Data analysis in GIS:

Therefore, GIS consists of the following:

1.  Database - for storage and retrieval of information. The database forms the foundation of the GIS system. All the data about the GIS system is stored in the database.

2.  Base map - for geo-referencing of the network system.

3.  GPS points - for picking up the actual location (latitude/longitude) of several network components.

4.  User interface - for accomplishing several tasks of reports, query, and analysis. In a nutshell, we can say in which the GIS technology

• integrates general database operations (data query and statistical analysis), along with the unique benefits of visualization and conceptual spatial analysis offered through maps;
• optimizes data layering (spatial overlays for object relationship identification),
• allows for effective and timely data management (particularly data updates).
