QGIS

QGIS is a full-featured, user-friendly, free-and-open-source (FOSS) geographical information system (GIS) that runs on Unix platforms, Windows, and MacOS. Features 1. Flexible and powerful spatial data management 2. Beautiful cartography 3. Advanced and robust geospatial analysis 4. Powerful customization and extensibility 5. QGIS Server Under the hood Versions and release cycle Free and Open Source Installing and using QGIS Documentation Help and support channels Get involved with the community 2. Beautiful cartography Large variety of rendering options in 2D and 3D Fine control over symbology, labeling, legends and additional graphical elements for beautifully rendered maps Respect for embedded styling in many spatial data sources (e.g. KML and TAB files, Mapbox-GL styled vector tiles) In particular, near-complete replication (and significant extension) of symbology options that are available in proprietary software by ESRI Advanced styling using data-defined overrides, blending modes, and draw effects 500+ built-in color ramps (cpt-city, ColorBrewer, etc.) Create and update maps with specified scale, extent, style, and decorations via saved layouts Generate multiple maps (and reports) automatically using QGIS Atlas and QGIS Reports Display and export elevation profile plots with flexible symbology Flexible output direct to printer, or as image (raster), PDF, or SVG for further customization On-the-fly rendering enhancements using geometry generators (e.g. create and style new geometries from existing features) Preview modes for inclusive map making (e.g. monochrome, color blindness) For more maps created with QGIS, visit the following pages: Amazing maps created using QGIS Map Gallery on QGIS Hub QGIS Map Showcase Flickr Group. 3. Advanced and robust geospatial analysis Powerful processing framework with 200+ native processing algorithms Access to 1000+ processing algorithms via providers such as GDAL, SAGA, GRASS, OrfeoToolbox, as well as custom models and processing scripts Geospatial database engine (filters, joins, relations, forms, etc.), as close to datasource- and format-independent as possible Immediate visualization of geospatial query and geoprocessing results Model designer and batch processing 4. Powerful customization and extensibility Fully customizable user experience, including user interface and application settings that cater to power-users and beginners alike Rich expression engine for maximum flexibility in visualization and processing Broad and varied plugin ecosystem that includes data connectors, digitizing aids, advanced analysis and charting tools, in-the-field data capture, conversion of ESRI style files, etc. Style manager for creating, storing, and managing styles QGIS style hub for easy sharing of styles Python and C++ API for standalone (headless) applications as well as in-application comprehensive scripting (PyQGIS) Headless map server -- running on Linux, macOS, Windows, or in a docker container -- that shares the same code base as QGIS. Industry-standard protocols (WMS, WFS, WFS3/OGC API for Features and WCS) allow plug-n-play with any software stack Works with any web server (Apache, nginx, etc) or standalone All beautiful QGIS cartography is supported with best-in-class support for printing Fully customizable with Python scripting support QGIS development and releases follow a time based schedule/roadmap. There are three main branches of QGIS that users can install. These are the Long Term Release (LTR) branch, the Latest Release (LR) branch, and the Development (Nightly) branch.
