Environmental Impact Assessment (EIA) plays an essential role in balancing development with environmental protection.
However, many EIA processes still rely on fragmented workflows and document-centered communication, which can limit participation, and efficient collaboration among stakeholders.

The EIA scoping tool supports the early stage of the assessment process by allowing experts and planners to define the spatial scope of analysis by drawing the project site on the map, uploading spatial data such as shapefiles, or specifying locations using addresses.
Using web-based geospatial technologies such as OpenLayers, the tool allows users to explore spatial datasets, identify key environmental factors, and determine assessment boundaries.

In addition, The EIA preparation document authoring and review system enables multiple stakeholders to collaboratively prepare, review, and discuss assessment documents within a unified platform, improving the efficiency and consistency of the evaluation workflow.

Through these integrated tools, spatial technologies support more connected and collaborative environmental decision-making.
By enabling experts, agencies, and stakeholders to interact around shared geographic information, the system allows them to collaboratively define assessment areas and prepare and review EIA documents.
