Eco-tourism site selection is a GIS use case involving the systematic spatial analysis of environmental, infrastructural, and socioeconomic factors to identify optimal locations for sustainable tourism development. Using geospatial data from multiple sources — including satellite imagery, digital elevation models, land cover classifications, and biodiversity databases — GIS professionals overlay and evaluate criteria such as ecological sensitivity, habitat integrity, proximity to protected areas, accessibility, and carrying capacity thresholds.

The process typically employs multi-criteria evaluation (MCE) methodologies within GIS platforms, enabling analysts to assign weighted values to spatial variables and generate suitability maps that rank candidate locations. Advanced techniques such as viewshed analysis, hydrological modeling, and network analysis further refine site assessments by examining scenic quality, watershed impacts, and visitor accessibility.

From a practical standpoint, eco-tourism site selection through GIS minimizes environmental disruption by steering development away from critical habitats while maximizing economic viability for local communities. The resulting spatial decision-support outputs help planners, conservation organizations, and government agencies make evidence-based, transparent land-use decisions that balance ecological preservation with responsible tourism growth.
