Afforestation on topographic maps 1/20.000, Recording 1910-1940, 2021 update

This dataset shows the afforestation on the 3 rd edition of the topographic maps at 1:20.000 (1910-1940). Very suitable as a supplement to the forest age map or for specific research such as the localisation of deforestation. Use for detailed studies is not recommended unless for a field exploration. The 3 rd edition of the topographic maps shows geographical deviations. This map was selected for vectorisation of historical forests because automation was possible. As a source of information, the card has the disadvantage that it has been created over a long period of time as a result of WWI. East and West Flanders (including 1:50.000 numbers 15, 22, 30 and 38) were carved around 1910. The eastern half of Flanders was carved in the 1920s and 1930s. Some maps (19/7, 19/8, 20/5, 28/8 and 30/3) were not even re-triggered in the early 20th century and thus reflect the situation of around 1885.
