Afforestation on topographical maps 1/20,000, Recording 1910 - 1940, update 2021

This dataset shows the afforestation on the 3rd edition of the topographic maps at 1:20.000 (1910 - 1940). Very suitable as an addition to the forest age map or for specific research such as locating deforestation. The use for detailed studies is not recommended, except for terrain exploration. After all, the 3rd edition of the topographic maps show geographical deviations. This map was selected for vectorization of historical forests because automation was possible. As a source of information, the card has the disadvantage that it was created over a broad period as a result of WWI. East and West Flanders (including 1:50,000 numbers 15, 22, 30 and 38) were mapped around 1910. The eastern half of Flanders was mapped in the 1920s and 1930s. Some map sheets (19/7, 19/8, 20/5, 28/8 and 30/3) were not even re-carried out at the beginning of the 20th century and thus reflect the situation of around 1885.
