Drawing lines on maps: morphological regions and planning practices

Abstract

The delimitation of morphological regions is a fundamental research activity, particularly for those urban morphologists with geographical backgrounds. Delimitations reflect the origin, development and modification of the urban forms being considered and the different methods of delimitation employed. Clear rationales for the decisions on precisely where to draw boundary lines are sometimes lacking. This paper explores regions and boundaries, drawing upon evidence from a range of studies using detailed measurements derived from digital mapping to assist discussion of differences within and between areas. It also reviews applications of such boundarydrawing processes to contemporary planning issues, including ‘character areas’ and conservation, using work undertaken for local planning authorities in the English Midlands.
