version 1.6.2
CRAN release: 2021-01-04
- [!] structure of administrative regions aligned to status as from January 2021 (Act 51/2020 Sb.)
version 1.6.1
CRAN release: 2020-10-30
union_sf removed entirely (after being deprecated in 1.6.0)
handling of remotely stored datasets amended to better align with the variety of PROJ versions supported
version 1.6.0
CRAN release: 2020-10-19
[!] all data objects now explicitly state the month for which the data is current
protected areas (chráněná území) based on AOPK open data instead of former ARC ČR500; the AOPK data are more current
small scale protected areas (maloplošná chráněná území) are included in output of chr_uzemi(); extra dimension to the dataset to differentiate small and large scale protected areas added. The downloaded file size increased to 7 MB.
dimension of ZUJ (základní územní jednotka) removed from obce datasets, in line with move to RÚIAN as main source of administrative units. RÚIAN does not support this metric, and it does not map easily to obce (a ZUJ is sometimes an obec, and sometimes a část).
union_sf() function is deprecated, as it has little connection to the Czech Republic; it is being moved to (so far experimental) package of spatial helper functions
dimensionality of ORP (obce s rozšířenou působností) was reduced - district / okres and shortened name were removed. This reflects the cardinality of dimensions - ORP do not map to okres 1:n, but m:n (several ORPs are spread over multiple districts, eg. Jihlava, Tanvald or Stod). Kraj was retained, as it maps 1:n (each ORP can be mapped to a single kraj).
