| Description | The paper discusses the temporal mismatch between spatial representation and spatial data used in urban planning procedures. Majority of official statistical data, such as population census, only reflects the nighttime resident population. However, they are used as equivalent data to capture the 24-hour rhythm of the city and its inhabitants, and are often incorrectly attributed to the daytime. This temporal distortion can cause inaccuracies in planning processes and marginalise specific spatio-temporal issues by planners; analogous to how cartographic distortion affects the understanding of maps by their users. In order to comprehend temporal mismatch, we used nighttime aerial imagery of the city of Brno (CZE) and combined it with the most commonly used data in urban planning (population data, places of work and retail). Then we conducted relevant spatial tasks, such as spatial classification and delineation of functional zones within the city's nighttime chronotope and compared it with a commonly employed “daytime approach”. The most significant results are represented by a series of map comparisons to outline how the nighttime imagery can be beneficial for describing both dominant chronotopes of the city - nighttime and daytime. |
