Introduction
This page contains a brief introduction to the Quantum GIS software (QGIS). QGIS is a Free Open Source Software which for more information please see the QGIS website www.qgis.org/. The basics of QGIS, particularly with respect to TUFLOW modelling are described below, each of these has a separate page. If you have any suggestions to be included in these pages, please add them to the discussion page. Please add QGIS Suggestions Here!.
QGIS uses ArcGIS file formats for vector data, with data stored in shapefiles (.shp). QGIS, however, is able to read in MapInfo files directly. In the shapefiles, points, lines and regions are stored in separate files.
Basics
In this section are some basic GIS functions that are regularly used in creating TUFLOW models in QGIS.
- Webinar Link: QGIS Configuration and First Time User Tips for TUFLOW Modelling
- Generic QGIS New User Tutorials
- Setting Project Projection
- Editing a Shapes Layer
- Editing Attributes with Table Manager Plugin
