Along with the increase in population and the acceleration of economic growth, the urgent need for additional property that can serve as a place for various community activities also increases. It is typicalfor big cities that are the epicenter of urbanization to experience a sharp spike in land demand. One area that has excellent accessibility is Sidarjo Regency, which is comparable to SurabayaCity in this regard. This research aims to use Web-GIS to conduct spatial data analysis to identify the most suitable land functions for use in residential areas. Analytic Hierarchy Process (AHP) and Weighted Product Model (WPM) are used in this research for spatial data modeling based on multi-criteria decision-making (MCDM). Parameters were based on distance to the city center, distance to the market, distance to the hospital, distance to public transport, slope, soil type, and rainfall intensity. The results of spatial data modeling categorize the suitability of new settlement land into the categories of uninhabitable and habitable land. The K value of 0.27 is the outcome of a comparison test between the two MCDM approaches using Cohen's Kappa coefficient. The test indicates that the K value falls into the category of having a fair strength of agreement between the two methods that came into play
