A Geographic Information System (GIS) is a system designed as a comprehensive and responsive computer mapping system that stores and displays citywide data. It compares, manipulates and analyze this data by combining geography with information. One of the most notable features is the ability to create “intelligent maps” that plot multiple points of data for better analysis in a flexible, cost effective and accurate way. Therefore, the GIS is an important decision making tool that can help policy makers, planners, and researchers in taking efficient decisions related to problems that require location based analysis. A few sectors Geographic Informations Systems have been applied to are Emergency Response, Agriculture and Forestry, Census and elections. Moreover, it can be used in Energy to Security and Climate Change and so many more.During Emergency response, efficiency is key and consequently save a lot of lives. Hence, planning evacuation routes and communication networks most efficiently using prior map simulations can potentially help make a life saving decisions. Similarly, during natural disasters, when typical services such as Google Maps may not be accessible due to the loss of connectivity, mapping of civic resource locations such as the Police stations, hospitals and shelters can be extremely helpful. In Agriculture, studying crop patterns, planning locations and water distribution resources can lead to significantly reduced overall wastage. Furthermore, in the next section of this report, National Forests in Sri Lanka are identified and can also help record and capture degradation over time, migratory patterns of the wildlife and more. Census data is extremely important for any country and having up to date information on this front can help governments improve their Economy and reduce poverty. Patterns of population growth and movement is directly related to the Gross Domestic Product (GDP) of a country. Any of the above mentioned areas can be improved by orders of magnitude by any country and especially in developing countries where data in policy decision making is still not a common practice.It is also important to note that the vector data models and raster data models used for analysis and processing are organized in layers. For instance, the base layer is usually a country, city or even a district followed by another layer that usually contains the information such as population, schools in that area, vehicles or any other information needed for that particular problem. This information layer can then be used to get more insights by creating heat maps or intersecting layers using tools such as QGIS. They are sophisticated tools with automated mapping technology, database management, and spatial analysis capabilities that can enrich the services provided by governments or the private sector. The layers combined with the attribute data can generate more layers such as Zoning layer, which is in Section 6, as well as Planimetric layers,  Topographic layers and grids
