Comparing Surfer and QGIS

Comparing Surfer and QGIS

Quite often people will ask, “What are the differences between Surfer and QGIS?” Below is a comparison of the main features and functionality of each program. Surfer, as you may know, provides 2D and 3D contouring complete with surface mapping software. QGIS has an assortment of plugins, and we haven’t been able to review them all. I encourage you review and let me know if there is any missing information. As new information comes in, I’ll be sure to update the matrix below.

Beyond the actual functionality, another difference between Surfer and QGIS is the development models. Surfer is a commercially developed program whereas QGIS is open source and is developed by a community of contributors. While it’s difficult to quantify, I believe it’s worth mentioning the pros and cons, according to me, associated with our commercial software model and QGIS’s open source model.

Updated: Netherlands Company Uses Surfer to Search for Drowning Victim

We recently received an update on the case of the missing diver. The blog has been rewritten to reflect this new information.

November 20, 2011 - Four recreational divers went looking for wreckages at the bottom of De Nieuwe Meer in Amsterdam, Netherlands, an approximately 30 meter deep lake. The group split into two pairs and set out on their adventure. They were well-equipped and all wore full face diving masks.

What Are the Most Popular Commands and Map Types in Surfer?

When you installed Surfer 13, you might have noticed the request to be part of our customer tracking program. What is this? This isn’t where we track your personal data or use any personal information from your computer. What this entails is Golden Software checking to see what commands you use in Surfer. That’s all. We want to see what you click and how many times you click it. 

Why is this important? This tells us which features are used the most, and which features are used the least. The more times a feature is used, the more weight it carries when the time comes for us to discuss which new improvements to include in the next upgrade. For example, if the results show that most people create contour maps and very few people use vector maps, we may favor new features and enhancements for contour maps over vector maps.
