README

Bestand Bodemgebruik 2017 (Land Use File)

Digital geometry of land use in the Netherlands (2017). Covers all functional land use at ground level: transportation, buildings, recreation, agriculture, forest, water. Uses a hierarchical classification with approximately 40 land use types. Boundaries largely based on Top10NL/BRT topographic map; aerial photographs from summer 2017 are the primary interpretation source. This is the BBG 2017 (old methodology); from 2020 onwards CBS produces the NBBG (renewed methodology). Published by CBS via PDOK.
