Solution Overview

Problem

Existing methods for determining areas of interest on maps based on geolocation data are inefficient and costly due to manual labor, leading to subjective errors in area demarcation.

Innovation Solution

A method and device that divide a map area into blocks, count terminal activity within each block, select anchor points based on threshold values, and use a convex hull algorithm to define an area of interest bounded by a curve encompassing these points, thereby automating the process.

AI summary

This application provides a method and a device for determining an area of interest based on geolocation data. The method includes: dividing an area on a map into a plurality of blocks; for each block in the area, determining the number of terminals within the block in a duration as a value of the block in the duration; determining a plurality of anchor points based on the blocks having values greater than a threshold; and obtaining a curve based on some or all of the anchor points, wherein an area bounded by the curve is an area of interest.
