BD Bocage PNR Normandie-Maine

The Bocage PNR Normandie-Maine comic book is a database of hedges digitised throughout the territory of the Parc & Géoparc (perimeter classified as charter 2008-2023), with several vintages (1945, 2000, 2010 and 2020), differentiating the types of hedges (live hedge with a dominant high jet, without a dominant high jet, low hedge, tree alignment, and bare slopes), and according to a specification common to the Norman PNR. The digitization work was carried out by photo-interpretation (PIAO) at 1/5000, first version in 2014 by a first design office, then updated in 2022 by a second. The years of the IGN aerial photographs used vary slightly by department. Handle: 1947 | 2002 | 2010 | 2019. Mayenne: 1950 | 2001 | 2010 | 2019. Orne: 1947 | 2001 | 2010 | 2020.
