A spatial interaction model is used to map and model the interactivity between various factors in distinct locations, making it useful for understanding data with multiple location components. This technique can be applied to various fields such as retail, commercial real estate, public transit, city planning, and conservation efforts. By using a spatial interaction model, businesses and organizations can gain insights into how attractive a particular new location is, predict the flow between new locations, and understand the impact of their decisions on their customers or target audience. The models can also be used to assess the expansion of public transit, evaluate the effectiveness of conservation efforts, and inform decision-making in various sectors.
