Differences between QGIS and ArcGIS: Comparative Analysis of the Two Leading Geographic Information Systems
In the realm of Geographic Information Systems (GIS), two popular software solutions stand out: QGIS and ArcGIS. Both offer a variety of features and functionalities, but they differ significantly in several aspects. Here's a breakdown of the key differences between these two GIS tools.
Cost and Licensing
One of the most prominent differences lies in the cost and licensing. QGIS is a free and open-source software, released under an open-source license, making it highly accessible worldwide. On the other hand, ArcGIS requires purchasing licenses, which can make it more costly and restrict its use mostly to organizations that can afford it.
Operating System Compatibility
When it comes to operating system compatibility, QGIS is the more versatile option. It supports Windows, macOS, Linux, and BSD, and soon Android. ArcGIS Pro, however, is limited to Windows (with no native macOS support), which can be a constraint for Mac users.
File & Geodata Support
Both software support numerous file types and geospatial data formats, but QGIS emphasizes open standards and interoperability. While ArcGIS has powerful proprietary formats like the Esri Geodatabase and strong cloud integration with ArcGIS Online, QGIS is known for its emphasis on open standards and interoperability.
Source Code and Extensibility
QGIS's open-source nature allows users and developers to inspect, modify, and extend the code, fostering a rich plugin ecosystem. ArcGIS offers extensions and SDKs but its core software is closed-source.
Mapping and Analysis Features
ArcGIS Pro is known for advanced spatial analytics, 3D capabilities, and high-end cartographic tools, including integration with CityEngine for urban modeling. QGIS covers most standard GIS functionalities well and integrates with tools like Blender for 3D visualization but is generally considered less advanced in certain spatial modeling features.
User Support and Documentation
ArcGIS benefits from extensive official documentation, tutorials, and professional support from Esri. QGIS relies on a community-driven documentation approach alongside active user forums.
Data Entry and Tools
ArcGIS offers sophisticated data editing environments. QGIS provides various tools and plugins for data capture and manipulation but with fewer native advanced editing features.
Performance
ArcGIS is generally optimized for large datasets and complex workflows, whereas QGIS performance is good but may lag with very large enterprise projects.
Future Development
QGIS features frequent community-driven updates and improvements, often rapid and responsive to user input. Esri follows a planned development schedule with major releases enhancing ArcGIS’s capabilities systematically.
In summary, QGIS excels in cost-efficiency, platform flexibility, and open-source accessibility, making it ideal for users needing a versatile, free GIS tool. ArcGIS offers more advanced, high-performance features, comprehensive vendor support, and industry-standard tools but at a higher cost and with less operating system flexibility. The choice depends heavily on user needs, budget, and platform preferences.
Additional features of ArcGIS include the Maplex marking motor for advanced mapping functionalities, allowing various information edges to be included and connected. However, ArcGIS requires a paid license, which can be costly and may restrict access after leaving an organization. QGIS is based on PostGIS for data storage, which works well with large data files. Both software enable easy navigation to deal with the geodata in your file system.

- While QGIS is a free and open-source software, ArcGIS requires purchasing licenses, which can make QGIS more accessible in terms of cost to a broader user base.
- QGIS supports a wider range of operating systems compared to ArcGIS, being available on Windows, macOS, Linux, BSD, and soon Android, whereas ArcGIS Pro is largely limited to Windows.
