Abstract : Two problem areas, referred to as Constrained Line Smoothing and Analytic Surface Modeling, have been studied carefully, solutions formulated, and FORTRAN software developed. In Constrained Line Smoothing, techniques are developed for efficient, smooth, constrained approximation of digitized lines (SMOOTH). In Analytic Surface Modeling, techniques are developed for modeling and contouring irregular topographic surfaces measured by UNAMACE data (SAPMAP). The SMOOTH and SAPMAP software have been tested on synthetic and real digitized data sets. The results, along with documentation for the formulations and software are presented. All software was written in FORTRAN 4 and all computation performed on a CDC 6400. (Author)
