A point of interest (POI) can be described as a set of coordinates that signify a location or landmark, including food services, health facilities, education facilities, and entertainment venues. City and regional planners use POI data to capture amenities in local areas, assess design plans, measure an area's economic health, learn about change over time, and visualize sites on maps. Geolocated POI data is sourced from places such as the Yellow Pages, OpenStreetMap, Google Maps, Yelp, and government registries of businesses. With advancements such as crowdsourced reviews, mobility data, and text analysis methods, we can enrich POI data with information that reflects the value and role of POIs.
