There are two basic categories of GIS software: commercial and open-source.
Commercial GIS software involves a paid license of some kind, either through subscription or a one-time perpetual license. Open-source GIS software is free for anyone to use.
Within these broad categories, there are many individual software options: each with significant variation in terms of functionality, price point, and ease-of-use.
When choosing a GIS software, first decide between commerical and open-source.
Learn the basics of GIS with part one: What is GIS?
Commercial GIS software tends to have more capabilities and better support, but can be quite pricey.
Open-source software has the distinct advantage of being free, but often has less functionality.
Next, consider where, how, and by whom the platform will be used. The answers to those questions will help determine software type (desktop, online, or mobile) will be most effective.
In this chapter, we’ll cover the different types of GIS software, as well as the most popular commercial and open-source GIS platforms available.
GIS software comes in three main formats: desktop, online/cloud, and mobile.
Many platforms are only available in one format, while others allow for a combination.
For example, a legacy GIS software such as ESRI, offers both desktop and online options. However, each product must be purchased separately.
Below we’ll explore the advantages and disadvantages of between desktop, mobile, and online GIS.
Desktop GIS software is installed directly onto a desktop or laptop computer. The program will only run on that computer and all data is stored on a local hard drive.
In terms of functionality, desktop GIS tends to be more robust. For organizations doing geo-scientific research, complex spatial analysis, and 3D rendering - these platforms are an attractive option.
Online GIS is most frequently run on cloud servers: eliminating the need for installation and local data storage.
With cloud-based GIS platforms, users can make updates in real-time, access data from anywhere, and share information quickly.
Most online GIS platforms operate on a monthly or yearly subscription basis. This stands in contrast to desktop platforms, which are more expensive upfront, but only require a one-time payment.
Mobile GIS is, in many ways, a subcategory of online GIS. Most mobile devices don’t have the processing power necessary to run a GIS software locally, and so rely on cloud-based mobile applications.
Some GIS softwares offer mobile functionality as a built-in feature, while others require additional purchase of a separate mobile program.
Theoretically, mobile GIS can run on any mobile device; however, device cross-functionality ultimately depends on which platform you choose.
Commercial GIS softwares require a subscription or a one-time perpetual license. They can be divided into two categories: desktop and online.
Desktop GIS platforms tend to have the broadest, most powerful feature suites.
Look to these programs for complex spatial analysis, 3D rendering, and advanced map making.
Keep in mind - with that advanced functionality, comes the steepest learning curve and highest price tag.
In this section, we cover five of the most popular desktop commercial GIS software options.
Each of the platforms below involves a one-time perpetual license fee and must be installed onto a specific computer.

Moreover, built-in quality assurance tools ensure that all network data is consistent throughout the entire organization.
Name: OpenCities Map
Price: Not available online
Best for: Data management for organizations that map, plan, design, build, and operate operations, and maintenance
Mobile capable: Yes, with download of Bentley Map Mobile
Summary: OpenCities Map is a combination of CAD and GIS. It excels at intelligent geospatial object creation, spatial analysis, and 3D rendering. It’s also the only option on this list that’s intrinsically 3D. Though it can create, manage, and share 2D information, the built-in 3D functionality is where OpenCities really shines. It also features seamless support for leading spatial databases and includes tools for creating custom GIS applications.
All the platforms below are open-source, meaning that anyone can download them for free. That alone makes them an attractive option for many.
The tradeoff is that functionality is not always comparable to commercial platforms. There’s also little to no training resources or technical support.
Even so, commercial GIS software can be quite expensive, so for individuals and organizations on a budget - open source is often the way to go.
Mobile capable: No
Best for: A free, functionally comparable alternative to ArcGIS
Summary: QGIS is one of the few open-source platforms that’s effectively comparable to ArcGIS. Use it to visualize and analyze geospatial data, as well as to create, edit, and print data-driven maps. Though ArcGIS wins in terms of overall functionality, there are a few ways in which QGIS has ArcGIS beat. QGIS offers unparalleled support for different GIS data types, consuming over 70 different file formats without issue. Moreover, there are no license limits on available tools. Every GIS tool in the QGIS toolbox is available to all users for free.
Mobile capable: Yes, with Android app
Best for: 3D visualization and mobile data collection
Summary: gvSIG was created as an alternative to pricey commercial GIS software. Similar to most platforms on this list, it can accomplish most traditional GIS mapping and data management tasks.

Featuring a native Android app that can be used on Android phones or tablets, gVSIG makes it easy to collect data within the platform. gVSIG also offers a plugin called NavTable, which allows user to navigate visually between GIS data sets. When you select a table in your data set, that same table highlights automatically within the map-based visualization.
Name: SAGA GIS
Mobile capable: No
Best for: High level physical geo-scientific applications, including environmental modeling and terrain analysis
Summary: Originally created as a tool for terrain analysis, SAGA GIS has since grown into a comprehensive GIS system. It excels at environmental modeling, terrain analysis, and other geo-scientific tasks. With lackluster line and point tool sets, it reportedly falls flat in terms of cartographic functionality. However, the raster processing and 3D rendering, both of which are fairly rare in an open-source GIS, are top-notch.
Name: GRASS GIS
Mobile capable: No
Best for: Academic projects, land management, and environmental planning
Summary: GRASS GIS is widely celebrated and used by the academic community. With extensive documentation and an open-source code base, this platform can be tailored to the needs of each specific project. With over 350 different digital tools, GRASS GIS excels at raster and vector manipulation. This toolkit is actually so advanced that other open-source platforms have adopted it into their own codebase.
GRASS GIS does have 3D rendering capabilities, though they are less advanced than other platforms on this list. The primary issues with this platform are the unintuitive user interface and poorly engineered cartography tools. Though it excels at data analysis, it is not recommended for mapping.
Name: Whitebox GAT
Mobile capable: No
Best for: LiDAR conversion and hydrology projects
Summary: Released in 2009, Whitebox GAT is still relatively unknown in the world of GIS. Though it doesn’t have all the same cartography and processing functions as other GIS software applications, it is still fairly advanced. LiDAR conversion, such as LAS to Shapefile, is where the platform really excels. Though ArcGIS does have this functionality, it’s clunky, inconsistent, and difficult to use. With frequent updates, extremely fast processing speeds, and a similar user experience to ArcGIS, Whitebox GAT is considered an up and comer in the world of open-source GIS.
Desktop GIS has been around for decades. As such it a variety of options in terms of functionality and price point.
Though it does have a fairly steep learning curve, for complex data analysis and visualization it really can’t be beat.
In the next section, we’ll explore online GIS.
Online GIS tends to be simpler, easy to use, faster to implement, and significantly less expensive upfront. It also enables field data collection and fast data sharing.
This where software like Unearth's platform, OnePlace, shines.
