graphical data that can be statistically represented.

plays a major part of our geographic information system. With all the advance technology today

For example, Whitehead and Snow came from different backgrounds and would not have been friends if Cholera did not exist. Additionally, Snow’s map would not have existed if London did not exist. Snow’s map lead to geographical based information systems (GIS) because it took a city and mapped out the number of deaths. GIS allows citizens to view a place and overlay data to find answers. An example of a GIS system is Google Maps because the program takes a map, and overlays data, such as traffic levels, to visually show results. However, the accuracy of the results depends on how frequently the data is

GIS is a computerized integrated data management system used to analyze and present geographical and spatial data.10 GIS has been used

NGA is a key player in the IC making more than just good maps. The NGA is responsible for the employment of, “Cartographers and analysts that collect and generate information about the Earth” (Szoldra, 2013) so that officials can interpret and differentiate between the make-up of Earth’s natural structures and those that are man-made. NGA creates this data for several different reasons but some of the common uses for it is land, sea, and air navigation, national security, armed forces maneuvers, and to help those in the need of disaster assistance.

Spatial data is a costly resource to generate and maintain, spatial data consumers have been unable to accurately and conveniently link with other spatial data users to share and discover useful and relevant data. There is problem of insufficient and inappropriate metadata available for the clearinghouse, metadata problems impact on effective spatial data use. The following are examples of issues associated with spatial metadata:

The RFP states that the purpose of the GIS project is to have a consultant to assess what GIS services are working for the city and what sorts of recommendations can help improve GIS services for the city’s departments. In addition, the City of Wellington has an Enterprise GIS system and conducting a needs assessment can help provide recommendations on how to share and create databases and GIS data among other city departments. Also, it is important to note that the RFP states that the consultant must bring in people who can help with outside developing outside services and products for the needs assessment. For example, the consultant might need one of his team members to create an application for providing open GIS data for all citizens in the city. Overall, this GIS project can help all the city departments to conduct a GIS analysis efficiently and thus the needs assessment can help the city improve on its six focus

Geographic Information Systems (GIS) is an essential communication tool for all disciplines world wide. Being able to communicate through imagery allows for a visual of data or information that otherwise is just words or numbers on a page. In regards to grizzly bear habitat it is important to understand the relationship of the species to the land. Making sure grizzly bears have access to food, water, hibernation habitat, and space to roam is critical to there success as a species. Grizzly bear populations, like many other animals, have had there territory greatly reduced and separated due to human activity. The remaining grizzly bears will need more access to each other or they could inbred themselves into extinction. Mapping the the different populations allows for visual understanding of how these populations can be connected.

It can be used by a company to portray GIS to about products, available at different locations, discount on the product. This gives a static picture intended to get the customers coming in. For this purpose GPS data is of little use. In majority of cases though, GIS is used along with GPS data in

This project discusses the importance of land surveying and how it has changed over time. It takes a look at the Metes and Bounds system, the Congressional/Jeffersonian system, and offshore system. Each of these systems has changed over time and is still important to the development of land surveying. This project also discusses how data is used to create land-surveying maps and where to find data. This project analyzes the data that is used with land surveying and has two maps to show how the data can be used to create maps.

Al-Kodmany formulated a GIS-based approach also helps in incorporating environmental aspects in the early phases of planning. GIS improves coherence between spatial and environmental aspects to provide means for exploring alternatives in spatial planning.

The main objective of Smart City projects is to provide sustainable infrastructure, smart amenities, faster solutions and better livelihood to the urban citizens. To achieve this, Smart City projects must utilize smart tools. One such inevitable tool is GIS – Geographic Information

The problems with BIM and GIS are hardly few and far between, but interoperability between the two has huge potential to produce benefits to the industry in areas such as security and urban planning. The introduction of Cloud computing has the possibility to vastly expand our ability to create such highly technical models. Furthermore, the importance of real-time analysis on buildings and cities can undoubtedly lead to more sophisticated, time-saving processes that ease our understanding of BIM and help invigorate smarter engineering methods. But the question we may ask is, how can this assimilation between BIM and GIS, as well as countless new technology trends, lead to better, more advanced city models in the future?

What exactly is GIS? Geographical Information System is the use of mapping the geography of a given area to gain knowledge about it. To start mapping an area you first need a base map, this can be 2-dimensional or even three dimensional. Once the base map is established, there is an endless amount of data that can be used based upon the topic. This practice of using GIS originated in the 1960’s with a nuclear arms program; now it is being used for multiple different reasons. One
