Geospatial technology can enhance environmental impact assessments by gathering different types of spatial data relevant to projects, conducting analysis to identify affected areas and stakeholders, and presenting results in interactive maps. The document discusses how tools like satellite data, mobile data collection, and geographic information systems can be used to map land use, identify households affected by projects in Nepal and oil concessions in South Sudan, and present results through maps of affected areas in Arizona and Armenia that obtain community reaction and input. Geospatial visualization improves understanding of relationships between people and the environment and the communication of impact assessment results.
