We recently opened up the BelgiumMaps.StatBel package and made it available at https://github.com/bnosac/BelgiumMaps.StatBel. This R package contains maps with administrative boundaries (national, regions, provinces, districts, municipalities, statistical sectors, agglomerations (200m)) of Belgium extracted from Open Data at Statistics Belgium.
The package is a data-only package where maps of administrative zones in Belgium are available in the WGS84 coordinate reference system. The data is available in several objects:
BE_ADMIN_SECTORS: a SpatialPolygonsDataFrame with polygons and data at the level of the statistical sector
BE_ADMIN_MUNTY: a SpatialPolygonsDataFrame with polygons and data at the level of the municipality
BE_ADMIN_DISTRICT: a SpatialPolygonsDataFrame with polygons and data at the level of the district
BE_ADMIN_PROVINCE: a SpatialPolygonsDataFrame with polygons and data at the level of the province
BE_ADMIN_REGION: a SpatialPolygonsDataFrame with polygons and data at the level of the region
BE_ADMIN_BELGIUM: a SpatialPolygonsDataFrame with polygons and data at the level of the whole of Belgium
BE_ADMIN_HIERARCHY: a data.frame with administrative hierarchy of Belgium
BE_ADMIN_AGGLOMERATIONS: a SpatialPolygonsDataFrame with polygons and data at the level of an agglomeration (200m)
The core data of the package contains administrative boundaries at the level of the statistical sector which can easily be plotted using the sp or the leaflet package.
library(BelgiumMaps.StatBel) data(BE_ADMIN_SECTORS) bxl <- subset(BE_ADMIN_SECTORS, TX_RGN_DESCR_NL %in% "Brussels Hoofdstedelijk Gewest") plot(bxl, main = "NIS sectors in Brussels")
All municipalities, districts, provinces, regions and country level boundaries are also directly available in the package.
data(BE_ADMIN_SECTORS) data(BE_ADMIN_MUNTY) data(BE_ADMIN_DISTRICT) data(BE_ADMIN_PROVINCE) data(BE_ADMIN_REGION) data(BE_ADMIN_BELGIUM) plot(BE_ADMIN_MUNTY, main = "Belgium municipalities/districts/provinces") plot(BE_ADMIN_DISTRICT, lwd = 2, add = TRUE) plot(BE_ADMIN_PROVINCE, lwd = 3, add = TRUE)
The package also integrates well with other public data from Statistics Belgium as it contains spatial identifiers (nis codes, nuts codes) which you can use to link to other datasets. The following R code example creates an interactive map displaying net taxable income by statistical code for Brussels.
If you are looking for mapping data about Belgium, you might also be interested in the BelgiumStatistics package (which can be found at https://github.com/weRbelgium/BelgiumStatistics) containing more general statistics about Belgium or the BelgiumMaps.OpenStreetMap package (https://github.com/weRbelgium/BelgiumMaps.OpenStreetMap) which contains geospatial data of Belgium regarding landuse, natural, places, points, railways, roads and waterways, extracted from OpenStreetMap
