QGIS is a free, open-source, cross platform geographical information system

Summary

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 Support for raster, vector, mesh, and point cloud data in a range of industry-standard formats Raster formats include: GeoPackage, GeoTIFF, GRASS, ArcInfo binary and ASCII grids, ERDAS Imagine SDTS, WMS, WCS, PostgreSQL/PostGIS, and other GDAL supported formats. Vector formats include: GeoPackage, ESRI shapefiles, GRASS, SpatiaLite, PostgreSQL/PostGIS, MSSQL, Oracle, WFS, Vector Tiles and other OGR supported formats. Mesh formats include: NetCDF, GRIB, 2DM, and other MDAL supported formats. Point-cloud format: LAS/LAZ and EPT datasets. Data abstraction framework, with local files, spatial databases (PostGIS, SpatiaLite, SQL Server, Oracle, SAP HANA), and web services (WMS, WCS, WFS, ArcGIS REST) all accessed through a unified data model and browser interface, and as flexible layers in user-created projects Spatial data creation via visual and numerical digitizing and editing, as well as georeferencing of raster and vector data On-the-fly reprojection between coordinate reference systems (CRS) Nominatim (OpenStreetMap) geocoder access Temporal support Example: Temporal animation Example: 3D map view 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 Ge...
