CONPLOT II - A Contour Generating Program.
Abstract
A contour generating system (CONPLOT II) is described whose input is a UNAMACE created magnetic tape. CONPLOT II is an improved and expanded version of CONPLOT I. Output of this sytem is a large cartographic quality contour map which can be combined to form still larger maps. This contour map includes (a) Universal Transverse Mercator Grin, (b) variable contour levels, (c) multiply labelled and broadened index contours, (d) depression indications, and (e) a variable output plotting scale. The following data handling techniques are used: (a) parallel processing, (b) random access, (c) binary searching, and (d) binary sorting. The internal processing of the input data includes (a) redundant data elimination, (b) noise elimination and data smoothing by either an Area Smoothing Algorithm or a Least Squares Smoothing Algorithm, (c) a contour smoothing algorithm, (d) fitting of resultant contours to streams to insure 'natural appearing' intersections, (e) fitting of resultant contours to roads to achieve right angle road/contour crossings, and (f) automatic mosaicking of multiple models into a single large plotted map.
