Contents Notes
This book explores in detail the practice and principles of contouring using a personal computer. Contouring allows a three dimensional view in two dimensions and thus is a fundamental technique to represent spatial data. All aspects of this type of representation are covered here including data preparation, selecting contour intervals, interpolation and griding, computing volumes and output and display. A set of twelve computer programs in BASIC is included with the book (on the diskette and also listed in the appendix). A compilation of published prgrams is appended along with a glossary and references to pertinent literature. Everything you want or need to know about contouring is included between these two covers. pt. 1. Practical Contouring. 1.0. Getting a Picture. 1.1. Data Preparation. 1.2.
