This plan covers part of East Staffordshire and its neighbouring counties. County borders are highlighted by coloured pecked lines. The large heath of Cannock Chase, once an expansive sweep of a great medieval royal hunting forest, is depicted at lower left. A section of the Ryknild Street is shown in buff down the middle of the sheet. This Roman road ran from the Fosse Way in Gloucestershire to Little Chester (Derby). Triangles used by Dawson to plot the survey are clearly visible outside the plan, with triangulations reported in a table at bottom right.
