Abstract
The aim of this paper is to reveal, describe, explain, and map variations in diurnal population inthe metropolitan area of Prague. We use an alternative data source to traditional census-basedcartographic presentations and employ location data from mobile phones to identify types ofdaily rhythm that shape the region at different times during a typical weekday.
These rhythmsare influenced especially by residential and commercial suburbanization and the consequentdynamic development of new working centres, services, and leisure-time facilities within themetropolitan region. The main output consists of three maps.
Thefirst map contains atypology of the main functions-residential, work, transportation, and services-and is usedas the main analytical tool for sorting settlements, resulting in classification of nine types ofsettlement in all. The other two maps show a plastic image of the day- and night-timepopulations of the metropolitan area.
