Automated extraction of map symbology from nineteenth century topographical maps by convolutional neural networks for understanding long-term changes in the extent and distribution of wetlands

Abbeyleix Bog in the Irish Midlands contains areas that were historically harvested for peat and then abandoned as well as areas that were never harvested. This study measured the carbon balance for both harvested locations and unharvested locations at Abbeyleix Bog. Measurements were conducted in the field over 2 years. This was carried out to understand how the historic harvesting and later abandonment of peat affect greenhouse gas emissions.
