GEOPLOT: um sistema gráfico para representações de modelos digitais de terrenos

Abstract

This paper presents a graphics system, designated GEOPLOT, developed to display digital terrain models graphically. GEOPLOT is a set of TURBO PASCAL programs for IBM-PC compatible microcomputers. These programs allow one to obtain a map of a data points, the convex hull of a set of data points, and the interpolation of a the digital model and its graphical displays (i.e. contour map and perspective plot). This system also contains a computer program that retrieves the plotting files from display programs and puts out high quality drawings directly on standart dot printers. Finally GEPLOT graphics system provides graphlcal dlsplays of digital terrain models rapidly, with accuracy and versatility.
