Title: METHOD AND DEVICE FOR DETERMINING AREAS OF INTEREST BASED ON GEOLOCATION DATA
Abstract:
The present application provides a method and a device for determining an area of interest based on geolocation data. The method comprises: performing gridding on a map area to be processed; recording a grid value of each grid within a preset duration, the grid value being the number of users that report geolocation data within a corresponding grid; selecting a grid value greater than a preset threshold from the recorded grid values; determining location points in the grid corresponding to the selected grid value; calculating, according to the location points and based on a preset algorithm, to obtain a curve comprising all of the location points; and determining an area in the curve as an area of interest. By using embodiments of the present application, areas of interest are automatically determined by using geolocation data accurately reported by users, thus avoiding low efficiency and high costs associated with having to manually demarcate areas of interest.
