The full form of GIS is the Geographic Information System. It is a system that gathers, assesses, handles, manipulates, and views various geographic and spatial data. It enables you to manage big data sets, perform spatial analysis, and present and analyse the data as maps or graphs. Due to these benefits, GIS is a valuable tool for organisations to visualise geographical data or build management information systems.
- A GIS maintains data on geographic features and attributes.
- Recognized as representations of points, lines, areas, or rasters, these features. Aerial photographs can be recorded as raster data, and road records, borders, and zones can all be processed as lines and zones on a city map.
- GIS uses spatial indices to store data, making it possible to specify the attributes of any arbitrary place on a map.
- For example, a GIS can quickly identify and quantify all the places within a certain radius of a point or along all the highways and routes that travel through a territory.
- When paired with tabular data, some information might be spatial. Detail information about each spatial feature’s additional information, in particular.
- For instance, spatial data can be the precise location of hospitals within a given region. The attribute data includes more details like the hospital’s name, the level of care provided, and the number of beds.
- Through spatial analysis, GIS, which combines these many forms of information, becomes a potent tool for problem-solving.

Additional Data related to GIS features
In addition to indicating the location of features, GIS also provides additional information on features, such as:
- Relationship between one feature and other features
- where a function is performed to its minimal or minimal extent
- the number of traits present in a particular area
- What occurs inside the AOI (area of interest)
- whatever aspects of what is happening that are nearby
- How a place has changed over time.
