Data acquisition: [Data sharing] Over 18.5 million POI data worldwide
Traditional geographic information collection methods require map surveyors to use sophisticated surveying and mapping instruments to obtain the latitude and longitude of an information point , and then mark it down. Just because the collection of POIs is a very time-consuming and laborious work, for a geographic information system , the number of POIs represents the value of the entire system to a certain extent.
Each POI contains four aspects of information, name, category, coordinates, and classification. Comprehensive POI information is essential information for enriching navigation maps. Timely POI information points can remind users of road conditions and detailed information of surrounding buildings, which is also convenient. Find all the places you need in the navigation, and choose the most convenient and smooth road to plan the route . Therefore, the number of POIs on the navigation map directly affects the usability of the navigation.
The POI dataset contains more than 18.5 million POIs around the world, and the data is organized by country or region and stored in CSV files.
