GIS is used to monitor disaster and natural calamity prone areas. The geospatial data sets and databases allow organizations to store data of all levels. The database can contain all the information related to risk-prone areas like hospitals and isolation centres near the risk-prone zones, quick habitation centres, history of the calamities in that area, and the effect of the past disaster to plan for further contingency plans. Most Remotes Sensing and GIS is used on the areas which are prone to Volcanic eruptions and earthquakes.

Governing bodies have implemented GIS to tackle such spills. It is cost-effective than the hazardous oil spill, which is also harmful to marine life.

What is the input data for GIS?

The important input data for any GIS is digitized maps, images, spatial data and tabular data. The tabular data is generally typed on a computer using relational database management system software. Before geographic data can be used in a GIS it must be converted into a suitable digital format. The DBMS system can generate various objects such as index generation on data items, to speed up the information retrieval by a query. Maps can be digitized using a vector format in which the actual map points, lines, and polygons are stored as coordinates. Data can also be input in a raster format in which data elements are stored as cells in a grid structure (the technology details are covered in following section).

What is GIS in agriculture?

Geographical Information System (GIS) is a technology that provides the means to collect and use geographic data to assist in the development of Agriculture. A digital map is generally of much greater value than the same map printed on a paper as the digital version can be combined with other sources of data for analyzing information with a graphical presentation. The GIS software makes it possible to synthesize large amounts of different data, combining different layers of information to manage and retrieve the data in a more useful manner. GIS provides a powerful means for agricultural scientists to better service to the farmers and farming community in answering their query and helping in a better decision making to implement planning activities for the development of agriculture.

How does GIS work?

Modern GIS technologies use digital information , for which various digitized data creation methods are used. The most common method of data creation is digitization, where a hard copy map or survey plan is transferred into a digital medium through the use of a computer-aided design program with geo-referencing capabilities. With the wide availability of rectified imagery (both from satellite and aerial sources), heads-up digitizing is becoming the main avenue through which geographic data is extracted. Heads-up digitizing involves the tracing of geographic data directly on top of the aerial imagery instead of through the traditional method of tracing the geographic form on a separate digitizing tablet.

What is the most important part of GIS?

The most important component of a GIS is the data. Geographic data or Spatial data and related tabular data can be collected in-house or bought from a commercial data provider. Spatial data can be in the form of a map/remotely-sensed data such as satellite imagery and aerial photography. These data forms must be properly geo-referenced (latitude/longitude). Tabular data can be in the form attribute data that is in some way related to spatial data. Most GIS software comes with inbuilt Database Management Systems (DBMS) to create and maintain a database to help organize and manage data.

What is GIS technology?

GIS technology is of limited value without the users who manage the system and to develop plans for applying it. GIS users range from technical specialists who design and maintain the system to those who use it to help them do their everyday work. These users are largely interested in the results of the analyses and may have no interest or knowledge of the methods of analysis. The user-friendly interface of the GIS software allows the nontechnical users to have easy access to GIS analytical capabilities without needing to know detailed software commands. A simple User Interface (UI) can consist of menus and pull-down graphic windows so that the user can perform required analysis with a few key presses without needing to learn specific commands in detail.

When did GIS start?

There is some debate over when true GIS really started, thanks to the disparate technologies that came together to give us GIS as we understand it today (1), but effectively it has been around since the early 1960s. Advocates claim that it was truly born in 1962 with the first CLI conference (Canadian Land Inventory) that set out to produce masses of data of maps of Canada covering a large number of potential uses and data sets (2). The conference produced these maps using the old methods but it was first theorised here that in future, such data could be produced using the developing computing technology as data got bigger and potential to explore it became more and more complex (8).
