Where2Test Saxony-Czechia COVID-19 new cases dataset

Data in the repository were used in the study "Fine-scale variation in the effect of national border on COVID-19 spread: A case study of the Saxon-Czech border region", published in Spatial and Spatio-temporal Epidemiology. This repository consists of two files: <strong>saxony-westczechia_cases7</strong> Weekly numbers of new COVID-19 cases in all municipalities in Saxony and Northwestern Czechia (Liberec, Ústí nad Labem, and Karlovy Vary regions) in the first half of 2021. Data are extracted from the websites coronavirus.sachsen and onemocneni-aktualne.mzcr.cz/covid-19. The missing values were interpolated, and daily values were recalculated to weekly values. <strong>municipalities</strong> The second file consists of a list of all municipalities with their names, geometries, and population values. For Germany, we used the dataset "Gemeindegrenzen 2018 mit Einwohnerzahl" (© GeoBasis-DE / BKG, Statistisches Bundesamt (Destatis) (2020), dl-de/by-2-0) as a source of geometries and population sizes of the municipalities (“<em>Gemeinde”</em>) in Saxony. Czech population numbers on the municipality level ("obec") were taken from the Czech Statistical Office, while the geometries were obtained from RÚIAN (@Czech Office for Surveying, Mapping and Cadastre, 2021). To keep the same geometry detail on both sides of the borders, we applied the Douglas-Peucker simplification algorithm implemented in the Python library TopoJSON.
