THE GRAPHIC REPRESENTATION OF POINT SURVEYED SURFACES BY THE USE OF A PLOTTER

ALCUNE APPLICAZIONE GRAFICHE AL PLOTTER PER RAPPRESENTAZIONI DI SUPERFICI RILEVATI PER PUNTI

Five computer programs for automatic contour mapping in topographic and highway applications, are described. Program PIAQUO enables the representation of all the relative points of the surveyed plane in such a way that the point position indicator on the design sheet corresponds to the decimal point of the spot measurements. Program SEMINA provides for the calculation of the height values of a surface in relation to the nodes of an orthogonal grid. Program CURLIV enables the automatic plotting of curves at prefixed heights from a matrix containing the spot measurements corresponding to the orthogonal grid covering the surface being contoured. Program ASSONO permits the isometric representation by plotter of the surface described by the points. Program PROSPE enables perceptive and three dimensional representation of surfaces and objects described by a set of points. /TRRL/
