Module M09 - Participatory Scale Mapping and Surveying

Unit M09U01 - Introduction to Scale Maps and Basic Cartography

Introduction

This Unit introduces scale maps and the basic principles of cartography or map drawing. It explains how maps are made, describes the basic elements seen on all scale maps and demonstrates how to read maps. Standard mapping conventions are used to make credible scale maps and these conventions are described in the principles of cartography.

Practical tools are taught, such as how to measure distance using scale, how to find a location using the map grid and how to read the pattern of the land in the contour lines of a topographic map. These are essential skills for making scale maps.

Unit objectives / expected outcomes

After completion of the Unit the trainee will be able to:

  • describe basic features of scale maps;
  • list the basic elements of a scale map;
  • explain the objective of symbols and legends on scale maps;
  • name two main types of maps and their use;
  • specify the use of topographic maps;
  • describe the characteristics of contour lines;
  • work with scales;
  • explain the orientation or direction on a map and the effect of magnetic declination;
  • describe two common coordinate systems of a map grid;
  • specify the meaning of projections and datums;
  • discuss strengths and limitations of scale maps.
