![]() It can be used for adding multiple map views, labels, legends, etc.Īs a free software application under GNU GPLv2, QGIS can be freely modified to perform different or more specialized tasks. In order to prepare printed map with QGIS, Print Layout is used. QGIS can display multiple layers containing different sources or depictions of sources. Several companies offer support and feature development services. As of 2012, developers have translated QGIS into 48 languages and the application is used internationally in academic and professional environments. QGIS is maintained by volunteer developers who regularly release updates and bug fixes. QGIS has a small install footprint on the host file system compared to commercial GISs and generally requires less RAM and processing power hence it can be used on older hardware or running simultaneously with other applications where CPU power may be limited. QGIS can also be used as a graphical user interface to GRASS. A mobile version of QGIS was under development for Android as of 2014. ![]() Īs of 2017, QGIS is available for multiple operating systems including Mac OS X, Linux, Unix, and Microsoft Windows. GDAL, GRASS GIS, PostGIS, and PostgreSQL are also recommended, as they provide access to additional data formats. In addition to Qt, required dependencies of QGIS include GEOS and SQLite. Written mainly in C++, QGIS makes extensive use of the Qt library. In 2013, along with release of version 2.0 the name was officially changed from Quantum GIS to QGIS to avoid confusion as both names had been used in parallel. Version 1.0 was released in January 2009. Gary Sherman began development of Quantum GIS in early 2002, and it became an incubator project of the Open Source Geospatial Foundation in 2007. QGIS can also be used with SAGA GIS and Kosmo. Plugins can geocode using the Google Geocoding API, perform geoprocessing functions similar to those of the standard tools found in ArcGIS, and interface with PostgreSQL/ PostGIS, SpatiaLite and MySQL databases. Plugins written in Python or C++ extend QGIS's capabilities. QGIS integrates with other open-source GIS packages, including PostGIS, GRASS GIS, and MapServer. Web services, including Web Map Service and Web Feature Service, are also supported to allow use of data from external sources. QGIS supports shapefiles, personal geodatabases, dxf, MapInfo, PostGIS, and other industry-standard formats. ![]() ![]() Multiple formats of raster images are supported, and the software can georeference images. Vector data is stored as either point, line, or polygon features. QGIS supports raster, vector and mesh layers. More advanced courses will be coming soon.QGIS functions as geographic information system (GIS) software, allowing users to analyze and edit spatial information, in addition to composing and exporting graphical maps. You should take this course if you need to learn the basics of QGIS quickly and if you'd like to sample QGIS before taking other courses. Do let me know if you have any suggestions for improvements as like to keep the course as up to date as possible. For some it's essential and I really want to make GIS accessible for all. For many participants this might seem quite basic. Please note that we do have ssome theory to get through first. The practical element is crucial and by all means try some new things out with the software. The course is structured as a mixture of lectures, quizzes and we'll end with a practical to put into practice all the knowledge you've gained. Explore the interface, ask quesstions, HAVE FUN! That said, playing around with the software is a great way to learn so don't worry if it takes you longer. It is a short course designed to get you started quickly. The course will take around 2 hours to complete. All sample data is original and provided for you. Starting at the beginner level we'll cover basic terminology and conventions, some of the fundamental principles of GIS, an overview of what QGIS is and then we'll get started with practical experience of using QGIS. This course is a complete introduction to GIS and QGIS.
