Making decisions based on geography is basic to human thinking. By understanding geography and people’s relationship to location, we can make informed decisions about the way we live on our planet. A geographic information system (GIS) is a technological tool for comprehending geography and making intelligent decisions.
GIS organizes geographic data so that a person reading a map can select data necessary for a specific project or task. A thematic map has a table of contents that allows the reader to add layers of information to a base-map of real-world locations. .
GIS maps are interactive. On the computer screen, map users can scan a GIS map in any direction, zoom in or out, and change the nature of the information contained in the map. They can choose whether to see the roads, how many roads to see, and how roads should be depicted. GIS applications can be embedded into common activities such as verifying an address. From routinely performing work-related tasks to scientifically exploring the complexities of our world, GIS gives people the geographic advantage to become more productive, more aware, and more responsive citizens of planet Earth. For any development project, the protection of water resources is extremely important. Construction over the drainage path or watershed can affect the water resources of the region. The establishment and maintenance of buffer zones along shorelines or streams is a common management practice used in ecological and environmental planning. The buffer analysis tool in GIS helps in setting buffer zones for the water bodies.
Environmental planning also addresses risks of natural hazards and disasters. The use of environmental and GIS data to construct a flood hazard map has been done for many projects.
