Peat probability surface peat 5x5 m

This map indicates for the territory of Flanders, where peat is probably expected at the surface and where peat is probably not expected at the surface. This map gives a good picture of the spatial variation of peat and is a first estimate for where peat is present in Flanders with a high probability based on the best available data and techniques. The grid map is the result of applying the method from the study 'Veen in Flemish soil and subsurface in relation to climate and above- and underground use of space' (performed by KUL on behalf of DOMG) with the data collected in this study to calculate a 5x5 m peat probability map for the surface. The final report of this study can be found at: https://researchportal.be/en/publication/feather-Flemish-soil-and-under…. This grid map has been drawn up to provide more information about the local spatial variation of peat than is possible with the 50x50 m map from the KUL study. This makes this map more suitable to use at a local level and to determine where best to use peat protection. However, caution is still needed for local applications and especially for applications that require a very high level of security. For this, field verification is still recommended as a first step. The map is divided into two classes (probably peat/probably no peat) to simplify visualization and interpretation of the products. The study makes use of historical data (which can go back to the 19th century) as well as recent data from observations of peat. Certainly for the historical data, it is possible that the peat observed at the time is no longer present, which imposes limitations on the accuracy of the final result. During the creation of this map, no correction was made for known excavations (port docks, canals, ...), infrastructure in the subsurface (tunnels, cellars, ...) and watercourses. This allows the model to make erroneous predictions for these locations. This map, together with the peat probability map of the peat soil profile and the peat that situates visibility between 1.5 and 10 m deep, forms a set that is the result of the same recalculation exercise based on the results of the study conducted by KUL.
