Explaining Points of Interest Data ( POI)

What is a point of interest?

Point of interest (POI) data is a type of geographic data that describes specific locations that are of interest to a particular audience or user group. POI data can include a wide range of location-based information, such as the names and addresses of businesses, landmarks, natural features, and other points of interest. This data is often used in mapping and location-based services, such as navigation apps, to help users find and learn more about the places and locations that are relevant to them. POI data can be collected and maintained by a variety of sources, including government agencies, businesses, and individual users.

How is points of interest ( POI) data generatored?

How web traffic and websites generate POI data

Web traffic and websites can generate POI data in a number of different ways. For example, when users visit a website or use a location-based service, the website or service can collect information about their location and the places they visit. This data can then be used to generate POI data, which can include information about the names, addresses, and other details of the locations visited by the users.

Third-party cookies can play a role in generating POI data by providing a way for websites and online platforms to collect and store information about the locations visited by users. When a user visits a website that uses third-party cookies, the website can store a cookie on the user’s device, which can then be used to track the user’s location and other information. This data can be used to generate user-generated POI data, which can include information about the locations visited by the user. Additionally, websites and online platforms may use third-party cookies to collect and store user-generated POI data that is contributed by users, such as the names and addresses of businesses and other points of interest. This data can then be used by other users and applications, such as mapping and location-based services.

User generated points of interest ( POI) data

User-generated POI data is geographic data that is created and contributed by individual users, rather than being collected and maintained by official sources or organizations. User-generated POI data can include a wide range of location-based information, such as the names and addresses of businesses, landmarks, and other points of interest.

This data is often generated and contributed by users who have firsthand knowledge or experience of the locations in question, which can help ensure that the data is accurate and up-to-date. User-generated POI data or crowd sourced POI data can be collected and used in a variety of ways, including in mapping and location-based services, such as navigation apps and online directories. These online platforms may allow users to contribute and edit POI data, platforms like OpenStreetMap are a good example of this allowing users to add and edit POI data, which can be used by other users and applications.

Official sources of POI data

There are many official sources of POI data, including government agencies, businesses and organizations, and online platforms. Some examples of official sources of POI data include:

  • Government agencies, such as the U.S. Census Bureau, local planning departments, and geographic information systems (GIS) departments, collect and maintain POI data as part of their official duties.
  • Businesses and organizations, such as retail stores, restaurants, and other types of establishments, often collect and maintain their own POI data, which includes information about their own locations as well as other relevant points of interest.
  • Online platforms and directories, such as Google Maps and OpenStreetMap, collect and maintain POI data that is contributed and edited by users. This data can be used by other users and applications, such as mapping and location-based services.
  • Telecommunication companies, such as cell phone carriers, often collect and maintain POI data as part of their network planning and optimization efforts.
  • Transportation agencies, such as public transit agencies, collect and maintain POI data to identify and map the locations of bus and train stops, subway stations, and other transit hubs.
  • Nonprofit organizations, such as environmental groups and cultural institutions, often collect and maintain POI data to identify and map the locations of important sites and landmarks.
  • Market research firms, such as Nielsen and GfK, collect and maintain POI data to identify potential locations for conducting surveys and focus groups.

These are just a few examples of the many official sources of POI data. There are many other organizations and institutions that collect and maintain POI data for a variety of purposes.

Challenges associated with the verification of POI data

There are several challenges associated with the verification of POI data. Some of these challenges include:

  • Keeping the data accurate and up-to-date: POI data can change rapidly, as businesses open and close, addresses change, and other factors affect the locations and information included in the data. Verifying POI data requires frequent updates and checks to ensure that the data remains accurate and relevant.
  • Ensuring the data is complete and comprehensive: POI data can be generated and contributed by a variety of sources, including businesses, government agencies, and individual users. This can make it difficult to ensure that the data is complete and covers all relevant points of interest. Verifying POI data requires checking the data against multiple sources and comparing it to other data sets to ensure that it is comprehensive.
  • Dealing with conflicting or inconsistent data: POI data can sometimes contain conflicting or inconsistent information, such as multiple names or addresses for the same location. Verifying POI data requires resolving these conflicts and inconsistencies to ensure that the data is accurate and reliable.
  • Protecting the privacy and security of the data: POI data can include sensitive and personal information, such as the names and addresses of individuals and businesses. Verifying POI data requires taking steps to protect the privacy and security of this information, such as anonymizing or encrypting the data.

Overall, verifying POI data is a complex and challenging task that requires careful attention to detail, a thorough understanding of the data, and the use of appropriate tools and techniques.
