| dc.description | This geospatial dataset was utilized for map production, statistics, and analyses in the Global Peatlands Assessment. Compiled by the Greifswald Mire Centre using data from the Global Peatland Database, the dataset exhibits the following characteristics: Geotiff in Projection: WGS 84; Values: 1 = peat dominated, 2 = peat in soil mosaic; Resolution: roughly 1x1 km.
The Global Peatland Map was compiled by amalgamating country-level peatland maps and high-resolution peatland ‘proxy’ data from the Global Peatland Database (GPD) using a ‘bottom-up approach’. The map is spatially explicit and presented in a 0.9 x 0.9 km raster, with varying levels of uncertainty depending on the region. The data primarily originates from scientific publications on soil and peatland research, as well from other ‘external’ sources such as national agencies and online repositories. We prioritized datasets that: 1. directly identified peatlands and clearly distinguished them from other land cover types (e.g., non-peatland wetlands), 2. had a large to mid spatial scale (1:25,000 to 1:250,000), and 3. provided comprehensive coverage of peatlands in the landscape unit.
The majority of the original publications consulted provide detailed information on the methods used and the uncertainties involved. All integrated data in this assessment adhere to the definitions outlined in the original studies.
