The map shows the locations and names of the sites of the topographic, peat depth and reconnaissance surveys carried out for the Scottish Peat Committee, latterly based at the Macaulay Institute for Soil Research (MISR). These surveys mainly comprise raised bogs and peat workings and include the surface and bottom contours, peat depth, isopachytes, cross-sections, peat volume, and peat quality. The surveys are listed here.

When zoomed in to a scale of 1:250,000, the outlines of the 1:250,000 soil map units are displayed and their soil map unit code, as well as the name of the peat survey site and a point indicative of its location. If available details are also provided of the area of peat (greater than 1.5 m deep), volume of peat (in areas greater than 1.5 m deep), and the maximum peat depth measured at the site. For details of the 1:250,000 soil map units please go to the Scotland’s Soil website.
