1. Lesson: Een Korte Introductie

Welkom bij onze cursus! De komende dagen zullen we laten zien hoe u QGIS eenvoudig en efficient kunt gebruiken. Als GIS nieuw voor u is, dan vertellen we u wat u nodig heeft. Als een een ervaren GIS-gebruiker bent, dan zult u zien dat QGIS alle functies bevat welke u van een GIS verwacht, en meer!

In deze module introduceren we het QGIS project zelf, en wordt uitgelegd hoe de gebruikers-interface van QGIS in elkaar steekt.

Na afronding van deze sectie, kunt u de belangrijkste elementen in een QGIS scherm aanwijzen, en vertellen wat elke element doet, en een shape-bestand in QGIS laden.

Waarschuwing

Deze cursus bevat instructies voor het toevoegen, verwijderen en aanpassen van GIS datasets. We hebben hiervoor een test-dataset aangemaakt. Voordat u nu verder gaat, maak natuurlijk even een backup van uw eigen data.

1.1. Hoe gebruikt u deze handleiding

Any text that looks like this refers to something on the screen that you can click on.

Text that looks ‣ like ‣ this directs you through menus.

This kind of text refers to something you can type, such as a command, path, or file name.

1.2. Tiered course objectives

This course caters to different user experience levels. Depending on which category you consider yourself to be in, you can expect a different set of course outcomes. Each category contains information that is essential for the next one, so it’s important to do all exercises that are at or below your level of experience.

1.2.1. basic Basic

In this category, the course assumes that you have little or no prior experience with theoretical GIS knowledge or the operation of a GIS program.

Limited theoretical background will be provided to explain the purpose of an action you will be performing in the program, but the emphasis is on learning by doing.

When you complete the course, you will have a better concept of the possibilities of GIS, and how to harness their power via QGIS.

1.2.2. moderate Intermediate

In this category, it is assumed that you have working knowledge and experience of the everyday uses of GIS.

Following the instructions for the beginner level will provide you with familiar ground, as well as to make you aware of the cases where QGIS does things slightly differently from other software you may be used to. You will also learn how to use analysis functions in QGIS.

When you complete the course, you should be comfortable with using QGIS for all of the functions you usually need from a GIS for everyday use.

1.2.3. hard Advanced

In this category, the assumption is that you are experienced with GIS, have knowledge of and experience with spatial databases, using data on a remote server, perhaps writing scripts for analysis purposes, etc.

Following the instructions for the other two levels will familiarize you with the approach that the QGIS interface follows, and will ensure that you know how to access the basic functions that you need. You will also be shown how to make use of QGIS’ plugin system, database access system, and so on.

When you complete the course, you should be well-acquainted with the everyday operation of QGIS, as well as its more advanced functions.

1.3. Why QGIS?

As information becomes increasingly spatially aware, there is no shortage of tools able to fulfill some or all commonly used GIS functions. Why should anyone be using QGIS over some other GIS software package?

Here are only some of the reasons:

  • It’s free, as in lunch. Installing and using the QGIS program costs you a grand total of zero money. No initial fee, no recurring fee, nothing.
  • It’s free, as in liberty. If you need extra functionality in QGIS, you can do more than just hope it will be included in the next release. You can sponsor the development of a feature, or add it yourself if you are familiar with programming.
  • It’s constantly developing. Because anyone can add new features and improve on existing ones, QGIS never stagnates. The development of a new tool can happen as quickly as you need it to.
  • Extensive help and documentation is available. If you’re stuck with anything, you can turn to the extensive documentation, your fellow QGIS users, or even the developers.
  • Cross-platform. QGIS can be installed on MacOS, Windows and Linux.

Now that you know why you want to use QGIS, we can show you how. The first lesson will guide you in creating your first QGIS map.
