[edit] FOREWORD

"We will be showing you how to use QGIS easily and efficiently. If you are new to GIS, we will tell you what you need to get started. If you are an experienced user, you will see how QGIS fulfills all the functions you expect from a GIS program, and more!"

(Foreword, QGIS Training Manual)

[edit] INTRODUCTION

The aim of the QGIS Training Manual is:—

"...to provide all the materials needed to run a 5 day course on QGIS, PostgreSQL and PostGIS. The course is structured with content to suit novice, intermediate and advanced users alike and has many exercises complete with annotated answers throughout the text."

(ib.)

The objects of this particular article are:—

  1. To understand the basics of the QGIS user interface.
  2. To get started with an example map.
  3. Learn how to use Pan and Zoom tools within QGIS and learn about map scale.
  4. To be able to create any symbology you want for any vector layer.

It is therefore structured with content from Module 2 to suit novice users.
