GIS as Decision Support System
Track: Teaching with GIS in Higher Education
Author
Geographical Information System (GIS) is a computer based information system that enables capturing, modeling, manipulation, retrieval, analysis, and presentation of geographically referenced data. It is a facility for preparing, presenting, and interpreting facts that pertain to the surface of the earth. For efficient digital mapping, there is a need to have a well defined Decision Support System (DSS) so that the purpose of mapping can be achieved and it is implemented in an efficacious manner. Various capabilities of GIS may be utilized for mapping in a digital platform, which may include locating monitoring stations, identifying landslide susceptible zones, ground water exploration, etc. By doing ground water explorations, flood monitoring, earthquake zonation, etc. under GIS environment, the output of the whole process can be obtained in the form of spatial records. GIS techniques are capable of locating most accurate ground water prospects zones on the basis of Index Overlay Method.
