QGIS 3.16: The Latest and Greatest in Open Source GIS Technology


Introduction




QGIS is a free and open source geographic information system (GIS) that allows you to create, edit, visualize, analyze and publish geospatial data. QGIS is developed by a community of volunteers and professionals who are passionate about GIS and spatial data. QGIS is compatible with many operating systems, including Windows, macOS, Linux, Android and iOS. QGIS also provides web applications, a spatial file browser, and a server application.


QGIS is a powerful and versatile tool for working with spatial data. You can use QGIS to explore data and compose maps, create and edit vector and raster layers, perform spatial analysis and geoprocessing, publish maps on the web, and extend QGIS functionality through plugins. QGIS supports many formats and standards, such as OGC web services, GDAL/OGR libraries, GeoPackage, Shapefile, GeoTIFF, PostGIS, SpatiaLite, GRASS GIS, OpenStreetMap and more.

In this article, I will show you how to download and install QGIS 3 16, the latest stable version of QGIS, on your computer. QGIS 3 16 was released on October 23rd 2020 and is codenamed 'Hannover'. It comes with many new features and improvements, such as temporal support for raster and vector data, 3D map view enhancements, mesh layer editing capabilities, new processing algorithms and providers, improved user interface and usability, bug fixes and performance optimizations.


QGIS features




QGIS offers a wealth of GIS functions, provided by core features and plugins. Here are some of the main features of QGIS:


  • View data: You can view combinations of vector, raster and mesh data in 2D or 3D in different formats and projections without conversion to an internal or common format. You can also view online spatial data served as OGC web services.



  • Explore data and compose maps: You can compose maps and interactively explore spatial data with a user-friendly GUI. You can use tools such as the locator bar, on-the-fly reprojection, DB Manager, print layout, report builder, overview panel, spatial bookmarks, annotation tools, identify/select features, edit/view/search attributes, data-defined labeling and symbology.



  • Create, edit, manage and export data: You can create, edit, manage and export vector and raster layers in several formats. You can use tools such as vector digitizing tools, georeferencer tool to geocode vectors and images, GPS tools to import/export GPX format or connect to a GPS device directly (on Linux), support for visualizing and editing OpenStreetMap data.



  • Analyze data: You can perform spatial analysis and geoprocessing using various tools such as vector analysis tools (e.g., buffer), raster analysis tools (e.g., slope), sampling tools (e.g., random points), geometry tools (e.g., centroid), database management tools (e.g., join attributes by location), GRASS GIS integration with more than 400 modules available.



  • Publish maps on the web: You can publish your QGIS projects and layers as OGC compatible web services such as WMS (Web Map Service), WMTS (Web Map Tile Service), WCS (Web Coverage Service), WFS (Web Feature Service) or WFS-T (Web Feature Service Transactional) using the QGIS Server application. You can also use the QGIS Web Client or other third-party web applications to display your maps on the web.

In addition to the operating system, you also need to have enough disk space, memory and processing power to run QGIS smoothly. The exact amount of resources needed depends on the size and complexity of your data and projects, but here are some general guidelines:



  • Disk space: You need at least 500 MB of free disk space to install QGIS, plus additional space for your data and plugins.



  • Memory: You need at least 4 GB of RAM to run QGIS, but more is recommended for better performance and stability.



  • Processing power: You need at least a dual-core processor to run QGIS, but a quad-core processor or higher is recommended for faster processing and rendering.



  • Graphics card: You need a graphics card that supports OpenGL 2.0 or higher to run QGIS, but a dedicated graphics card with more memory and features is recommended for better visualization and 3D support.



  • Internet connection: You need an internet connection to download QGIS and access online data sources and services.



QGIS download options




To download QGIS 3 16, you have several options depending on your platform and preferences. Here are the main download options for QGIS 3 16:



  • Standalone installer: This is the easiest and most common way to install QGIS on Windows and macOS. It provides a single executable file that contains all the necessary components and dependencies for QGIS. You can choose between the long term release (LTR) version, which is more stable and supported, or the latest release version, which has more features and updates. You can also choose between the network installer, which downloads the files during installation, or the offline installer, which includes all the files in a single package.



  • OSGeo4W installer: This is an alternative way to install QGIS on Windows. It provides a package manager that allows you to install QGIS along with other open source geospatial software such as GDAL, GRASS GIS, SAGA GIS, etc. You can choose between different versions and configurations of QGIS, as well as other packages and libraries that you may need.



  • Docker image: This is a way to run QGIS on any platform that supports Docker, such as Linux, Windows or macOS. Docker is a software that allows you to create and run virtual containers that isolate applications from the host system. You can use the official QGIS Docker image to run QGIS without installing it on your computer.



  • Snap package: This is a way to install QGIS on Linux systems that support snap packages, such as Ubuntu. Snap packages are self-contained applications that can be installed and updated easily from the snap store. You can use the official QGIS snap package to install QGIS on your Linux system.



  • Apt repository: This is a way to install QGIS on Debian-based Linux systems such as Ubuntu using the apt package manager. You can add the official QGIS apt repository to your sources list and install QGIS using the apt command.



  • RPM repository: This is a way to install QGIS on RPM-based Linux systems such as Fedora or CentOS using the RPM package manager. You can add the official QGIS RPM repository to your sources list and install QGIS using the yum or dnf command.



  • Homebrew package: This is a way to install QGIS on macOS systems that support Homebrew, a popular package manager for macOS. You can use the Homebrew command to install QGIS and its dependencies from the Homebrew repository.



  • Android package: This is a way to install QGIS on Android devices such as smartphones or tablets. You can download and install the QGIS Android package (APK) from the official QGIS website or from the Google Play Store.



  • iOS package: This is a way to install QGIS on iOS devices such as iPhones or iPads. You can download and install the QGIS iOS package (IPA) from the official QGIS website or from the App Store.
