Standardized Evaluation and GIS era
Ian McHarg popularized systematic, layered suitability analysis using overlays to inform land-use planning, laying the methodological groundwork that later GIS-enabled standardization relied on. Roger Tomlinson, the father of GIS, established the data infrastructures and analytical capabilities that made reproducible, GIS-based land-use evaluation feasible for comparing zoning, green infrastructure, and accessibility metrics. Carl Steinitz advanced planning decision-support by integrating GIS into a formal framework of cross-criteria evaluation and scenario testing, articulating urban-form typologies and performance metrics. Michael F. Goodchild contributed to GIScience and data-infrastructure standards in the 1990s, advancing interoperability and methodological rigor that underpinned reproducible land-use analyses and emerging spatial data infrastructures.
