Abstract : A method for digitally constructing variable width cartographic lines, the invention provides an algorithm for generating symbolized lines using multiply-stroked centerline data. The algorithm allows generation of software which utilizes trigonometric functions and which can be implemented in applications using vector data with vector or raster plotters. The algorithm further accounts for basic cartographic principles, existing algorithm characteristics and hardware constraints imposed by specific output devices. (Author)
