What is the goal of site suitability analysis in GIS?

The goal of site suitability analysis in GIS is to identify optimal locations for specific uses or activities. This process involves analyzing various factors, including environmental, economic, and social criteria, to determine how well a particular location meets the requirements for a given purpose, such as urban development, agriculture, conservation, or facility placement.

By utilizing different GIS tools and techniques, practitioners can create suitability maps that visually represent areas that meet the necessary conditions for specific sites. For instance, if planning for a new school, the analysis might evaluate proximity to residential areas, accessibility, environmental concerns, and existing infrastructure, leading to informed decision-making.

In contrast, mapping all geographical features focuses broadly on data representation rather than specific analysis for optimal site selection. Evaluating historical land usage provides insights into past patterns, but it does not directly aid in determining suitability for current or future uses. Similarly, assessing potential land value can inform economic considerations but does not encompass the comprehensive analysis of multiple factors needed for effective site suitability assessments.
