bd_topo_en.Rmd
The BD Topo database contains a 3D vectorial description, structured in objects, of the elements of the territory and its infrastructures, with a metric precision. The information available in BD Topo is grouped by themes guided by INSPIRE1 modeling:
The BD Topo database is produced by the Institut National de l’Information Géographique et Forestière (IGN), and is available at three levels of resolution: national, regional and departmental.
There have been several versions of the BD Topo database, the most recent being version 3.0. The history of the versions as well as the evolution of the product and the documentation can be consulted here: https://geoservices.ign.fr/sites/default/files/2021-07/SE_BDTOPO_avant_v3-0.pdf. This database is updated on a quarterly basis since 2019. The latest version of the database is available at the following address: https://geoservices.ign.fr/bdtopo. The entire documentation can be found in the address: https://geoservices.ign.fr/documentation/donnees/vecteur/bdtopo.
There are three formats available for the BD Topo database: - GeoPackage (Regions and departments) - Shapefile (Regions) - PostGreSQL (France and overseas territories)
floodam.data allows to manage the maintenance of an adapted database.
The key function used is :
There are 2 possible sources for downloading the database:
The last source is a mirror of the first one.
The download.bd_topo function downloads the database from the first address by default. However, the second address can be used by providing additional parameters (see function help: http://www.floodam.org/floodam.data/reference/download.bd_topo.html).
The scheme applied to the data depends on the chosen theme. The ‘building’ theme is the one of the global variable ‘floodam.data::scheme_bd_topo_3’, whose details are given in the following table.
