alboFr

The goal of alboFr is to retrieve the latest online data from https://signalement-moustique.anses.fr/signalement_albopictus/colonisees and convert them into an sf object.

Installation

You can install the development version of alboFr from R-universe with:

install.packages("alboFr",
  repos = c("https://e-kotov.r-universe.dev",
    "https://cloud.r-project.org"
  )
)

You can also install the development version of alboFr from GitHub with:

# install.packages("pak")
pak::pak("e-kotov/alboFr")

Example with sf data type

The package only has one function to get the data:

library(alboFr)

x_sf <- get_tiger_mosquito_colonisation_in_france(output = "sf")

head(x_sf)

Simple feature collection with 6 features and 1 field
Geometry type: POLYGON
Dimension:     XY
Bounding box:  xmin: 1.195249 ymin: 42.99451 xmax: 7.835923 ymax: 48.64427
Geodetic CRS:  WGS 84
  toujours_signaler                       geometry
1              TRUE POLYGON ((7.77076 48.49202,...
2              TRUE POLYGON ((1.987127 42.99451...
3              TRUE POLYGON ((1.584032 44.76673...
4              TRUE POLYGON ((1.249545 44.34751...
5              TRUE POLYGON ((2.566791 43.02245...
6              TRUE POLYGON ((3.502814 43.97531...

The data can then be plotted:

library(ggplot2)
p <- ggplot(x_sf) +
  geom_sf(aes(fill = toujours_signaler), col = NA) +
  facet_wrap(~toujours_signaler)
p
# ggsave(
#   filename = "man/figures/map.png",
#   plot = p,
#   width = 5,
#   height = 4,
#   units = "in",
#   dpi = 300
# )

Finally the data can be saved to a GeoPackage file:

library(sf)
st_write(x_sf, "tiger_mosquito_colonisation_in_france.gpkg")

Example without sf data type

You do not have to have sf package installed to use {alboFr}. You can just retrieve the data in geojson format and save it directly to disk bypassing the sf object creation:

x_geojson <- get_tiger_mosquito_colonisation_in_france(output = "geojson")
writeLines(x_geojson, "tiger_mosquito_colonisation_in_france.geojson")

Data license

The original data does not have a well defined license, but the legal matters regarding this data can be found here: https://signalement-moustique.anses.fr/signalement_albopictus/mentionslegales.

Data archive

The data provider does not supply data versioning, but you can find the daily automatic snapshots of the data in this GitHub repository https://github.com/e-kotov/alboFr-data-archive or at Zenodo https://doi.org/10.5281/zenodo.14914293.
