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.
Suitable for all organisations that are required to collate, store and generate borehole site logs in a timely and orderly fashion. Can also be used for the storage of .ags data if setup correctly. Handles multiple projects well but is not without hiccups when used regularly. I believe it is possible to draw section views however have not done so myself.
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.
I find Holebase much more user-friendly and intuitive although have not used for as long as gINT. It seems to handle the data in a much more reliable way and I've yet to find pesky bugs. Whilst gINT feels like a polished interface to what is in essence a simple database, Holebase feels like a bespoke piece of software.
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.
