use cases vignette
The rdwd
package provides a collection of all the metafiles on the DWD data server. It is presented as an interactive map below.
When a point is clicked, an infobox should appear. The first line can be copypasted into R to obtain more information on the available files. The map is created with the following code:
library(rdwd) ; data(geoIndex) ; library(leaflet)
leaflet(geoIndex) %>% addTiles() %>%
addCircles(~lon, ~lat, radius=900, stroke=F, color=~col)%>%
addCircleMarkers(~lon, ~lat, popup=~display, stroke=F, color=~col)
Open this vignette locally for faster map reaction times than on the CRAN html view:
The blue dots mark stations for which recent files are available (with >=1 file in ‘recent’ folder or ‘BIS_DATUM’ later than one year ago). The red dots mark all stations with only historical datasets.
To see only the stations with recent data, use the following code:
library(rdwd) ; data(geoIndex) ; library(leaflet)
leaflet(data=geoIndex[geoIndex$recentfile,]) %>% addTiles() %>%
addCircleMarkers(~lon, ~lat, popup=~display, stroke=F)
To request the nonpublic datasets counted in the infobox, please contact cdc.daten@dwd.de or klima.vertrieb@dwd.de. (The DWD cannot publish all datasets because of copyright restrictions).
Note: geoIndex
is created in the last section of rdwd-package.R.
