DoE (1987: 132) asserts that GIS is defined as a system for capturing, storing, checking, manipulating, analyzing and displaying data which are spatially referenced to the Earth.
GIS has been around the block far longer than the internet and the web, with the first GIS being developed by Roger Tomlinson in 1962. This was used for Canada’s Federal Department of Forestry and Rural Development. Other than for conventionally producing maps, GIS more importantly has powerful analytical functions that translate raw data into information that is useful.(Fu & Sun, 2010)

A great example of GIS software is Arc GIS. It entails desktop GIS, Server GIS, Online GIS, ESRI Data and Mobile GIS. (ArcGIS, 2007)

Being a powerful computer mapping system, desktop GIS is a tool which manages information with respect to its location in space. There are many uses of desktop GIS e.g. businesses can optimize routes of delivery, site future businesses as well as tracking customer locations. Health care specialists can track the spread of a disease. (O’Neill et al, “n.d.”)

Being a GIS program with a reduced GIS functionality and interactive Geographic User Interface (GUI), desktop GIS is used mainly for visualization of GIS data. (Buhmann & Wiesel, 2007)

A good example of desktop GIS software is ArcGIS desktop. It is commonly used to study the trends, patterns and relationships found in the data. With ArcGIS desktop you can integrate and manage your data. (ArcGIS, 2007)

Web GIS is a combination of the geographic information system and the Web has become a swiftly developing discipline since its origins in 1993. (Fu & Sun, 2010)
The internet has helped GIS flourish unlocking the true potential of GIS from laboratories to offices. Web GIS has seen GIS...

...scalability and performance is needed for the Web GIS. * (Fu & Sun, 2010)
Web GIS can be bought by an organization and can be setup and shared by many users in contrast to setting up desktop GIS for every user which is way more costly than Web GIS.
Intended for a broad audience with little GIS knowledge, Web GIS is easier to use in general terms with desktop GIS intended for mainly professionals of GIS.
When updating GIS, desktop GIS sees the installation of updates into every computer while Web GIS needs one update to work for all clients. (Fu & Sun, 2010)

The 19th century was known for the railways, the 20th century was known for the highways, and the 21st century is known for it being the superhighway of information. Web GIS is on the fast lane of this superhighway growing and improving GIS into something that is beneficial to all. (Fu & Sun, 2010)

  • Geographical Information System - GIS

    1011 Words  | 3 Pages

    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.

  • Applications of G.I.S. in Agriculture and Ecology

    1070 Words  | 3 Pages

    Geographic Information Systems (G.I.S.) is one of the fastest growing technologies today. This field covers anything and everything that can be mapped, anything from weeds to urban sprawl, if it can be mapped, G.I.S. can be used. G.I.S. uses computers to store, analyze, and show data collected about a given topic(Kennedy 1), (Zimmerman 5-9, 73-91). G.I.S. basically turns a computer into an atlas(Kennedy 1). With all this information available, how can it help the field of agriculture? G.I.S. has been used to track the spread of noxious weeds, grasshoppers, soil types, and various other factors, which help in agriculture.

  • Essay On History Of Surveying Equipment

    632 Words  | 2 Pages

    ...h tech tools that are now used a lot of the final measurements are determined by the human eye. In the Industrial Age surveying became very important to deal with taxes and this is where the two methods came into play because geodetic were effective for a large area and took the terrain into account which was helpful for maps but plane surveying was more helpful in equally dividing up the land. Surveying became even more prominent as population grew and construction began to expand surveying for roads and bridges to just collect data as travel began to increase and ensure that the establishments could handle the new load that the increased population could handle and thus the tools began to advance dramatically from rod measurement to GPS to give more detailed reading to get further intelligence on the ground and distance more accurately using the new equipment.
