GIS Essay - 1170 Words

Simply put, a GIS combines layers of information about a place to give you a better understanding of that place. What layers of information you combine depends on your purpose—finding the best location for a new store, analyzing environmental damage, viewing similar crimes in a city to detect a pattern, and so on.

This is most often in the form of a question: †¢nbsp;nbsp;nbsp;nbsp;nbsp;Where were most of the burglaries last month? †¢nbsp;nbsp;nbsp;nbsp;nbsp;How much forest is in each watershed? †¢nbsp;nbsp;nbsp;nbsp;nbsp;Which parcels are within 500 feet of this liquor store? Be as specific as possible about the question you want to answer. This will help you decide how to approach the analysis, which method to use, and how to present the results.nbsp;nbsp;nbsp;nbsp;nbsp; nbsp;nbsp;nbsp;nbsp;nbsp; This map shows the potential acoustical impacts on the surrounding area of a particular type of rocket engine. The darker the blue, the higher the decibel level, to 129 decibels. 120 decibels or lower are acceptable outside the buffer zone (the jagged line surrounding the darker areas).

Web mapping has been designed based on a client/server technology. In client/server architectures the server side is in charge of the data querying, analysis and processing, whereas the client side is based on the user interaction, map display and report generation. Web services make it easy to shareRead MoreThe Challenges Of GIS Cloud735 Words   |  3 Pagesover the internet (Zhang et al., 2010). A common framework for data with some Geoprocessing functions has been developed using GIS cloud for particular requirements (Evangelidis et al., 2014). A conventional GIS application has been upgraded to provide services over the internet as GIS cloud. The challenges in GIS applications have been achieved by a cloud computing (Bhat et al., 2011). QGIS founded by Open Source Geospatial Foundation (OSGeo) and a cloud computing spatial approach has been carriedRead MoreThe Development History Of Gis Essay2133 Words   |  9 PagesEssay on the development history of GIS Introduction This essay is about the development history of GIS (Geographical Information System). In the next paragraph the work of Charles Piquet in 1832 and John Snow in 1854 is mentioned. Furthermore the paragraph traces the development history between 1960 and 2014. It lists the development history from the Canadian GIS through the development of GPS until the launch of French satellite SPOT 7.The following paragraph defines the four major developmentRead MoreGi-Fi Technology4429 Words   |  18 Pagesintroduction of Gi-Fi technology.

It allows users to interpret data to follow trends, patterns and understand relationships analysis. The early beginnings of GIS started when French geographer Charles Picquet noted in 1832, the deaths by cholera in Paris using halftone colour gradient (De Chà ¢teauneuf, L. F. B, 1834, pg.1). John Snow is considered one of the foundersRead MoreModels Of The GIS Model832 Words   |  4 PagesGIS models have been used to combine, integrate, and interpret geological, geochemical, geophysical, and other data. These studies can be grouped based on their main goal of identify prospective geothermal areas at a regional scale, or defining specific sites for drilling a well at the local scale (Noorollahi et al., 2008). 4.1 Previous Studies Studies by Noorollahi et al., (2007) and Yousefi et al. (2007) are very similar and based on regional scale prospecting for geothermal sites. All studies
