GvSIG boasts the largest network of open-source integrated geomatics on the web. GIS Geography, a popular GIS publication, actually prefers gvSIG to QGIS for 3D mapping, calling it the best open-source 3D visualization tool available. GvSIG was developed in Valencia, Spain and released for public use in 2004. Army, it is still used today by agencies like NASA and the USDA. That said, for terrain analysis and geoprocessing, GRASS is difficult to beat. Though it's possible to create maps, users report the process is quite difficult and, given the availability of other more effective options, not worth the trouble. Primarily, an unintuitive user interface and clunky cartographic tools. Though aspects of GRASS are more developed that your average open-source GIS, it does have a few downsides.

Its code base is easy to inspect and manipulate, meaning it can be tailored to fit specific projects.įeaturing over 350 geoprocessing tools, GRASS specializes in raster and vector manipulation, but is also capable of image processing, graphic production, and data visualization.
GRASS GIS is a favorite in the academic community. This platform offers advanced geoprocessing tools and is used primarily for land management and environmental planning. GRASS stands for Geographic Resources Analysis Support System. Robust tools for raster and vector analysis.Land management and environmental planning.Though the cartographic functions within SAGA aren't particularly well developed, the unique geoscientific toolsets more than make up the difference. Despite the complexity of these processes, users report that the simple user interface makes these tasks relatively straightforward. With regression analysis and semi-variograms, users can engage in various predictive exercises. With powerful toolsets for raster processing, terrain analysis, and geoscientific data analysis - SAGA is a favorite among those working on more technical geoscience projects. It's capable of processing LiDAR data and offers 3D visualization - a relative rarity for open-source GIS. This platform specializes in geoscientific analysis. SAGA, System for Automated Geoscientific Analyses, is one of the best regarded GIS softwares on this list. Approachable user interface with many visualization options.A comprehensive, growing set of geoscientific methods.Easy and effective implementation of spatial algorithms.As an added bonus, users can view, edit, and analyze their geospatial data in both vector and raster format. QGIS gets high marks for its ability to automate map production, generate cartographic figures, and process geospatial data. QGIS can also integrate with other open-source GIS systems to extend its functionality.
The interface is fairly similar to ArcGIS, which allows experienced GIS users to jump in quickly and customize their tools and plugins. Use it for basic GIS tasks like map production and geospatial analysis, as well as more specific tasks like disaster risk reduction, terrain analysis, and environmental resource mapping.

QGIS is perhaps the only free GIS platform that’s effectively comparable to ArcGIS.

Though free GIS platforms don't offer full feature parity, many are still quite robust: capable of performing large a variety of geospatial mapping and analysis tasks.īelow, we cover the best free GIS mapping software available including ratings, features, mobile capabilities, and primary use cases. Open-source GIS software is a fantastic option for organizations on a budget or anyone looking to learn GIS without a huge financial commitment. New to GIS? Check out our beginner's guide to GIS These platforms tend to offer more updates and greater functionality, but the top tier options can be quite expensive. In contrast, commercial GIS involves a paid subscription or a one-time per user fee. That said, some open-source options are still quite powerful. In most case, free GIS software doesn't have the same functionality and support as commercial GIS. Open-source GIS software is free and the source code is openly available - meaning anyone can study it and/or make changes. GIS software comes in two general formats: open-source and commercial.
