These alternatives to ArcGIS have one thing in common - they are all generally more user-friendly, and they all lack the capability of ArcGIS. ArcGIS can do most anything geographically-related, while these other products do one or two things very well. For instance, ArcGIS's …
There is a reason why ArcGIS and Esri is still a leader in the spatial data industry. Their tools are irreplaceable, though many other mapping companies are taking the technology further and enabling their maps to be better seen or used on a web-based platform or browser. …
We utilize ArcGIS for each of our units. For example, we just completed our unit on the Middle Ages and are starting our unit on the Renaissance. There is a GeoInquiry that has students manipulate a map to not only see but understand the spread of the plague. They can toggle on and off different layers and icons to see how deadly the plague truly was, and how it led to the rebirth of Europe
CartoDB is great for generating geographic visualizations of data where the geographies are well-defined. It would be great for analysts to develop visualizations of data with spatial elements. That being said, the software is limited if you want to do any real data munging or analysis, as it can be cumbersome to use and there isn't a great interface for actually saving the results of different manipulations (you can save it as a new file, but it's hard to do version control, etc.). I would recommend preparing the data outside of CartoDB and only using the tool for visualization once the data is well prepared.
It is amazing at allowing control of the visualizations. It takes a little bit to get used to but the combination of full SQL queries and CSS-like styling is very powerful.
The services are built on a robust stack of open source software. I was able to build a standalone instance of CartoDB relatively easily (after some research and trial and error).
Server side map rendering is key for handling large data sets. The way the images are returned makes them very easy to catch in an HTTP cache to minimize the hits to the server. The interactivity that CartoDB has built in makes this completely transparent to the end user, they can click on parts of the static images and be presented with popups or change map styles. It's a very clever implementation.
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.
Unlike other platforms (ex: EMSI), there is no "help desk" new users can easily call into for troubleshooting or errors, and so you have to spend LOTS of time trying workarounds. This is also because the help center blog posts are usually pretty confusing, and many times do not include images or videos to help you along. Any such changes would be immensely useful!
ArcGIS and QGIS have a lot of similarities between their products. Where ArcGIS stands out is with their online version of their software. ArcGIS's online solution will pair up with your on-prem solution to offer a fully synchronized system. I wasn't able to duplicate the efforts with QGIS's products and it also requires other 3rd party applications to offer something "somewhat" comparable.
ArcGIS is almost assuredly a positive ROI. The software is nicely packaged with a large user base. If you plan on doing geographic analysis and think there could be a boost to your bottom-line by doing geographic analysis, ArcGIS is the first tool I would turn to.
For some analysts that just want to geocode addresses and plot city, county, or country boundaries, ArcGIS is a negative ROI. There are lots of other tools (free ones) that will accomplish these tasks without investing lots of time and money in ArcGIS. If that's all you're looking for, ArcGIS will turn out to be a negative ROI.
ArcGIS has been a positive ROI for cases involving customer analytics. The software is great for geofencing customers and finding the most optimal targeting of customers.
CartoDB definitely saves a lot of time when creating visualizations. Previously, I would use different software and have to make edits manually (or just create the visualizations manually to start with). I would say that the software definitely cuts the time required to create certain visualizations by a half or two-thirds.
