Hedges – National reference layer of hedges

## **BD HEDGE** ## National reference layer of linear hedges in metropolitan France The Haie DB is the result of the work initiated within the framework of the bocage monitoring system (DSB). The first version is the result of merging two data sources and their linearisation: hedges and groves of the vegetation theme of the topographical product of the IGN, called BD TOPO® and hedgerows with or without trees, aligned trees and groves from non-agricultural areas of the graphic parcel register (RPG). Since 2021, the linear repository of hedges has been set up as a base and integrated into the BDTOPO. Source: https://geoservices.ign.fr/bdhaie
