This map corresponds to the "Carte topographique et hypsométrique de Bruxelles et ses environs", drawn around 1858 at a scale of 1:20,000 by Joseph Huvenne (draftsman, topographer) and engraved by J. Ongers. It covers the Brussels region from Neder-Over-Heembeek to Drogenbos and from Berchem-Sainte-Agathe to Auderghem.

This dataset corresponds to the macrozone dataset, i.e. the highest-level statistical partition of the Brussels-Capital Region (the Region is divided into 17 macrozones).

This dataset includes the urban planning infractions observed on the territory of the city of Brussels as specified in article 300 of the Code bruxellois de l'aménagement du territoire / Brusselse wetboek van Ruimetelijke ordening.
