The Restructuring and Cartographic Generalization of Digital River Data

This paper outlines an undertaking to introduce some structure to the drainage network data held by TIS, by the development of "rationalisation" and stream ordering software. As well as giving hydrographic and geographic benefits, the work cartographically facilitates the creation of computer generalised map products at a variety of scales, based on logical links in the restructured datasets. This aspect is illustrated from an area of S. W. England.
