Environmental Impact Analysis (EIA) is the assessment of the influence that a plan, policy or program might have or had on the environment while it was implemented. The purpose of this assessment is to help governments or non-governmental organizations to decide whether to proceed with the project or not.
How GIS can be used in environmental impact analysis?
GIS has been used to develop natural and cultural resource inventory, to identify contamination sources, to assess environmental constraints and to evaluate proposed highway alignment alternatives. GIS provides an ideal atmosphere for professionals to analyze data, to apply models and to make best decisions.
What is EIA analysis?
Environmental Impact Assessment (EIA) is a process of evaluating the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impacts, both beneficial and adverse.
What is the importance of GIS in environmental study?
GIS allows better viewing and understanding physical features and the relationships that influence in a given critical environmental condition. Factors, such as steepness of slopes, aspects, and vegetation, can be viewed and overlaid to determine various environmental parameters and impact analysis.
How is GIS used in environmental management?
GIS in managing natural resources
GIS helps in identifying the impact of human behavior on natural resources and leads to more effective utilization of the same. Data about natural resources could be collected through remote sensing, aerial photography or satellite imagery and then they are mapped using GIS technology.

A geographic information system (GIS) is a system that creates, manages, analyzes, and maps all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there).
What are the 5 components of GIS?
A working GIS integrates five key components: hardware, software, data, people, and methods.
What is the role of GIS Modelling?
The commonly accepted roles for GIS in environmental modelling are as a pre – and post – processor, preparing data files for input to the model, and displaying the model results in map form. … The proposed language may be of equal interest to environmental managers and researchers.
