Access Finnish Geospatial Data.
# install from CRAN
install.packages("geofi")
# Install development version from GitHub
remotes::install_github("ropengov/geofi")With geofi-package you can download geospatial data on
municipalities, zipcodes and population and statistical grids from
Statistics Finland WFS-api.
In addition, you have on-board municipality keys for aggregating
municipality-level data into higher level regional distributions based
Statistics Finland classification
API.
Below are few examples of the data you can access using
geofi. Please have a closer look at the vignettes
for more comprehensive use cases.
library(geofi)
d1 <- get_municipalities(year = 2023)
d2 <- get_zipcodes(year = 2023)
d3 <- get_statistical_grid(resolution = 5)
d4 <- get_population_grid(resolution = 5)

theme_minimal(base_family = "Arial") +
theme(legend.position= "none",
axis.text = element_blank(),

)
)
p1 <- ggplot(d1, aes(fill = kunta)) + geom_sf(colour = alpha("white", 1/3)) + labs(subtitle = "municipalities")
