The benefits of GIS
GIS Application
A geographic information system (GIS) is a computer based tool for mapping and analyzing spatial data(it is the data or information that identifies the geographic location of features and boundaries on Earth, such as natural or constructed features, oceans, and more) . GIS technology integrates
common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps. These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining events, predicting outcomes, and planning strategies.

Methods
GIS performs six basic tasks and these are
1. Input of data
2. Map making
3. Manipulation of data
4. File management
5. Query and analysis(How far is it between two places?
• How is this particular parcel of land being used?
• What is the dominant soil type for oak forest?
• Where are all the sites suitable for relocating an endangered species?
• Where are all of the sites possessing certain characteristics?
• If I build a new highway here, how will animals in the area be affected)
6. Visualization of results
Databases & GIS
Spatial data
• At a simple level a
GIS may just form the graphical interface to a database • The majority of GIS applications follow this example
MapInfo
Linked database table
SQL Query Manager
The benefits of GIS include:
Better information management
Higher quality analysis
Ability to carry out “what if?” scenarios
Improve project efficiency
