Question

What are the advantages of GIS over manual methods?

Answer 1

GIS possesses inherent advantages of separate data storage and presentation.
It also provides options for viewing and presenting the data in several ways.

The important advantages of GIS are given below:

1. Users can interrogate displayed spatial features and retrieve associated attribute information for analysis.
2. Maps can be drawn by querying or analysing attribute data.
3. Spatial operations (Polygon overlay or Buffering) can be applied to the integrated database to generate new sets of information.
4. Different items of attribute data can be associated with one another through shared location code.
