本数据集为2019年1月以来通过网络爬虫技术获得的全国Flickr用户逐月活跃量的网格化矢量数据，共12期。经数据聚合等预处理，每个网格单元上记录该区域每月Flickr用户发布带地理坐标图片的数量，反映用户在区域的到访足迹强度。数据格式为Shapefile格式，空间单元为1°大小的网格单元。

This dataset consists of gridded vector data on the monthly activity volume of national Flickr users obtained via web crawling technology since January 2019, with a total of 12 periods. After preprocessing such as data aggregation, each grid cell records the number of geotagged photos posted by Flickr users in the area each month, reflecting the intensity of users' visit footprints in the region. The data format is Shapefile, and the spatial unit is 1°×1° grid cells.
