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).
