Similarwhere

Similarwhere is a term used in information retrieval and geospatial analysis to describe methods and systems that identify places that share similar characteristics with a reference location. The concept emphasizes comparing locations across multiple dimensions such as geography, demographics, climate, cultural amenities, and economic indicators, rather than relying solely on physical distance. Similarwhere systems typically represent each location as a feature vector derived from geographic information system data, points of interest, census attributes, environmental data, and user-generated signals. Similarity between places is then quantified with a metric such as cosine similarity or a learned distance in a machine-learned embedding space.

Applications of similarwhere ideas include travel and tourism recommendations, real estate market analysis, urban planning and policy evaluation, and targeted marketing, where users or decisions require locating areas with comparable profiles to a given locale. Techniques may combine structured GIS attributes with unstructured signals like images or textual reviews, and may incorporate user feedback to refine relevance.

Notes on terminology: Similarwhere is not a single standardized term; it is used informally to refer to any approach that surfaces locations similar to a target. In practice, implementations vary in data sources, feature engineering, and modeling approaches. Related areas include geographic information retrieval, spatial search, and location-based recommender systems.
