Pros

  • QGIS GPL license offers freedom
  • Beautiful labeling options
  • Wide range of GIS analysis tools
  • Amazing data interoperability
  • Plugins extend functionality
  • Large user base and online support

Cons

  • Lack of 3D integration
  • Graphical modeller is buggy
  • Topology error fixing
  • Metadata standards

Cartography and symbology

The main advantage of QGIS 2 is its cartography, symbology and labeling. This is how it truly separates itself from others. QGIS mapping interface is ‘Print Composer’, which acts almost like a stand-alone application. Despite a lack of pre-existing symbols, it has loads of ways to customize cartography. For example, you can lighten, dodge and multiply symbols like Adobe Photoshop.

QGIS Plugins

Have no fear because the QGIS plugins are here. There are about 500 plugins available in the QGIS repository. As the number of plugins continues to grow, each one is as inventive as the next. Some of the most popular include network analysis, remote sensing classification and even Google Street view.

Data Management

QGIS Browser helps you easily navigate through your file system and manage geodata. For example, you can preview and examine tables for raster and vector formats. QGIS 3 does not have the QGIS Browser. But it’s still a great way to stay focused and pin down your GIS data sets.

Processing tools

QGIS has 500+ processing tools. This by itself is huge for analysis. But even better: There is tool integration with GRASS GIS and SAGA GIS. Both are open source software giving you capabilities in geosciences and geostatistics. Because of its flexibility, there’s no other open source GIS software that can give you this much horsepower.

Open Source

There are no license levels in QGIS because it’s completely open source. It’s built on the shoulders of the open source GIS community as volunteering developers stand by their product with pride. QGIS succeeds in a big way as one of the most complete mapping software options available to the GIS community.

Scripting and modeling

You can string a set of tools together using QGIS Graphical Modeler. Basically, you graphically develop sets of tools in a specified order. To say the least, it’s shaky at times. There is no QGIS module and you will be using GDAL a lot. You will also be using a bunch of other modules as needed for different projects. It can be difficult to figure out what to use and where it all is.

Rate of development

QGIS is making rapid strides forward. Despite relying on volunteer efforts, its support from the global community is unprecedented. Each version has improved since its debut in 2002. Alaskan Gary Sherman wrote the first code for it with all the basic pan, zoom and draw tools. QGIS 2 has ended in development and currently stands at version 2.18.

Interoperability

QGIS has a solid foundation for consuming data. By using the GDAL/OGR library, it can read and write over 70 vector formats. For table management, it’s superb with delimited columns. It can also handle rare types of files. For example, you can use NetCDF files for multidimensional scientific data.

Bend it in 3D

QGIS lacks decent 3D support. The Qgis2threejs plugin gives you primitive 3D mapping capabilities. It does this by exporting and projecting terrain data to your web browser. But if you want true 3D integration, then you should use QGIS 3. This is the newest and latest-greatest version of QGIS.

Summary

The best part about QGIS is that you require:

Zero budget.

Zero experience.

You can sit in the driver’s seat. Then, go into cruise control by making it your own.

Even though QGIS 3 is the newest version, QGIS 2 still gets a high grade as one of the top GIS software.

Development History

The speed of QGIS developing is stunning. Here are some highlights in its development:

  • In July 2002 Gary Sherman wrote the first version of QGIS 0.0.1. It only had basic tools like panning, zooming and drawing. Each release was a pet name with a splash screen.
  • In January 2009, Quantum GIS 1.0 was released. This version had capabilities to explore data, compose maps and publish maps on the internet.
  • In September 2013, QGIS 2.0 included a new vector API, geoprocessor, symbology and labelling overhaul.
  • On February 23, 2018, there was a milestone long-term release for QGIS 3.0. This release had 3D integration based on Qt5 and Python 3.

  1. I’m a moderately savvy computer user who is looking for a free software/app that will import and display an Excel list of addresses and display them as pins on a map. Will QGIS do this? Or is it complicated/overkill? If so, can you (or anyone) suggest something?

  2. This all sounds incredibly impressive – but utterly daunting. If I’m looking for a hobby mapping tool (for example (a) where have things come from and where did they end up or (b) a map of restaurants I’ve eaten in around the world) and I’m not very technologically savvy, will I be able to manage the jargon? Are there simpler alternatives for simple requirements?

  3. It might be worth updating the article “Search for OpenLayers Plugin in the plugin manager.”. This plugin is no longer available in the plugin manager. I wasted much time trying to find and install to no avail.

    See for example:

    “Don’t use the OpenLayers plugin – it’s very buggy. Use the QuickMapServices plugin instead.”

    “The OpenLayers Plugin is deprecate.”

    “It is recommended to use QuickMapServices or QGIS core functionality instead of OpenLayers Plugin because the latter has many issues.”

  4. We are a forestry company and have been using XMap 7 pro for our mapping projects. WE are looking for a product that can import our saved projects from XMap because XMap professional does not have an export feature. We also need the product to export projects so that we can share maps with other mapping formats. Does your product do either of these?

  5. Amazing QGIS. We use QGIS for all our mapping and analysis. This software has come a long way in the last couple of years and still keeps improving after each new version. The cartographic options are fantastic, even superior to one’s that you pay for. You get the power of GIS processing with GRASS integration. Impressed with QGIS. (QGIS 2.7)

  6. Started a new position where mapinfo was the software used and was able to hit the ground running due to qgis. It does everything I need faster adn easier than in map info without licencing costs or having to pay for extra capabilities. (QGIS 2.7)
