This vignette illustrates the use of openairmaps to produce a simple interactive leaflet maps showing weather station sites.

Network map

The simplest function is simply to create a network map with the network_map function shown below

here::i_am("vignettes/openairmaps.Rmd")
library(metamet)

fname_site <- here::here("data-raw/dt_site.csv")
dt_site <- fread(fname_site)
network_map(dt_site)

Polar plot maps

We can also create interactive polar plot maps using polar_map(). The function extracts the appropriate time, wind speed, and wind direction fields from a metamet object, and produces a leaflet-based polar map. for a varible var_name chosen to be mapped.

fname_dt <- here::here("data-raw/UK-AMO/UK-AMO_BM_dt_2026.csv")
  fname_meta <- here::here("data-raw/dt_meta.xlsx")
  fname_site <- here::here("data-raw/dt_site.csv")
  # half-hourly data
  mm <- metamet(
    dt = fname_dt,
    dt_meta = fname_meta,
    dt_site = fname_site,
    site_id = "UK-AMO"
  )
  polar_map(mm, var_name = "PA_4_1_1")
