Examples

# Latest L-type DWD MOSMIX forecast file for Innsbruck Airport
url <- "https://opendata.dwd.de/weather/local_forecasts/mos/MOSMIX_L/single_stations/11120/kml/MOSMIX_L_LATEST_11120.kmz"

# Download and extract file
kmz   <- tempfile("mosmix_demo_", fileext = ".kmz")
check <- download.file(url, kmz)
if ( inherits(check, "try-error") ) stop("Problems downloading the file!")
kml   <- unzip(kmz)

# Parsing the unzipped kml file (XML format)
doc <- XML::xmlParse(kml)

# Extracting station information
# NOTE that, for this example, we are downloading the latest forecasts
# for one station (Innsbruck, 11120). Thus, the station information
# returned by get_station_information will also only contain this
# one station.
stations <- get_station_information(doc)
print(stations)
#>      coordinates  name          desc alt
#> 1 (11.35, 47.27) 11120 INNSBRUCK FL. 581

# Remove kmz and kml file
file.remove(kmz, kml)
#> [1] TRUE TRUE
