The actual workflow is explained in method for access analytics. This access analytics map is about the entire access to Digital Typhoon. This heatmap is visualized for the access count of spatio-temporal grid of 1 degree and 1 hour, transformed into a logagrithm scale. The access count is computed for the number of different IP addresses in a spatio-temporal grid, and the occurrence of IP addresses to any files (not only page views but also any other files) is counted for each grid. However, it is counted once even if multiple users with the same IP address visit the site multiple times. The color is set to red if 1000 IP addresses are found.
