Line 1: =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 [~~http~~https://www.qgis.org/ 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. [[Talk:QGIS_Tips \| 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.<br> If you are using QGIS as your model development or result viewing environment we strongly recommend installing the <u>[[TUFLOW_QGIS_Plugin\| TUFLOW QGIS Plugin]]</u>. It includes numerous tools to increase workflow efficiency. It also includes powerful result viewing functionality via its <u>[[TUFLOW_Viewer \| TUFLOW Viewer]]</u>.<br> <br> =Installation via OSGeo4W= QGIS can be installed through the OSGeo4W setup installer (Windows only). The benefit of this method is it allows the user to customise the installation, e.g. users can add additional Python libraries. It can also be subsequently run after the initial installation to upgrade QGIS to the latest version without the hassle of uninstalling the current version and then doing a full install of the latest version (the installer will only download and install relevant parts, overriding the current installation with the new version).<br> * <u>[[QGIS_Installation_with_OSGeo4W \| Installing QGIS via OSGeo4W steps]]</u><br> <br> =Basics= Line 10 ⟶ 18: # [[QGIS_Setting_Projection \| Setting Project Projection]] # [[QGIS_Shape_Editing \| Editing a Shapes Layer]] # [[~~QGIS_Table_Manager~~QGIS_Editing_Attributes \| Editing Attributes ~~with~~in ~~Table Manager Plugin~~QGIS]] # [[QGIS_Importing_a_Grid \| Importing a Grid]] # [[QGIS_Creating_a_Grid_from_Points \| Create a Grid From Points]] Line 17 ⟶ 25: =TUFLOW Viewer= TUFLOW Viewer is part of the QGIS TUFLOW plugin and used to view results of TUFLOW simulations in QGIS. <ol> *<li> [[TUFLOW_Viewer \| TUFLOW Viewer]] </ol> <br> Line 36 ⟶ 46: # [[QGIS_Nightly_(Dev)_Build \| Installation of QGIS Nightly Build]] # [[Troubleshooting_QGIS_Freeze_on_Start-up \| Troubleshooting QGIS Freeze on Start-up]] # [[QGIS_to_update_MapInfo_model \| Using QGIS to update an existing model originally built using MapInfo]] # [[QGIS_3D_Animations \| 3D Animations]] # [[QGIS_Create_a_TIN \| Create a TIN]] <br> =Useful QGIS plugins= Line 43 ⟶ 57: <li> [[TUFLOW_QGIS_Plugin#Error_While_Upgrading_Plugin \| Error While Upgrading Plugin]] </ol> <br> {{Tips Navigation \|uplink=[[Main_Page\| Back to Main Page]] }}
