ArcGIS vs. QGIS

I'm very grateful to be able to use it, and I have a master's degree with a focus in Geospatial Analysis. There can be a bit of a learning curve, and I try to build user-friendly ways for volunteers to see & collect data. Meanwhile, if a colleague is less confident with building such a system, it may be more difficult for them to implement.

Well suited:

• To build beautiful and dynamic maps quickly.
• To conduct quantitative and qualitative analyses.
• To work cross-platform, as both the Windows version and the Linux version are identical in appearance and available resources.

Less appropriate:

• To use and import files from proprietary software such as ArcGIS and AutoCAD.

• ArcGIS Online simplifies complicated functions in ArcMap.
• Allows you to layer various data points on top of each other
• Enables for some spreadsheet calculations within the platform (instead of having to do every single step in Excel before bringing it in as a CSV.)

• QGIS is free and very easy to install, and no license is required. Not having to deal with licensing issues has saved me considerable time and frustration.
• The QGIS help community is very active, and it is easy to find answers. Although QGIS does not offer support in the way that ArcMap does, I was always able to google my question and find either a tutorial or website that solved my problem.
• QGIS seems to crash less often than ArcMap. It is super annoying to have a program crash when you are in the middle of a project, but I have not had any issues with QGIS. Also, QGIS is updated frequently.

• There is a steep learning curve for ArcGIS users.
• It takes a lot of computing power for ArcGIS, as it can't be installed on every computer.
• At times, tools can be outdated and there are many similar competitors making more web-based tools that can replace ArcGIS.

• QGIS is hard to use for beginners. A better tutorial and clearer online tutorials could improve this.
• Labeling interface is overly complicated. Allowing users to manually add labels to relevant items could be helpful.
• QGIS should have more "wizards" that can easily import common data points (median income, population density, etc) and cross tabulate that with other categories easily from uploaded data.

Simply because the program deserves it. It seems to me that it is a fundamental tool for the storage, analysis, and interpretation of medium and large-scale phenomena, unmanageable with traditional engineering software. Its versatility in the handling of the different "layers" with which the data is handled and interpolation tools, make this software a powerful ally both for companies and for the educational part of the universities.

Once set up, the tools are extremely easy to use. I had a staff member develop a tool for field data collection, that included an external and internal dashboards to monitor progress in days. The field workers that collected the data, barely knew how to use a computer, and within minutes they could use the application that was configured for them.

I wasn't a GIS user at all when I started using QGIS, nor did I have any background working with data in anything other than Excel, and as a result, I struggled quite a lot in the beginning (it's not quite Google Maps). But having said that, I haven't come across anything that I couldn't do with a little help from the online community. I've done complex spatial analyses on large datasets of metropolitan cities, designed custom multi-page pdf reports that automatically cycle through different areas of an area, etc.

And the GIS staff that I've appointed, after their initial resistance, took to the tool like a fish to water, and I haven't heard them complain after starting to use the tool for a week or two.

But if you're new to GIS, be patient and invest some time to learn how to use the tool. It is absolutely worth it.

ArcGIS' web support is quite good. They also have a broad user base that is active in answering community members' questions. For more sophisticated questions, ArcGIS technical support is good at answering questions, although answers usually are not instantaneously available. I'd also say that ArcGIS is working hard at making its technical support more reachable, at least it appears that way.

Even though there is a no dedicated support team for QGIS (or at least we are not aware of it), there is a huge online community and a large number of forums catering to every question you may have regarding any particular functionality of QGIS. So, you have a lot of help available but you will have to sift through it on the web.

My students love the "drop" feature in Google Maps, but besides that it truly doesn't compare. I love that you can add, delete, or change layers to this map to better understand its larger affect. There are many more ways to manipulate maps on ArcGIS than on Google Maps. I can also add personal details and information if I want to create a specific map, something that I am unable to do with Google

QGIS is open source and freely available for Windows and Mac iOS Geographic Information System Software. QGIS is highly customizable as per project requirements and different application usage. QGIS has ample tools and plugins that are useful for the analysis of raster and vector data. It also supports GRASS, GDAL, and SAGA tools.

• The high availability of training exercises and materials available save valuable faculty time - we don't have to create those materials from scratch.
• The ability to use the software for a wide variety of application spaces gives us maximum flexibility in pursuing extramural funding
• Novel applications developed by our team help facilitate university success

• We can ingest data in any format, and convert it to industry-standard spatial files for hosting on our online GIS platform.
• Many client projects require us to analyze and understand data before we can report on it.
• Because QGIS is free, and the learning curve is negligible for bright GIS technicians, the ROI is practically infinite because the investment is basically zero.
