QGIS

A fully featured, user friendly, open source Geographic Information System (GIS) with similar power to ArcGIS and MapInfo.

• The GUI is pretty simple and intuitive and it runs decent on windows (at least as fast as ArcMap), but on GNU/Linux it flies. And since the license is GPL you can use it for different purposes (from educational to research or commercial) without worrying for a sue. Guest • May 2020 Disagree   Agree
• QGIS runs on multiple platforms, has a strong community and is becoming more and more mature. You can do almost everything using QGIS and it integrates very well with GRASS and SAGA for additional power. caiocco • Apr 2020 Disagree   Agree

• Closest in terms of UI, and gets a lot of extra power from integration with other packages like Grass and orfeo. Guest • Feb 2018 • 1 agrees and 1 disagrees Disagree   Agree
• QGIS can read geodatabases. The software is frequently updated and print composer is very good alternative to ArcGIS for map layouts. Guest • May 2017 • 4 agrees and 0 disagrees Disagree   Agree
• QGIS doesn't have the imagery tools, templates, or 3D capabilities of ArcGIS. Nor does it have the mobile apps and online cloud capabilities. Guest • Mar 2017 • 0 agrees and 10 disagrees Disagree   Agree

• Even though this programming language is not specific to spatial data, the vast collection of R packages available for importing, processing, analysing, converting and visualising spatial makes it an excellent alternative that can create fully reproducible processes. Searching "R Spatial" online will bring up a wealth of books, tutorials and resources. chtfn • Oct 2020 Disagree   Agree
