hydroscoper is an R interface to the Greek National Data Bank for Hydrological and Meteorological Information, Hydroscope. For more details checkout the package’s website and the vignettes:

• An introduction to hydroscoper with details about the Hydroscope project and the package.
• Using hydroscoper’s data sets with a simple example of how to use the package’s internal data sets.

Install the stable release from CRAN with:

install.packages("hydroscoper")

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("ropensci/hydroscoper")

The functions that are provided by hydroscoper are:

• get_stations, get_timeseries, ..., etc. family functions, to retrieve tibbles with Hydroscope’s data for a given data source.
• get_data, to retrieve a tibble with time series’ values.
• hydro_coords, to convert Hydroscope’s points’ raw format to a tibble.
• hydro_translate to translate various terms and names from Greek to English.

The data sets that are provided by hydroscoper are:

• stations a tibble with stations’ data from Hydroscope.
• timeseries a tibble with time series’ data from Hydroscope.
• greece_borders a tibble with the borders of Greece.

This is a minimal example which shows how to get the station’s 200200 precipitation time series 56 from the kyy sub-domain.

Load libraries and get data:

library(hydroscoper)
library(tibble)
library(ggplot2)
ts_raw <- get_data(subdomain = "kyy", time_id = 56)
ts_raw

Let’s create a plot:

ggplot(data = ts_raw, aes(x = date, y = value))+
  geom_line()+
  labs(title= "30 min precipitation for station 200200",
       x="Date", y = "Rain height (mm)")+
  theme_classic()
