-
dependency on {raster} replaced by newer {terra} package
-
fixes incorrect behavior of Vltava in Prague
-
internal optimization in line with updated dependencies
-
updated stale links in documentation

- internal optimization, minor bugfixes
- resubmission after archival due to issues with macOS 12 (Monterey)
- the reky (rivers) function gained optional parameter resolution, allowing usage of smoother low res object
-
[!] waterways (rivers and water bodies) and transport networks (roads and railroads) are based on Data200 from ČÚZK instead of earlier (and by now somewhat dated) ArcČR 500 v3.3 from ARCDATA.
-
vignette updated to use static election result (via the Wayback Machine) instead of raw volby.cz
-
minimal supported versions of GDAL, GEOS and PROJ explicitly specified (PROJ being the most relevant)
-
structures aligned with upcoming sf / s2 release
-
internal bump to latest valid RÚIAN data (June 2021)
-
[!] result of geocode() is now standardized; the function is now guaranteed to return a sf data frame
-
[!] naming of the special sf geometry column is standardized to
geometryin all cases; this reverses changes introduced in v1.5.0 with move to RÚIAN data source
- internal improvements in handling of (temporarily) unavailable internet resources
-
volebni_okrsky(), senat_obvody() and zip_codes() functions added, based on helpful suggestions from Jakub Komárek
-
resolves invalid geometries of okresy, orp_polygony and chr_uzemi
-
resolved inconsistencies in geometries of okresy Brno město & Brno venkov
-
updated vignette ({czso} replaces downloaded csv files; viz of Senát added)
-
unit tests adjusted to decrease load on CRAN servers
- resolves issues with version 1.6.2 on systems with PROJ under 6.0.0
- [!] structure of administrative regions aligned to status as from January 2021 (Act 51/2020 Sb.)
-
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
-
[!] 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).
-
bugfix in simplified shapefiles / kraje("low")
-
unit tests updated
-
url of vanity badges changed to https
- minor correction of simplified shapefiles (low res objects)
-
[!] administrative areas based on RÚIAN generalized boundaries instead of former ARC ČR500; this results in a negligible loss of accuracy, and a significant reduction of size (and download time)
-
special cases of rivers object implemented for easier visualization of Prague and Brno maps
-
unit tests reflect recent changes in PROJ
- dependency on lwgeom decommissioned (st_make_valid moved to sf)
-
tidyverse style guide applied
-
examples updated to resolve warnings
-
bug in union_sf() corrected
-
vyskopis() function added to facilitate rasters of Czech relief; dependency on {raster} introduced
-
dependency on {sf} changed from Imports to Depends (loading of RCzechia triggers a load of sf)
-
dependency on {tmap} decommissioned, vignette refactored to {ggplot2} & {leaflet} only
-
KFME grid cells (faunistické čtverce) object added
-
minor optimization of geocode() and tests
-
downgraded error on unavailable internet to message in line with updates to CRAN policy
-
internal optimization
-
introduced geocode and revgeo functions (via ČÚZK API)
-
optimization of documentation and vignette
- upgraded shapefile downloads from http:// to https://
- updated vignette (Czech Population) to reflect changes in readxl package

-
unit tests optimized

-
internet connection not required for using lo-res shapefiles
-
dependency on tidyverse replaced by dplyr

[!] this is the the first CRAN version
-
[!] to make the package pass CRAN size requirements data files were changed from internal to external (internet connection required to load)
-
a development version is available on https://github.com/jlacko/RCzechia
