Introduction

Overview

Surface modelling uses triangulation to create two-dimensional models known as digital terrain models (DTMs). This document introduces the theory behind surface modelling processes and provides detailed examples using the surface modelling functions in Surpac. By working through this tutorial, you will gain skills in the construction, use, and modification of DTMs.

Before you begin this tutorial, you must have:

• basic knowledge of Surpac

  It is recommended that you understand the procedures and concepts from the Introduction tutorial.

• Surpac v6.4, or later, installed on your computer
• the data set accompanying this tutorial
