Environmental Impact Assessment (EIA) is a course of action which provides
information to various stakeholders such as planners and relevant authorities about the planned
development and its subsequent effects of the environment and the immediate ambiances.
Furthermore, the EIA and mitigation are the inclusive process of collecting, analyzing
information and the determination of the application for development or construction approval,
which could be accessible by the concerned communities and organizations. Although the set
regulations of EIA and mitigation vary from jurisdictions, they are, however, very precise and
need to be integrated with the specific geographical data. In addition, the Geographical
Information System (GIS) is a software intended to encapsulate and present all types of
physical, biological, environmental, ecological and geological information. Conversely, GIS is
the integration of statistical analysis and information technology, and can also be further
broken down into two different categories of; Topological Modelling and Map overlay. To
ensure that the EIA and mitigation are receptive the GIS will provide the decisive apparatus.
Using GIS not only improves the overall EIA and mitigation process, but also provides
valuable mapping strategies, including holistic environmental system approach. Accordingly,
the main objective of this paper is to discuss the importance of the GIS and Environmental
Data integration progression, to further enhance the overall EIA and Mitigation processes.
